Other Parts Discussed in Thread: OPA365

Hi,

I received the question from my customer.

The customer is using OPA365 as an inverting op amp.

Is there a reference circuit diagram for this?

I want to know a recommended feedback resistance value of OPA365 for stable operation.

Best regards,
Seishin

Hi Seishin

Lower feedback resistor values around OPA365 introduce lower noise but will increase power consumption. While higher value of feedback resistors will increase noise keeping power consumption low.

Typically values between 499 Ohm and 2k seems to give best trade off between noise and power consumption.

Thanks & Regards
