Analog Devices Inc. ADCMP396 Quad Comparator

Analog Devices Inc. ADCMP396 Quad Comparator with Accurate Reference Output is offered as a quad, rail-to-rail input, low power comparator ideal for use in general-purpose applications. ADCMP396 operates from a supply voltage of 2.3V to 5.5V, draws a minimal amount of current, and consumes only 41.61μA of supply current. With its low voltage and low current operation, the ADCMP396 is ideal for battery-powered systems. The ADCMP396 incorporates a 1V ± 0.9% buffered reference voltage. Designers can directly connect the reference the voltage output to the comparator input to serve as the trip value for precise monitoring and detection of positive voltage. It can also act as an offset when monitoring the negative voltage. 

The ADCMP396 features a common-mode input voltage range of 200mV beyond rails, an offset voltage of 1mV typical across the full common-mode range, and a UVLO monitor. In addition, the design of the comparator allows a defined output state upon power-up. The comparator generates a logic low output while the supply voltage is less than the UVLO threshold. The ADCMP396 is available in a 16-lead narrow-body SOIC package, and it is specified to operate over the −40°C to +125°C extended temperature range.
