Part Number: INA1620EVM Tool/software: Hi!:
As the title says, are there any gerbers or CAD files that TI would not mind sharing for this EVM?

Part Number: INA1620EVM Other Parts Discussed in Thread: TPA3126D2EVM , PCM2903EVM-U , , INA1620 Hi!
I am looking for a stereo pre amp EVM that can take analog audio input from the PCM2903EVM-U DAC, and function as a volume regulator, and send the signal…
Part Number: INA1620EVM Hi!
I have bought the INA1620EVM. The documentation can be found here: https://www.ti.com/lit/ug/sbou205/sbou205.pdf
But there is an error - a contradiction - on page 5 - Section 3.2 - Cutoff Frequency:
When you look at the…
Hi Jason,
There are two typos in the clip shown above. First, "R5" should read "R15".
Next, in equation 4, the first reference of R7 should be R6, so, Vrightchanneloutput = (R 6 /R6+R7)... Now, when using R1=R7=1k, and R2=R6=2k, both equations will…
Part Number: INA1620EVM Hello,
I'm a bit confused. I replaced R1 & R7 with 1kohm resistors, and R2 & R6 with 10kohm resistors. I'm feeding the right channel audio input 1v. However I'm only getting 1.75v on the output, or 4.86db of gain. I thought…
Part Number: INA1620EVM Hello,
I’m just wondering what mods need done to the INA1620EVM board in order to achieve 18dB gain, without any filtering? If possible I’d like to only utilize the internal chip resistors.
Thanks,
Mike
Hey Benjamin,
To add on to Raymond's comments I have tested the INA1620 EVM in the past to drive headphones into 3 ohms (very heavy load) and it worked very well. I tested with +/-4.75V though. With 32 ohms you will be a magnitude of 10 times lighter…
OK. Thank you. I will have to adjust the volume before the TPA3126D2EVM power stage.
Considering that the signal comes from the PCM2903EVM-U DAC:
Do you have any recommendations for an amp stage before the TPA3126D2EVM to make the volume fully adjustable…
