10. 10-Bit ADC (ADC0)
ADC0 on the C8051F700/2/4/6/8 and C8051F710/2/4/6 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 pro-
grammable window detector. The ADC is fully configurable under software control via Special Function
Registers. The ADC may be configured to measure various different signals using the analog multiplexer
described in Section “10.5. ADC0 Analog Multiplexer” on page 65. The voltage reference for the ADC is
selected as described in Section “11. Temperature Sensor” on page 67. 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.
