Texas Instruments ADS1212U-1K is a 22-bit delta-sigma analog-to-digital converter (ADC) featuring a programmable gain amplifier (PGA) and an integrated temperature sensor. This device offers a single differential input channel and a high precision of 22 bits. The ADS1212U-1K utilizes a delta-sigma architecture, providing excellent noise immunity and linearity. Its SPI data interface ensures efficient communication with microcontrollers. Designed for surface-mount applications, it is packaged in an 18-SOIC (0.295", 7.50mm Width) case, supplied on tape and reel. Operating across an industrial temperature range of -40°C to 85°C, this ADC is suitable for applications requiring high-accuracy measurement, including industrial automation, instrumentation, and medical devices. It supports both external and internal voltage references and has a sampling rate of up to 6.25kSPS.
