The ADS7142-Q1 is a 12-bit, 140-kSPS successive-approximation register (SAR) analog-to-digital converter (ADC) that can autonomously monitor signals while maximizing system power, reliability, and performance. The device implements event-triggered interrupts per channel using a digital window comparator with programmable high and low thresholds, hysteresis, and event counter. The device includes a dual-channel analog multiplexer in front of a SAR ADC followed by an internal data buffer for converting and capturing data from sensors.

The ADS7142-Q1 is available in a 10-pin WSON package and can achieve low power consumption of only 900 nW. The small form-factor and low-power consumption make this device designed for space-constrained applications.
