General Description
Features
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.
