We are using ADUC7061 minikit configured primary ADC as single ended .

  1. 1. In datasheet ADC0/ADC5 (single-ended mode). What is the use of ADC5 pin.

And also says Single-ended channels are selected with respect to ADC5.

Bias ADC5 to a minimum level of 0.1 V.


  1. 2. I had connected ADC5 and ADC0 pin then adc result 0x00000, If I had connected ADC5 to

gnd ( 0V ) and ADC0 to gnd ADC results 30 000 counts , how to change it to expected count?


  1. 3. What is the use of  Bias ADC5 to a minimum level of 0.1 V ?.


  1. For external reference I had used VREF+ and Vref- , and says 2.625 v maximum reference input .

Then for external reference high reference (HIGHEXTREF1) bit need to set causes   Vref /2.

I’am having a (0-5)V process control how can I interface 0- 5V external reference?.

What is the maximum external reference can be given to ADC?.


  1. How to set zero offset or zero count
