AD7262 - Simultaneous Sampling SAR ADC

Description

The AD7262/AD7262-5 are dual, 12-bit, high speed, low power, successive approximation ADCs that operate from a single 5 V power supply.

Features

  • Dual simultaneous sampling 12-bit, 2-channel analog-todigital converter (ADC) True differential analog inputs Programmable gain stage: ×1, ×2, ×3, ×4, ×6, ×8, ×12, ×16, ×24, ×32, ×48, ×64, ×96, ×128 Throughput rate per ADC 1 MSPS for AD7262 500 kSPS for AD7262-5 Analog input impedance: >1 GΩ Wide input bandwidth.
  • 3 dB bandwidth: 1.7 MHz at gain = 2 4 on-chip comparators SNR: 73 dB typical at gain = 2, 66 dB typical at gain = 32 Device offset calibration, system gain calibration On-chip r.
