AD7921 - 10-/12-Bit ADCs

Download the AD7921 datasheet PDF. This datasheet also covers the AD7911 variant, as both devices belong to the same 10-/12-bit adcs family and are provided as variant models within a single manufacturer datasheet.

General Description

The AD7911/AD79211 are 10-bit and 12-bit, high speed, low power, 2-channel successive approximation ADCs, respectively.

The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates of up to 250 kSPS.

Key Features

  • Fast throughput rate: 250 kSPS Specified for VDD of 2.35 V to 5.25 V Low power: 4 mW typ at 250 kSPS with 3 V supplies 13.5 mW typ at 250 kSPS with 5 V supplies Wide input bandwidth: 71 dB minimum SNR at 100 kHz input frequency Flexible power/serial clock speed management No pipeline delays High speed serial interface: SPI®/QSPI™/.
