ADS1274 - (ADS1274 / ADS1278) 24-Bit Analog-to-Digital Converters

This page provides the datasheet information for the ADS1274, a member of the ADS1274_Burr (ADS1274 / ADS1278) 24-Bit Analog-to-Digital Converters family.

Datasheet Summary

Description

Based on the single-channel ADS1271, the ADS1274 (quad) and ADS1278 (octal) are 24-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with data rates up to 128k samples per second (SPS), allowing simultaneous sampling of four or eight channels.

Features

  • Simultaneously Measure Four/Eight Channels Up to 128kSPS Data Rate AC Performance: 62kHz Bandwidth 111dB SNR (High-Resolution Mode).
  • 108dB THD DC Accuracy: 0.8μV/°C Offset Drift 1.3ppm/°C Gain Drift Selectable Operating Modes: High-Speed: 128kSPS, 106dB SNR High-Resolution: 52kSPS, 111dB SNR Low-Power: 52kSPS, 31mW/ch Low-Speed: 10kSPS, 7mW/ch Linear Phase Digital Filter SPI™ or Frame-Sync Serial Interface Low Sampling Aperture Error Modulator Output Option (digital filter bypass) Analog.
