Analog-to-Digital Converter
Architecture
Operation
PS025011-1010
The Z8 Encore! includes an eight-channel Successive Approximation Register Analog-to-
Digital converter (SAR ADC). The ADC converts an analog input signal to a 10-bit binary
number. The features of the ADC include:
•

The ADC architecture
sample-and-hold amplifier, and 10-bit SAR ADC. The ADC digitizes the signal on a
selected channel and stores the digitized data in the ADC data registers. In environments
with high electrical noise, an external RC filter must be added at the input pins to reduce
high-frequency noise.
The ADC converts the analog input, ANA
equation for calculating the digital value is calculated by:
Assuming zero gain and offset errors, any voltage outside the ADC input limits of AV
and V
A new conversion can be initiated by software write to the ADC Control Register’s
bit. Initiating a new conversion stops any conversion currently in progress and begins a
new conversion. To avoid disrupting a conversion already in progress, the
be read to indicate ADC operation status (busy or available).
Eight analog input sources multiplexed with general-purpose I/O ports
Fast conversion time, less than 4.9 µs
Programmable timing controls
Interrupt on conversion complete
Internal 1.6 V voltage reference generator
Internal reference voltage available externally
Ability to supply external reference voltage
