Low-noise low-drift 38.4kSPS delta-sigma analog-to-digital converters

Texas Instruments' ADS126x low-noise low-drift, 38.4kSPS analog-to-digital delta-sigma (?S) converters are now stocked by Mouser. They come with an integrated PGA, reference, and internal fault monitors. The ADS1263 integrates an auxiliary, 24-bit, ?S ADC intended for background measurements. These sensor-ready ADCs provide complete, high-accuracy, one-chip measurement solutions for the most-demanding sensor applications. This includes weigh scales, strain-gauge sensors, thermocouples, and resistance temperature devices (RTD). The ADCs are comprised of a low-noise, CMOS PGA (gains 1 to 32), a ?S modulator, followed by a programmable digital filter. The flexible analog front-end (AFE) incorporates two sensor-excitation current sources suitable for direct RTD measurement.
