The ADS1262IPW is a 32-bit high resolution Analog-to-digital Converter (ADC) with programmable gain amplifier (PGA) and voltage reference. The ADS1262 is low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) ADCs with an integrated PGA, reference and internal fault monitors. 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 ADC is 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 130dB rejection of 50 and 60Hz line cycle interference. The ADS1262 is pin and functional compatible.
