AD7685 - 250 kSPS PulSAR ADC

Datasheet Summary

Description

The AD76851 is a 16-bit, charge redistribution successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.3 V to 5.5 V.

Features

  • 16-bit resolution with no missing codes Throughput: 250 kSPS INL: ±0.6 LSB typical, ±2 LSB maximum (±0.003% of FSR) SINAD: 93.5 dB at 20 kHz THD:.
  • 110 dB at 20 kHz Pseudo differential analog input range 0 V to VREF with VREF up to VDD No pipeline delay Single-supply operation 2.3 V to 5.5 V with 1.8 V to 5 V logic interface Proprietary serial interface: SPI-/QSPI™-/.
