Overview
The AD7980ACPZ-RL is a 16-bit, successive approximation, analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This component is part of the PulSAR series and is designed for high-performance data acquisition applications. It operates from a single power supply and features a low power, high speed sampling ADC along with a versatile serial interface port. The AD7980 is housed in a 10-lead LFCSP (Lead Frame Chip Scale Package) and is specified to operate over a temperature range of −40°C to +125°C.
