ADS1262/63 ADCs

High resolution, low-noise, 32-bit, 38 kSPS ADCs with PGA and internal reference from Texas Instruments

Image of Texas Instruments ADS1262/63 ADCTexas Instruments' ADS1262 and ADS1263 are low-noise, low-drift, 38.4 kSPS, delta-sigma (ΔΣ) ADCs with an integrated PGA, reference, and internal fault monitors. The ADS1263 integrates an auxiliary, 24-bit, ΔΣ ADC intended for background measurements. The sensor-ready ADCs provide complete, high-accuracy, 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 front-end (AFE) incorporates two sensor-excitation current sources suitable for direct RTD measurement. A single-cycle settling digital filter maximizes multiple-input conversion throughput, while providing 130 dB rejection of 50 Hz and 60 Hz line cycle interference.
