ADC
8.1 General description
The P89LPC952/954 has a 10-bit, 8-channel multiplexed successive approximation ADC
module. A block diagram of the ADC is shown in Figure 17. The ADC consists of an
8-input multiplexer which feeds a sample-and-hold circuit providing an input signal to one
of two comparator inputs. The control logic in combination with the SAR drives a DAC
which provides the other input to the comparator. The output of the comparator is fed to
the SAR.
8.2 Features
I 10-bit, 8-channel multiplexed input, successive approximation ADC.
I Eight result register pairs.
I Six operating modes:
N Fixed channel, single conversion mode.
N Fixed channel, continuous conversion mode.
N Auto scan, single conversion mode.
N Auto scan, continuous conversion mode.
N Dual channel, continuous conversion mode.
N Single step mode.
I Three conversion start modes:
N Timer triggered start.
N Start immediately.
N Edge triggered.
I 10-bit conversion time of 4 s at an A/D clock of 9 MHz.
I Interrupt or polled operation.
I High and low boundary limits interrupt; selectable in or out-of-range.
I Clock divider.
I Power-down mode.
