Hello Shraddha,

Before you can read through I2C you will have to place the PGA305 in reset mode so that the digital interfaces can access the registers. You will write 0x03 to register 0x0C in page 0.

The command is 0x40 0x0C 0x03

Regards,

I have done that setting already . It is compensation control register. I still dont get any thing from the above mentioned register .
