Hello Lance,
We do offer the DEM-OPA-RGV-EVM , which is an generic EVM board designed for VQFN (RGV) package PLC and DSL line drivers. The associated user's guide showcases the EVM functionality, which can do either two amplifier channels or a single differential…
Joaquin,
There is an EVM available which you can get from TI.com to test yor circuit (link below)
https://www.ti.com/tool/DEM-OPA-RGV-EVM
In your schematic (snippet below) the input swings from 0V to 3.3V, so for the time period in which it is 0V, it…
Hi Arvind,
Unfortunately the DEM-DAI3168A EVM is discontinued. We know there's demand for this EVM and are hoping to have a new EVM released in either 2Q or 3Q this year.
Best regards, Jeff McPherson
Hello D,
1) I found in DS of OPA360 page6 ( Enable/Shutdown) section
"If the Enable pin is not connected, internal pull-up circuitry will enable the amplifier."
But it is probably better to tie it to 3.3V
- I agree, you may float it but I recommend…
Hi,
Can you check why the clocks are with 0 offset, going negative?
See page 19 onwards of the datasheet for timing diagram.
24-Bit, 96/192 kHz Asynchronous Stereo Audio Codec datasheet (Rev. B) (ti.com)
Your analog outputs are without amp, see page 40…
Hello Karam,
I have not been able to get the software working on WIN 10/11. However, I think I have another option that should work better.
Since you are using an external reference, connected by cables, this will pickup quite a bit of noise and may be…
Hi Kannon,
Take a look at the EVM User Guide for the IS0224EVM (Figure 6, page 8). There is a differential to single ended circuit example with a gain of 3 so you get the same output voltage as what you apply to the input. For the OPA on the output, you…
Hello Emanuel
I took a look at the schematics and here are few suggestions regarding DAC that I am familiar with:
The filter component value is ok
I would use dedicated decupling capacitors for each supply pin- right at the pin or as close as possible. …
