Hello Sagar,
Do either the OPA1622 or OPA1641 look appealing for your application? The OPA1622 can operate at a minimum supply of +/-2V. We can put together a simulation if it would help of a pre-amp configuration.
Best Regards,

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…
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…
