Overview
The AD7980BCPZ-R2 is a high-performance, 16-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This ADC operates from a single power supply and features a low power, high speed design. It includes a versatile serial interface port compatible with SPI, allowing for daisy-chaining of multiple ADCs on a single 3-wire bus. The device is housed in a 10-lead LFCSP package and is specified to operate over a temperature range of −40°C to +125°C.
