Part Number: LMV321
Other Parts Discussed in Thread: LM321LV, TLV6002, TLV9151, TLV9001

Hi,

Customer looks for replacement for ST LMV321. His concercern is p2p(SOT23-5) and offset.

The offset of ST/LMV321 is 0.1mV(TYP). TI LM321LV is 1mV, and TLV6002 is 0.75mV. TLV9151 is 0.125mV, but it is not p2p.

Is there any better suggestion to replace ST LMV321?

Thanks and regards,

Hey David,

TLV9001 has a lower max offset and is offered in a pin to pin package. The typical offset is 0.4mV, but the max offset is better (1.6mV vs 3mV). The TLV9001UIDBVR has the matching pinout.

Best,
Jerry

Hi Jerry,

RD's concern is typical offset. Is there any better suggestion except TLV9001UIDBVR?

Thnaks and best regards,

Hey David,

Our parametric tables filter by maximum offset, not typical. Is there a specific reason the customer is looking at typical offset? This is a tested limit and having a lower max will mean you will not see as high of a value in your application.

Best,
Jerry
