ADCMP395:  Dual Comparator with Accurate Reference Output

Product Details


The ADCMP395 is a dual, rail-to-rail input, low power comparator ideal for use in general-purpose applications. The device operates from a supply voltage of 2.3 V to 5.5 V and draws a minimal amount of current. The dual ADCMP395 consumes only 37.2 μA of supply current. The low voltage and low current operation of the ADCMP395 make it ideal for battery-powered systems.

The ADCMP395 features a common-mode input voltage range of 200 mV beyond the rails, an offset voltage of 1 mV 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 when the supply voltage is less than the UVLO threshold.

The ADCMP395 incorporates a 1 V ± 0.9% 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 the negative voltage.

The ADCMP395 is available in a 10-lead MSOP package, and is specified to operate over the −40°C to +125°C extended temperature range.
