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.
