AD7622 - 2 MSPS PulSAR ADC

Description

The AD7622 is a 16-bit, 2 MSPS, charge redistribution SAR, fully differential, analog-to-digital converter (ADC) that operates from a single 2.5 V power supply.

Features

  • Throughput 2 MSPS (wideband warp and warp mode) 1.5 MSPS (normal mode) INL: ±0.5 LSB typical, ±1.5 LSB maximum (±23 ppm of FSR) 16-bit resolution with no missing codes Dynamic range: 92.5 dB typical SINAD: 91 dB minimum @ 20 kHz (VREF = 2.5 V) THD:.
  • 115 dB typical @ 20 kHz (VREF = 2.5 V) 2.048 V internal reference: typical drift 8 ppm/°C; TEMP output Differential input range: ±VREF (VREF up to 2.5 V) No pipeline delay (SAR architecture) Parallel (16-, or 8-bit bus) and serial 5 V/3.3 V/2.
