P89LPC9381
8-bit microcontroller with 10-bit ADC
providing an input signal to one of two comparator inputs. The control logic in combination
with the SAR drives a digital-to-analog converter 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 ADC 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
