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…
Part Number: OPA1622
Hello,
We are using the OPA1622 for an amplifier application. When we use 2.2k input resistors, and 10k feedback resistors for a gain of 4.54x, the circuit performs flawlessly. However when we swap the resistors to 33k for the input…
Part Number: OPA1622 I have built a high-performance audio DAC using the OPA1622. I used +/-15 volts to power the op-amps. I can't seem to find any data in the OPA1622 datasheet that discusses the performance of these op-amps with different supply voltages…
Part Number: OPA1622 Hello dear TI community. I've got rahter simple question about enable pin of OPA1622 amplifier. I'll use demux 2:1 IC to switch enable signal between pairs of OPA1622 in my design. I picked SN74LVC1G18 for this job - input of this…
Part Number: OPA1622 Hi Experts
My customer needs to operate the device in some cases below -40C. They would like to know the following:
Are the dotted lines untested extrapolations?
What is their source and can they be designed to?
Do the dotted lines…
