CHAPTER 12 OPERATIONAL AMPLIFIER (μ PD78F150xA only)
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.

Remark 78K0R/LF3:
78K0R/LG3, 78K0R/LH3:
ANI0/AMP0-/P20, ANI2/AMP0+/P22, ANI3/AMP1-/P23,
ANI5/AMP1+/P25, n = 0, 1
ANI0/AMP0-/P20, ANI2/AMP0+/P22, ANI3/AMP1-/P23,
ANI5/AMP1+/P25, ANI6/AMP2-/P26, ANI8/AMP2+/P150, n = 0 to 2
Caution When an operational amplifier is used, AMPn+, AMPnâ, and AMPnO pins are used, so the alternative
analog input functions cannot be used.
