Part Number: OPA1622 Other Parts Discussed in Thread: BUF634 , Hi TI staff,
I would like to ask related question based on a thread " PCM512 + OPA1622 + BUF634" started by user..
My question refers to a schematic provided by TI staff member during…
Part Number: OPA1622 Other Parts Discussed in Thread: BUF634 , PCM5102 Hi there !
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…
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…

Hi team,
Could you please suggest BA3308F TI cross?
My customer is looking for EOL replacement device.
ALC is not needed, please just recommend hero dual audio amps.

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 Other Parts Discussed in Thread: OPA1611 , OPA2192
Hi, I am currently working on a headphone amplifier. The goal of the headphone amplifier is to have unmeasurably low distortion levels. For this reason a cascaded outputstage with…
Part Number: OPA1622 Other Parts Discussed in Thread: INA1620 , , BUF634A , OPA210 , BUF634 , NE5534 I'm thinking of using the OPA1622 as a parallel buffer to drive a line output transformer with a 33Ω-100Ω primary impedance and a 10dBu step up. Power is 24V…
Part Number: INA1620 Other Parts Discussed in Thread: OPA1622 , LM4562 , TINA-TI , OPA827 , OPA828 I am a little mystified as to how the high bias current of these devices interacts with resistances in the bias position and on the inverting input. Part of…
Part Number: OPA1622 Looking for info, appnotes, etc. on output characteristics during shutdown . With head phone like loads (using the eval board) the output seems controlled and quiet. With higher load impedances (100k) the output during shutdown is…
Part Number: OPA1622 Other Parts Discussed in Thread: , OPA1688 Could the OPA1622 be used with a single supply? I tried connecting +5V to the VCC of the OPA1622EVM and connected the VEE pin to the GND pin (and to the return of the power supply). The audio…
