C8051F80x-83x
8. 10-Bit ADC (ADC0)
ADC0 on the C8051F800/1/2/3/4/5, C8051F812/3/4/5/6/7, C8051F824/5/6, and C8051F830/1/2 is a
500 ksps, 10-bit successive-approximation-register (SAR) ADC with integrated track-and-hold, a gain
stage programmable to 1x or 0.5x, and a programmable window detector. The ADC is fully configurable
under software control via Special Function Registers. The ADC may be configured to measure various dif-
ferent signals using the analog multiplexer described in Section “8.5. ADC0 Analog Multiplexer” on
page 56. The voltage reference for the ADC is selected as described in Section “9. Temperature Sensor”
on page 58. The ADC0 subsystem is enabled only when the AD0EN bit in the ADC0 Control register
(ADC0CN) is set to logic 1. The ADC0 subsystem is in low power shutdown when this bit is logic 0.
