Part Number: OPA1622 Hello,
the typical EN pin input current for +25°C is given in the datasheet with 1.5 uA. Please specify the maximum input current considering the temperature range -40..125 °C.
Is the input current caused by a pull-up or a…

Hi team,
I downloaded the OPA1622 model on TI's website and used TINA TI to simulate the phase margin at different capacitive loads and found the simulation results to be inconsistent with the datasheet curve.
According to the…

Hello,
I would like to use OPA1622 directly on output of high-end DAC using the following DAC-vendor-recommended circuit:
Are there any concerns with the component values in this…
Chris, Zach -
I'm back from looking at high speed amps, less than enthused at cost / Iq / Vos. Which is OK, because I figured out a way to do it with an OPA1602. There is no peaking and phase is aligned out to 800kHz. Huzzah.
You'll see why the Rf…
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,

I connected pin 8 (EN) of OPA1622 to V+ (+12V), pin 3 (GND) to V- (-12V) instead of GND, and connected the other pins as specified and continued to use them.
If so, what are the possible inconveniences?
Part Number: OPA1622 I connected the 8th pin (EN) of the OPA1622 to V+ (+12V), the 3rd pin (GND) to V- (-12V) instead of GND, and connected the other pins as specified and continued to use them.
If so, what kind of failures and effects are possible? …
Part Number: OPA1622 Other Parts Discussed in Thread: INA1620 , TINA-TI Has anyone ever tried the OPA1622 in parallel operation (to increase output current)? Is there by chance an app note for this configuration?
Would you say the 1622 is better suited…
Part Number: OPA1622 Other Parts Discussed in Thread: INA1620 Hello,
I have to design an audio driver to drive a handset or headset:
Handset - 20 ohms and sensitivity 107 dB@1 mW
Headset - 625 ohms and sensitivity 112 dB@ 1mW
What op amp do you recommend…
Part Number: OPA1622
I am trying to add the OPA1622 op amp to an LTSpice schematic. I downloaded the OPA1622 PSpice model shown above. However, I cannot tell which file in the download is the file to use for the LTSpice model.
Can you please tell me…
