OPA657: Application of the OPA657

Part Number: OPA657
Other Parts Discussed in Thread: TLV3501

Hi team,

My customer use the OPA657 as a comparator. below is the schematic.

So can you help to answer below questions:

1. Please help to review the schematic for the OPA657 used as the comparator.

2. Can the OPA657 be used as the single power supply 5V?  The datasheet indicate the power supply should be more than 8V.

3. With the single power supply +5V, what's the input and output range for the OPA657?

Lacey

Thanks a lot!
