    VFC320BP Product overview

    The VFC320BP is a monolithic Voltage-to-Frequency and Frequency-to-Voltage Converter provides a simple low cost method of converting analog signals into digital pulses. The digital output is an open collector and the digital pulse train repetition rate is proportional to the amplitude of the analog input voltage. Output pulses are compatible with TTL and CMOS logic families. High linearity (0.005%, maximum at 10kHz FS) is achieved with relatively few external components. Two external resistors and two external capacitors are required to operate. Full scale frequency and input voltage are determined by a resistor in series with-In and two capacitors (one-shot timing and input amplifier integration). The other resistor is a non-critical open collector pull-up (fOUT to +VCC). The VFC320 is available in two performance grades. The VFC320 is specified for the -25 to +85°C range.

    AD637JQ Product overview

    The AD637JQ is a complete, high accuracy, RMS-to-DC Converter that computes the true rms value of any complex waveform. It offers performance that is unprecedented in integrated circuit RMS-to-DC converter and comparable to discrete and modular techniques in accuracy, bandwidth and dynamic range. This computes the true root mean square, mean square or absolute value of any complex AC (or AC plus DC) input waveform and gives an equivalent dc output voltage. The true rms value of a waveform is more useful than an average rectified signal because it relates directly to the power of the signal. The rms value of a statistical signal relates to the standard deviation of the signal. Superior crest factor compensation permits measurements of signals with crest factors of up to 10 with less than 1% additional error.
