ADS1262 ADC: Feature, Pinout and Datasheet

Description:

The ADS1262 is low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) ADCs with an integrated PGA, reference, and internal fault monitors. The ADS1262 integrates an auxiliary, 24-bit, ΔΣ ADC intended for background measurements. The sensor-ready ADCs provide complete, highaccuracy, one-chip measurement solutions for the most-demanding sensor applications, including 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 ΔΣ modulator, followed by a programmable digital filter. The flexible analog frontend (AFE) incorporates two sensor-excitation current sources suitable for direct RTD measurement. A single-cycle settling digital filter maximizes multipleinput conversion throughput, while providing 130-dB rejection of 50-Hz and 60-Hz line cycle interference. The ADS1262 is pin and functional compatible. These devices are available in a 28-pin TSSOP package and are fully specified over the –40°C to +125°C temperature range.
