OP07C: Replace from OP07C

Part Number: OP07C
Other Parts Discussed in Thread: OPA197, OPA1641

Dear Technical Support Team,

The amplifier circuit by the operational amplifier is used in the AC signal circuit.
However, the linearity and frequency characteristics of the input / output characteristics are not good.

Is there any recommend device for small input signal?

I think low noise amp is better like audio amp.

How about OPA197 and OPA1641?

■my current settings

Input: 10mV AC sine wave

Output: 470mV AC sine wave (about 47 times)

47kΩ(feedback) & 1kΩ for non-inverting amplifier

Input signal frequency: 40Hz〜1kHz

Best Regards,
