8.2 Features and benefits
temperature. The temperature sensor is measured through Anin03. Anin00, Anin01 and
Anin02 are unused. A block diagram of the ADC is shown in
diagram”.
The ADC consists of an 4-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.
8-bit, 4-channel multiplexed input, successive approximation ADC.
