Description

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

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