It communicates over an I²C interface and accepts both differential and single-ended inputs, making it a compact front-end for precision sensor acquisition. ## 1 kSPS sampling with industrial temperature range The 1 kSPS sampling rate suits low-bandwidth measurement channels such as thermocouples, strain gauges, or pressure transducers. Supply voltage for both analog and digital rails spans 2.3 V to 5.5 V, allowing single-supply operation from a 3.3 V or 5 V rail without a separate regulator for the digital core. ## Active production – sourcing and package options It is offered in Tape & Reel (TR) and Cut Tape (CT) packaging, which covers both volume reel and prototype quantities. ## 16-WQFN footprint and thermal pad The 16-WQFN (3x3 mm) package has an exposed thermal pad that must be soldered to a PCB copper plane for rated thermal performance. The 0.50 mm pitch demands careful fan-out on a 2-layer board; a 4-layer stack-up with a solid ground plane under the pad is recommended for lowest noise.","metaTitle":"ADS1219IRTET 24-Bit Sigma-Delta ADC – Texas Instruments","metaDescription":"ADS1219IRTET 24-bit sigma-delta ADC, 1 kSPS, I²C, PGA, 4-channel MUX, -40°C to 125°C, 16-WQFN.
