SINGLE GENERAL PURPOSE
LOW VOLTAGE COMPARATOR
Description
The AZV331 is a low voltage 2.5V to 5.5V, single comparator, which
has a very low supply current of 60µA, making the part an excellent
choice for portable electronic systems. The device is pin-for-pin
compatible replacement of the LMV331.
The AZV331 is built with BiCMOS process with bipolar input and
output stages for improved noise performance. It is a cost-effective
solution for portable consumer products where space, low voltage,
low power and price are the primary specification in circuit design.
The AZV331 is available in space saving SC-70-5 and SOT-23-5
packages, the SC-70-5 is approximately half the size of the SOT-23-
5.
