Hi Jose ,
I am already using OPA1664 as a pre-amplifier and all the four op-amps are used for filtering, and then for the next stage I am using TPA6203A1/ TPA6205A1 for audio amplification, so where in the signal chain volume control should be used…

Howdy,
We've gotten several requests for this, so here it is!
Sorry the scan isn't 100% clear, but the print quality of the book from…

I mean exact bandwidth and slew rate etc…
Thank you
Hi Marc,
Common mode ranges generally refer to the AC characteristics or the signal swing level between the inputs before non-linearity takes into effect due to the signal swings proximity to the supply rails. It does not account for DC offsets between…

Vladimir,
First, there is no such thing as low cost bipolar op amp and no bipolar output can swing within 10mV of either rail since typical VCE saturation voltage is around 300mV at 25 deg C; that is UNLESS you are willing to use a pull-down resistor with…
Robert,
Currently the OPA1662 (dual version of OPA1664 quad) is available. You can order free samples by clicking on link below:

The OPA1664 (quad) will be available later this year.
Hello Eugenio,
The DAC is used as an attenuator in the feedback loop of a mic amp. Basically, the mic amp has a gain equal to the inverse of the
attenuation. Audio Precision frequency response plots show 60 dB of gain at 100 Hz and 1KHz and -6 dB at 20…
