AD7699 - 500 kSPS PulSAR ADC

Description

The AD7699 is an 8-channel, 16-bit, charge redistribution successive approximation register (SAR) analog-to-digital converter (ADC) that operates from a single power supply, VDD.

Features

  • 16-bit resolution with no missing codes 8-channel multiplexer with choice of inputs Unipolar single-ended Differential (GND sense) Pseudobipolar Throughput: 500 kSPS INL: ±0.5 LSB typical, ±1.5 LSB maximum (±23 ppm or FSR) Dynamic range: 93.3 dB SINAD: 91.5 dB at 20 kHz THD:.
  • 97 dB at 20 kHz Analog input range: 0 V to VREF with VREF up to VDD Multiple reference types Internal 4.096 V External buffered (up to 4.096 V) External (up to VDD) Internal temperature sensor Channel sequencer, sel.
