General description
The P89LPC924/925 has an 8-bit, 4-channel multiplexed successive approximation
analog-to-digital converter module. A block diagram of the A/D converter is shown in
Figure 5. The A/D consists of a 4-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 successive approximation register (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.
