Texas Instruments  ADS7142IRUGR

The ADS7142 autonomously monitors signals while optimizing system power, reliability, andperformance. It implements event-triggered interrupts per channel using a digital windowedcomparator with programmable high and low thresholds, hysteresis, and event counter. The deviceincludes a dual-channel analog multiplexer in front of a successive approximation registeranalog-to-digital converter (SAR ADC) followed by an internal data buffer for converting andcapturing data from sensors.

The ADS7142 is available in 10-pin QFN package and consumes only 900 nW of power. Thesmall form-factor and low power consumption make this device suitable for space-constrained and/orbattery-powered applications.
