AD7381 - 14-Bit SAR ADCs

This page provides the datasheet information for the AD7381, a member of the AD7380 14-Bit SAR ADCs family.

Description

The AD7380/AD7381 are a 16-bit and 14-bit pin-compatible family of dual simultaneous sampling, high speed, low power, successive approximation register (SAR) analog-to-digital converters (ADCs) that operate from a 3.0 V to 3.6 V power supply and feature throughput rates up to 4 MSPS.

Features

  • 16-bit/14-bit ADC family Dual simultaneous sampling Fully differential analog inputs 4 MSPS throughput conversion rate SNR (typical) 92.5 dB, VREF = 3.3 V external at AD7380 (16-bit) 85.4 dB, VREF = 3.3 V external at AD7381 (14-bit) 101 dB with ×16 OSR On-chip oversampling function Resolution boost function INL (maximum) 2.0 LSBs at 16-bit 1.0 LSB at 14-bit 2.5 V internal reference High speed serial interface.
  • 40°C to +125°C operation 16-lead LFCSP, 3 mm × 3 mm Wide common-mode range Ale.
