PGA970: PWM digital interface

PY (Pengyu) Song

Part Number: PGA970

Hi team,

In description section of PGA970 datasheet, there is a sentence "External system communication is achieved by using any of the SPI, OWI, GPIO, or PWM digital interfaces."

Is the PWM interface still available? There is no other portion throughout the datasheet discussing the PWM interface.

Hello PY,

I'm getting some additional information on this internally, and I plan to get back to you by the end of the week with some more detail.

Regards,

Hello PY,

I got some feedback a little faster than expected. There is actually no support for hardware driven PWM interface in the PGA970, and this is an error in the datasheet that will be corrected on the next revision.

The only option available would be to use control one of the GPIOs through firmware to achieve a similar output.
