PGA900: about detail datasheet

ACGUY
Guru 11170 points
Part Number: PGA900

Hello E2E,

Q1;
Can I have detail datasheet for PGA900 from web?

Q2;
I have question from our customer.
------
There are two ADC interrupts, PADC_Handler and TADC_Handler,

1st: PADC is enabled and TADC is disabled, PADC conversion is performed by PADC_Handler interrupt and TADC is not performed.

2nd: PADC is disabled and TADC is enabled, PADC_Handler interrupt does not occur and TADC_Handler interrupt does not occur.

3rd: PADC are enabled and TADC is enabled, PADC and TADC are performed by the PADC_Handler interrupt, and no TADC_Handler interrupt is generated.

We'd like to confirmed the above behavior. Is there any way to enable the TADC_Handler interrupt?
-----
Does TI can to answer for this question?

Regards,
ACGUY

    Hello ACGUY,

    To download the full datasheet, you will need to click the link on the PGA900 product page under where it says "More information" you click on "Request Now": http://www.ti.com/product/PGA900 

    The interrupts are generated any time the ADCs complete a conversion. The handlers are just shell functions in the example code which are called once there is an interrupt. The customer will have to write their own firmware for the interrupt handlers. Currently the E2E support model for the PGA900 has changed, and is limited to the documentation available on the PGA900 product page (linked above).

    For more information on the current support model please see this thread: https://e2e.ti.com/support/sensors/f/1023/t/802433

    Regards,
