Product Details
●The ADCMP394/ADCMP395/ADCMP396 are single/dual/quad rail-to-rail input, low power comparator ideal for use in general-purpose applications. These comparators operate from a supply voltage of 2.3 V to 5.5 V and draw a minimal amount of current. The single ADCMP394 consumes only 33.9 µA of supply current. The dual ADCMP395 and quad ADCMP396 consumes 37.2 µA and 41.6 µA of supply current respectively. The low voltage and low current operation of these devices makes it ideal for battery-powered systems.
●The comparators 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 if the supply voltage is less than the UVLO threshold.
●The ADCMP394/ADCMP395/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 ADCMP394 and ADCMP396 are available in 8-pin and 16-lead, narrow body SOIC package, respectively. The ADCMP395 is available in a 10-lead MSOP package. The comparators are specified to operate over the −40°C to +125°C extended temperature range.
