Product data sheet
8.2 Features and benefits
The ADC consists of an 8-input multiplexer which feeds a sample-and-hold circuit
providing an input signal to 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.
10-bit, 8-channel multiplexed input, successive approximation ADCs. (10-bit,
4-channel on P89LPC983)
Eight result register pairs.
Six operating modes:
Three conversion start modes:
10-bit conversion time of 5 μs at an A/D clock of 6.6 MHz.
Interrupt or polled operation.
