ADCMP396:  Quad Comparator with Accurate Reference Output

Product Details

Product Status:Recommended for New Designs

The ADCMP396 is a quad, 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 quad ADCMP396 consumes only 41.61 μA of supply current. The low voltage and low current operation of the ADCMP396 makes it ideal for battery-powered systems.

The ADCMP396 features a common-mode input voltage range of 200 mV beyond 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 while the supply voltage is less than the UVLO threshold.

The ADCMP396 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 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.
