TPA3111D1: About INP and INP pin

Part Number: TPA3111D1

Hi,

Could you tell me about INN and INP pin?
Customer wants to set the gain to ”×5” by connecting a resistor to INN and INP pins.
In this way Can you use the TPA3111D1?



Best Regards,
Yusuke / Japan Disty

    Yusuke-San,

    Please review section (7.3.1 Gain Setting Through GAIN0 and GAIN1 Inputs) of the datasheet. It describes how to set the device gains.

    You cannot set the gain using external connection to the INN and INP pins.

    Regards,
