OP07C: psrr

Dear expert,

My customer is wondering what the PSRR of OP07C is at 200kHz. Where to find in the datasheet? Thanks.

Well the OP07c is made by several folks - likely the same circuit,

If I look at the ADI version is shows this - projecting from a 50dB at 2kHz down 40dB from there at 200kHz, suggests a dismal 10dB PSRR.

Michael's 10dB PSRR figure is likely very closed to OP07C's performance, since OP07E (analog) and OP07x's specification look very similar.

Please let us know if you have additional questions.

Best,

Raymond

Hi Minqi,

why is the customer asking? Is he planning to supply the OP07 with a DC/DC-converter?
