AD7367BRUZ FAQ

 

AD7367BRUZ Product Overview

The AD7367BRUZ is a pair of sequential approximation, 12-bit/14-bit, high speed, low power analog-to-digital converters (ADCs) with throughput rates up to 1 MSPS. The device has a low noise, wide bandwidth track-and-hold amplifier as well as two ADCs, each preceded by a 2-channel multiplexer.

 

The Analog Devices, Inc., industrial CMOS process (iCMOS2), a technology platform fusing the benefits of low and high voltage CMOS, is used to create the AD7367BRUZ. The AD7367BRUZ can receive high voltage bipolar signals thanks to the iCMOS technology, which also lowers power consumption and package size. The 0 V to 10 V range, the ±10 V range, and the ±5 V range are all valid input ranges for the AD7367BRUZ.

 

The on-chip 2.5 V reference of the AD7367BRUZ can be turned off to enable the use of an external reference. The AD7367BRUZ is capable of accepting a full bipolar ±12 V analog input if a 3 V reference is given to the DCAPA and DCAPB pins. The ±12 V input range requires at least ±12 V VDD and VSS supply.

 

Product Highlights

  1. The AD7366/AD7367 can accept true bipolar analog input signals, as well as ±10 V, ±5 V, ±12 V (with external reference), and 0 V to 10 V unipolar signals.
  1. Two complete ADC functions allow simultaneous sampling and conversion of two channels.
  1. 1 MSPS serial interface: SPI-/QSPI-/DSP-/MICROWIRE-compatible interface.

AD7367BRUZ Pin Configuration

The following figure is the AD7367BRUZ Pin Configuration.

