The ADS1261BIRHBR is a precision, 24-bit, delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It offers a maximum sampling rate of 40 kSPS and supports up to 10 input channels via a multiplexed configuration. The device accepts both differential and single-ended input signals.
The ADC integrates a low-noise programmable gain amplifier (PGA) with gains from 1 to 128, an internal 2.5-V voltage reference, and two programmable excitation current sources (iDACs). Key performance specifications include a typical offset drift of 1 nV/°C, gain drift of 0.5 ppm/°C, and noise of 30 nV RMS at 20 SPS with a gain of 128. It also features 50/60 Hz rejection, a temperature sensor, and CRC data integrity checking.
The ADS1261BIRHBR operates from either a unipolar 4.75-V to 5.25-V supply or a bipolar ±2.5-V supply. The digital interface is SPI. It is housed in a 32-pin VQFN package with an exposed pad (5 mm × 5 mm) and is rated for surface mount assembly over a -40°C to +125°C temperature range.
