CHAPTER 10 12-BIT A/D CONVERTER (μ PD78F150xA),
10-BIT A/D CONVERTER (μ PD78F151xA)
The ANI0/AMP0-/P20 to ANI7/AMP2O/P27, ANI8/AMP2+/P150 to ANI10/P152 and ANI15/AVREFM/P157 pins are as
shown below depending on the settings of ADPC, ADS, PM2, PM15, OAENn bit and ADREF bit.
Caution
When an operational amplifier is used, pins AMPn+, AMPn−, and AMPnO are used, so the
alternative analog input functions cannot be used. The operational amplifier output signals,
however, can be used as analog inputs.
