Analog I/O 0 (AIO0)
The PAC2514X has an AIO0 module and pin that includes a gain amplifier for analog I/O. The
AIO0 pin can be configured as an input to the amplifier with the output of the gain amplifier,
AIO0A, routed to the AFE Mux for input to the MCU ADC. Or the AIO0 pin can be configured to
output internal signals of the AFE. The following signals are available for output on the AIO0
pin:
•
ADCVREF
–
2.5V Voltage Reference
•
AFEMUXOUT
–
AFE Mux Output to the MCU ADC
•
IMUXOUT
–
Current Mux Output to the Current ADC
•
VBMUXOUT
–
Battery Cell Voltage Mux Output to the Voltage ADC
