AD7190 & AD7192 Channel Issue

Dear Analog Devices Community,

 

My application using AIN3 as in+ and AIN4 as in-.

 

The Mode Register I use the default value, the Configuration Register I write into the chip is 0x000217.

 

But when I check the status register, it always shows 0x80 which indicate the converted data is from channel 0 despite I performed several times of single data read.

 

Sorry to say that I am really new and still blur about how to fully control the ADC chip, hope that some expert can teach me on this.

 

Thanks in advance.

 

Regard,

Sky Lee
