Analog Devices Inc. AD7770ACPZ-RL

Description
The AD7770 is an 8-channel, simultaneous sampling analog-to-digital converter (ADC) with a programmable gain amplifier (PGA) per channel. It offers low dc input current, high output data rates, and a sample rate converter (SRC) for coherent sampling. The AD7770 has two power modes: high resolution mode and low power mode, optimizing power dissipation and performance. It also includes a 12-bit SAR ADC for system and chip diagnostics.
