Data Sheet
General 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 compat i-
ble replacement of the LMV331.
The AZV331 is built with BiCMOS process with bipo-
lar input and output stages for improved noise perfor-
mance. 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.
Features
