The operational amplifiers 0 and 1 have the following mode.
• Single AMP mode (operational amplifiers 0 and 1)
• PGA (Programmable gain amplifier) mode (operational amplifier 0 only)
Operational amplifiers 0 and 1 both have two input pins (the AMPn- pin and the AMPn+ pin) and one output pin (the
The amplified voltage can be used as an analog input of the A/D converter, because the AMPnOUT pin is alternatively
The procedure for starting operation in single amplifier mode is described below.
<1> Use the ADPCn register to set the pins (AMPn−, AMPn+, AMPnOUT) to be used in single amplifier mode as
<2> Use the PMx register to set the pins (AMPn−, AMPn+, AMPnOUT) to be used in single amplifier mode to input
<3> Set (1) the OPAMPnE bit and enable operation in single amplifier mode.
Caution To use as an input of the A/D converter a voltage that has been amplified in single amplifier mode,
Remark Products with operational amplifier of the 78K0/KY2-L and 78K0/KA2-L: n = 0, x = 2
In this mode, the analog voltage input from the PGAIN pin is amplified within the microcontroller. The gain can be
The amplified voltage can be used as an analog input of the A/D converter.
The procedure for starting operation in PGA mode is described below.
<1> Use the ADPC0 register to set the pins (PGAIN) to be used in PGA mode as analog I/O.
<2> Use the PM2 register to set the pins (PGAIN) to be used in PGA mode to input mode.
<3> Use the AMP0VG0 and AMP0VG1 bits to select the gain ( 4,
