HMCAD1520 Overview

The HMCAD1520 is a versatile high performance low power analog-to-digital converter (ADC), with interleaving High Speed Modes to increase sampling rate. Integrated Cross Point Switches activate the input selected by the user. In Single Channel Mode, one of the four inputs can be selected as valid input to the single ADC channel. In Dual Channel Mode, any two of the four inputs can be selected to each ADC channel. In Quad Channel Mode and Precision Mode, any input can be assigned to any ADC channel. An internal, low jitter and programmable clock divider makes it possible to use a single clock source for all operational modes.

The HMCAD1520 is based on a proprietary structure, and employs internal reference circuitry, a serial control interface and a serial LVDS output data. Data and frame synchronization clocks are supplied for data capture at the receiver. Internal digital fine gain can be set separately for each ADC to calibrate for gain errors. Various modes and configuration settings can be applied to the ADC through the serial control interface (SPI). each channel can be powered down independently and output data format can be selected through this interface. A full chip idle mode can be set by a single external pin. Register settings determine the exact function of this pin. HMCAD1520 is designed to interface easily with Field Programmable Gate Arrays (FPGAs) from several vendors. This blog will introduce HMCAD1520 systematically from its features, pinout to its specifications, applications, also including HMCAD1520 datasheet and so much more.

Using Warnings

Note: Please check their parameters and pin configuration before replacing them in your circuit.


1. How does an AD converter work?

When converting analog signals to digital, ADCs follow a set of steps. They sample the signal first, then quantify it to determine the signal's resolution, and finally set binary values and send it to the system to read the digital signal. The sampling rate and resolution of the ADC are two critical parameters.

2. What is AD to DA converter?

An analog-to-digital converter (ADC, A/D, or A-to-D) is a system in electronics that converts an analog signal into a digital signal, such as a sound picked up by a microphone or light entering a digital camera.

3. Why do we need ADC and DAC?

Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) are critical components in electronic devices. Because most signals in the real world are analog, these two converting interfaces are required to allow digital electronic equipment to process analog signals.
