AD7641 - 18-Bit 2-MSPS SAR ADC

Description

The AD7641 is an 18-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: ±2 LSB typical, ±3 LSB max; ±8 ppm of full scale 18-bit resolution with no missing codes Dynamic range: 95.5 dB SNR: 93.5 dB typical @ 20 kHz (VREF = 2.5 V) THD:.
  • 112 dB typical @ 20 kHz (VREF = 2.5 V) 2.048 V internal reference: typ drift 10 ppm/°C; TEMP output Differential input range: ±VREF (VREF up to 2.5 V) No pipeline delay (SAR architecture) Parallel (18-, 16-, or 8-bit bus) and serial 5 V/3.3 V/2.5 V inte.
