The ADS1274 and ADS1278 are 24-bit, delta-sigma analog-to-digital converters (ADCs) from TI that support simultaneous sampling of four or eight channels and data rates up to 128kSPS.
The ADS1274 (quad) and ADS1278 (octal) are 24-bit, delta-sigma analog-to-digital converters (ADCs) that allow simultaneous sampling of four or eight channels with data rates up to 128k samples per second. These devices combine high-precision industrial measurement capabilities with excellent audio specifications, featuring a high-order, chopper-stabilized modulator for very low drift and an onboard decimation filter to suppress noise.
