Overview
The AD7980SRMZ-EP is a 16-bit, successive approximation, analog-to-digital converter (ADC) produced by Analog Devices Inc. This device operates from a single power supply and is designed for high-speed and low-power applications. It features a versatile serial interface compatible with SPI, QSPI, MICROWIRE, and DSP, allowing for daisy-chaining of multiple ADCs and an optional busy indicator. The AD7980-EP is particularly suited for defense and aerospace applications due to its enhanced product qualification and controlled manufacturing baseline.
