Hi,

In the datasheet of TPA6133A2, gain is mentioned as fixed. Is there any way to increase the gain of TPA6133A2?

Hi Divya,

The gain of this device is set by internal arrange of input and feedback resistors (fixed). So changing the gain would not be feasible.

Just an additional note, there is TPA6130A2 which is similar to TPA6133A2 with adjustable gain through I2C control.
