Part Number: OPA1662 Other Parts Discussed in Thread: OPA134 , OPA1642 Are there any special precautions that have to be considered while dealing with OPA1662s? I am an electrical engineer designing hi-end audio preamplifiers for the past 20 years. Recently…
Hello Stefano,
Looks like the OPA1662 you were originally using was damaged. With a good OPA1662, the circuit behaves as expected. I will close this thread now.

Hi User,
The reason why you are seeing a signal even when there is no mic input is because pin 3 of the OPA1662 does not have a bias current return path to ground. This is one of the most common problems when there is no dc return path for bias current…
Part Number: PCM1690 Other Parts Discussed in Thread: OPA1662 , TPA3251 , PCM4104 Hello all,
i'd need a little reassurance if what i'm trying to design will actually work:
A PCM1690 differential DAC is used for conversion from a DSP. Using an OPA1662…
Part Number: OPA1662 hi,
I just need a confirmation that opa1662 doesn't feature any protection on the output in case a low impedance is connected from OUT to GND.
What happens if the output current is >>10mA (abs.max)?
thanks a lot in adva…
Part Number: PGA970EVM Other Parts Discussed in Thread: OPA1662 , PGA970 , OPA350 Good afternoon everyone,
I got a PGA970EVM a few days ago and I found a strange behavior with the OPA1662 output driver. Although it shows a sine signal output when without…
