TLA2528: AINx Configuration

Part Number: TLA2528

Hello Guys,

We have a customer who plan to use TLA2528  to read 8 different voltages (from 1.0V to 3.3V) on a board. Should the AIN input pin be connected directly to the supply voltage or it needs to be connected to voltage rail thru a resistor network?


Are there any special considerations I need to make for this device?

Thanks to confirm!

    Hello,

    if you are using one of the analog input channels to measure the voltage supply of the ADC, you will need to use a resistor network. This device uses AVDD as the reference, this will provide a ratiometric measurement of the AVDD.

    This device is a very straight forth device, thus no special considerations are needed.

    Regards