Figure: Pin Configuration

Pin Number Pin Name Desription
1, 23 DOUTA, DOUTB Serial Data Outputs. The data output is supplied to each pin as a serial data stream. The bits are clocked out on the falling edge of the SCLK input; 12 SCLK cycles are required to access a result from the AD7366, and 14 SCLK cycles are required for the AD7367. The data simultaneously appears on both pins from the simultaneous con versions of both ADCs. The data stream consists of the 12 bits of conversion data for the AD7366 and 14 bits for the AD7367 and is provided MSB first. If CS is held low for a further 14 SCLK cycles, on either DOUTA or DOUTB, the data from the other ADC follows on that DOUT pin. Note, the second serial result from the AD7366 is preceeded
by two zeros. Therfore data from a simultaneous conversion on both ADCs can be gathered in serial format on either DOUTA or DOUTB using only one serial port.
2 VDRIVE Logic Power Supply Input. The voltage supplied at this pin determines at what voltage the interface operates. This pin should be decoupled to DGND. The voltage range on this pin is 2.7 V to 5.25 V and may be different from the voltage at AVCC and DVCC, but should never exceed either by more than 0.3 V. To achieve a throughput
rate of 1.12 MSPS for the AD7366 or 1 MSPS for the AD7367, VDRIVE must be ≥ 4.75 V.
3 DVCC Digital Supply Voltage, 4.75 V to 5.25 V. The DVCC and AVCC voltages should ideally be at the same potential. For best performance, it is recommended that the DVCC and AVCC pins be shorted together, to ensure that the voltage difference between them never exceeds 0.3 V even on a transient basis. This supply should be decoupled to DGND. Place 10 µF and 100 nF decoupling capacitors on the DVCC pin.
4, 5 RANGE1, RANGE0 Analog Input Range Selection, Logic Inputs. The polarity on these pins determines the input range of the analog
input channels.
6 ADDR Multiplexer Select, Logic Input. This input is used to select the pair of channels to be simultaneously converted, either Channel 1 of both ADC A and ADC B, or Channel 2 of both ADC A and ADC B. The logic state on this pin is latched on the rising edge of BUSY to set up the multiplexer for the next conversion.
7, 17 AGND Analog Ground. Ground reference point for all analog circuitry on the AD7366/AD7367. All analog input signals and any external reference signal should be referred to this AGND voltage. Both AGND pins should connect to the AGND plane of a system. The AGND and DGND voltages should ideally be at the same potential and must not be more than 0.3 V apart, even on a transient basis.
8 AVCC Analog Supply Voltage, 4.75 V to 5.25 V. This is the supply voltage for the ADC cores. The AVCC and DVCC voltages should ideally be at the same potential. For best performance, it is recommended that the DVCC and AVCC pins be shorted together, to ensure that the voltage difference between them never exceeds 0.3 V even on a transient
basis. This supply should be decoupled to AGND. Place 10 µF and 100 nF decoupling capacitors on the AVCC pin.
9, 16 DCAPA, DCAPB Decoupling Capacitor Pins. Decoupling capacitors are connected to these pins to decouple the reference buffer for each respective ADC. For best performance, it is recommended that a 680 nF decoupling capacitor be used on these pins. Provided the output is buffered, the on-chip reference can be taken from these pins and applied externally to the rest of a system.
10 VSS Negative Power Supply Voltage. This is the negative supply voltage for the high voltage analog input structure of the AD7366/AD7367. The supply must be less than a maximum voltage of −11.5 V for all analog input ranges. Place 10 µF and 100 nF decoupling capacitors on the VSS pin.
11, 12 VA1, VA2 Analog Inputs of ADC A. Both analog inputs are single-ended. The analog input range on these channels is determined by the RANGE0 and RANGE1 pins.
13, 14 VB2, VB1 Analog Inputs of ADC B. Both analog inputs are single-ended. The analog input range on these channels is determined by the RANGE0 and RANGE1 pins.
15 VDD Positive Power Supply Voltage. This is the positive supply voltage for the high voltage analog input structure of the AD7366/AD7367. The supply must be greater than a minimum voltage of 11.5 V for all analog input ranges. Place 10 µF and 100 nF decoupling capacitors on the VDD pin.
18 REFSEL Internal/External Reference Selection, Logic Input. If this pin is tied to logic high, the on-chip 2.5 V reference is used as the reference source for both ADC A and ADC B. In addition, Pin DCAPA and Pin DCAPB must be tied to decoupling capacitors. If the REFSEL pin is tied to GND, an external reference can be supplied to the AD7366/
AD7367 through the DCAPA pin, the DCAPB pin, or both pins.
19 CS Chip Select, Active Low Logic Input. This input frames the serial data transfer. When CS is logic low, the output bus is enabled and the conversion result is output on DOUTA and DOUTB.
20 SCLK Serial Clock, Logic Input. A serial clock input provides the SCLK for accessing the data from the AD7366/AD7367.
21 CNVST Conversion Start, Logic Input. This pin is edge triggered. On the falling edge of this input, the track/hold goes into hold mode and the conversion is initiated. If CNVST is low at the end of a conversion, the part goes into power-down mode. In this case, the rising edge of CNVST instructs the part to power up again.
22 BUSY Busy Output. BUSY transitions high when a conversion is started and remains high until the conversion is complete.
24 DGND Digital Ground. Ground reference point for all digital circuitry on the AD7366/AD7367. The DGND pin should connect to the DGND plane of a system. The DGND and AGND voltages should ideally be at the same potential and must not be more than 0.3 V apart, even on a transient basis.

AD7367BRUZ FAQ

What is an Analog-to-Digital converters?

Analog-to-Digital converters (ADC) translate analog signals, real world signals like temperature, pressure, voltage, current, distance, or light intensity, into a digital representation of that signal. This digital representation can then be processed, manipulated, computed, transmitted or stored.

 

Which is an example of analog-to-digital converter?

Examples of analogue signals include temperature, pressure, liquid levels and light intensity. For a digital circuit the potentiometer wiper has been replaced by a single rotary switch which is connected in turn to each junction of the series resistor chain, forming a basic potential divider network.

 

What is the function of ADC?

An ADC is used to convert an analogue signal such as voltage to a digital form so that it can be read and processed by a microcontroller. Some microcontrollers have built-in ADC converters. It is also possible to connect an external ADC converter to any type of microcontroller.
