ADS7142-Q1 - Texas Instruments

ADS7142-Q1 Automotive 2-Channel 12-Bit ADC

The ADS7142-Q1 is 12-bit, 140-kSPS successiveapproximation register (SAR) analog-to-digital converter (ADC) that can autonomously monitor signals while maximizing system power, reliability, and performance. The device implements eventtriggered interrupts per channel using a digital window comparator with programmable high and low thresholds, hysteresis, and .
