A/D Converter
The C868 includes a high performance / high speed 8-bit A/D-Converter (ADC) with 5
analog input channels. It operates with a successive approximation technique and uses
self calibration mechanisms for reduction and compensation of offset and linearity errors.
The A/D converter provides the following features:
– 5 multiplexed input channels, which can also be used as digital inputs
– 8-bit resolution with TUE of +/- 2 LSB8.
– Single or continuous conversion mode
– Interrupt request generation after each conversion
– Using successive approximation conversion technique via a capacitor array
– Built-in calibration of offset and linearity errors
– Powerdown in normal, idle and slow-down modes
