ADuC7060/ADuC7061  adc

Yes, as explained in your previous thread

aduc7060/1 adc max input common mode voltage?

In combination with the OP-AMP you need to tie the Vin- to AGND - this is only possible for the AUX ADC channels if you bypass the negative buffer input.

Bit 2-3 of ADC1CON or if the PRIMARY ADC is used at GAIN 1 automatically.

Please do me a favor - do not open a further new discussion on the same topic

Thanks

In differential mode,you mean is   ADC1 can into  AGND ? (ADC0/ADC1 differential mode)  .

My English is not good, so please understand.
I do pressure transmitter (4-20mA), as power consumption, can not be used ADUC7060 internal amplification.

Sensor 5V power supply bridge mode, the output common-mode voltage 2.5V, the maximum signal is 7mV.

Signal amplification can help deal with me?

Before I used the kind of attachment method
I have bought a 1000 ada4051-2

But input voltage error.
