TLV4316-Q1: Issue in TLV4316 IC

Tool/software:

Hi Team,

We are using this IC in our project and facing an issue where we are getting a 1.8V output even without providing any input to PWM_INPUT_P and PWM_INPUT_N in the attached schematic. Please verify it.

    You should NOT apply PWM signal directly to the negative input terminal with the positive input grounded as this will result in output slammed against the rail.  Additionally, you should add 0.6pF feedback caps across all 100k feedback resistors to properly compensate the circuit - see below.  

    It is difficult to read your schematic. If you need further assistance, please show one channels under specific conditions.
