ADS7142IRUGR TI ADC | 10-X2QFN (2x1.5) | 12-bit, 2-Ch, 140 kSPS

Product Overview

The ADS7142IRUGR is a high-performance, 12-bit analog-to-digital converter (ADC) from Texas Instruments, designed for precision data acquisition in space-constrained applications. Housed in a compact 10-pin X2QFN package (2x1.5 mm), this device offers two input channels with a maximum sampling rate of 140 kSPS. It operates from a single 2.35V to 5.5V supply, making it suitable for battery-powered and low-power systems. The ADS7142IRUGR features an I2C-compatible serial interface, internal reference, and programmable gain amplifier (PGA) for flexible signal conditioning.
