AD4000 - SAR ADC

Description

The AD4000/AD4004/AD4008 are high accuracy, high speed, low power, 16-bit, precision successive approximation register (SAR) analog-to-digital converters (ADCs).

Features

  • Easy Drive expands signal chain flexibility.
  • High-Z mode significantly reduces signal chain settling requirements.
  • Fast conversion phase extends the ADC acquisition time.
  • Input overvoltage protection clamp sinks up to 50 mA.
  • High performance.
  • First conversion accurate, no latency or pipeline delay.
  • Guaranteed 16-bit, no missing codes.
  • Throughput: 2 MSPS/1 MSPS/500 kSPS options.
  • INL: ±1.0 LSB maximum.
  • SNR: 93 dB at fIN = 1 kHz, VREF = 5 V.
  • T.
