Product Details

The ADCMP394 is a single rail-to-rail input low power comparators ideal for use in general-purpose applications. The devices operate from a supply voltage of 2.3V up to 5.5V and draws minimal amount of current. The single ADCMP394 consumes only 36uA of supply current. The low voltage and low current operation of the ADCMP394 makes it ideal for battery-powered systems.

The comparators feature a common-mode input voltage range of 200mV beyond rails, an offset voltage of 1mV typical across the full common-mode range, and an undervoltage lockout (UVLO) monitor. In addition, the design of the comparators allows a defined output state upon power-up. The comparators generate a logic low output while the supply voltage is still below the UVLO threshold.

The comparators incorporate a 1V ±0.8% buffered reference voltage. The reference voltage output can directly connect 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 negative voltage.

The ADCMP394 is available in an 8-pin Narrow Body SOIC package. The ADCMP394 is specified to operate over the extended temperature range of -40°C to +125°C.
