The MC68HC11F1 analog-to-digital (A/D) converter system uses an all-capacitive charge-redistribution
technique to convert analog signals to digital values. The A/D system is an 8-channel, 8-bit, multiplexed-
input, successive-approximation converter, accurate to 1 least significant bit (LSB). Because the ca-
pacitive charge redistribution technique used includes a built-in sample-and-hold, no external sample-
and-hold is required.
Dedicated lines V
rates of 750 kHz or below must use an internal RC oscillator. The CSEL bit in the OPTION register se-
lects the clock source for the A/D system. (The CSEL bit is described in 11.3 A/D Registers, page 56.)
A multiplexer allows the single A/D converter to select one of 16 analog signals, as shown in Table 24.
