ADS1262 is a High-res, Low-noise, 32-bit, 38kSPS ADC with PGA and Internal Reference precision

Integrating a low-noise CMOS programmable gain amplifier (PGA), reference, and internal fault monitors, the ADS1262 and ADS1263 are Texas Instruments’ low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) analog-to-digital converters. 

The two 32-bit ΔΣ ADC devices deliver a wide-ranging high-accuracy solution ready to use for the majority of sensor applications such as weight scales, strain-gauge sensors, thermocouples, and resistance temperature devices (RTD). To further drive their application, the devices use a flexible analog front-end (AFE) that features two sensor-excitation current sources suitable for direct measurement. 

Note that the ADS1263 also includes an auxiliary, 24-bit, delta-sigma ADC for background measurements.

In addition, the ADS1262 and ADS1263 include a ΔΣ modulator accompanied by a programmable digital filter, 11 multifunction analog inputs, 8 general-purpose Input/Outputs, dual sensor excitation current sources, and a single-cycle settled digital filter for maximizing multiple-input conversion throughput, while providing 130-dB rejection of 50-Hz and 60-Hz line cycle interference. 

What’s more, both devices are fully specified over the –40°C to +125°C temperature range, pin and functional, and may be procured in a 28-pin TSSOP package.
