Part Number: ADS7038-Q1

Hello,

What is the TI recommendation for AINx analog input pin if not used?

To pull up or pull down?

    Hi Vishwas,

    The primary expert is out of office this week. Please expect delays on replies and answers.

    Usually, the recommendation is to ground the inputs (through pull down is acceptable), or float them. I personally not familiar with this device so we need to contact the primary expert to confirm. Please expect a response in a week.

    Best,

    -Cole

    Vishwas,

    I agree with Cole.  It is not necessary to use a pull down resistor.  You can simply connect the pin to GND or float.
