AD7694 - 250 kSPS PulSAR ADC

Description

The AD7694 is a 16-bit, charge redistribution, successive approximation, PulSAR™ analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7 V to 5.25 V.

Features

  • 16-bit resolution with no missing codes Throughput: 250 kSPS @ 5 V INL: ±4 LSB max S/(N + D): 92 dB @ 20 kHz THD:.
  • 106 dB @ 20 kHz Pseudo-differential analog input range: 0 V to VREF with VREF up to VDD No pipeline delay Single-supply operation: 2.7 V or 5 V Serial interface SPI®/QSPI™/.
