Part Number: OPA1622
Hello All!
I'm experiencing a very odd behavior when trying to use the enable pin feature of the OPA1622 in the clipper circuit below:
As can be seen above, I'm setting the GND pin to -9V in order to reference the enable signal…
Part Number: OPA1622 Hi Team,
My customer uses opa1622 for I / V and differential output stages (driving 32 ohm headphones with 40mW per channel). The power supply voltage of opa1622 is + / - 5V. How much current does this part of the circuit need?
Thanks…

Hello All,
I've received a simple unity gain board that I designed and noticed a very odd behavior: when shorting the OPA1622 enable pin to ground, the output is clipped between -1.4V and +1.6V. It was my understanding that when…

Sorry for bringing up the related thread again, since I missed some points I would like to ask last time.
The question is with regards to the schematic provided in the related…
Jeffrey,
The BUF634 is used for a couple reasons. Basically it is decoupling the precision amplifier (OPA1622) from the load (headphones). With its large slew rate the BUF634 is able to reproduce the signal seen at it's input coming from the precision…

Part Number: OPA1622 Hello, the enable function does'nt work on 8 x OPA1622 after power supply sequencing. It is possible to turn the op amps correctly on if enable is high. If low, the OPA1622 pulls out a strong distorted 2Vrms signal. This happens if…
