GENERAL DESCRIPTION VCC
The ADCMP394/ADCMP395/ADCMP396 are single/dual/quad
ADCMP396
rail-to-rail input, low power comparator ideal for use in general-
REF REF
purpose applications. These comparators operate from a supply
INA+ OUTA
voltage of 2.3 V to 5.5 V and draw a minimal amount of
INA–
current. The single ADCMP394 consumes only 33.9 μA of
INB+ OUTB INB–
supply current. The dual ADCMP395 and quad ADCMP396
INC+
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.

GND
122 of 200 mV beyond rails, an offset voltage of 1 mV typical across Figure 3. 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.
