10-Bit A/D Converter
The C505L includes a high performance / high speed 10-bit A/D-Converter (ADC) with 8 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:
– 8 multiplexed input channels (port 1), which can also be used as digital inputs/outputs
– 10-bit resolution
– Single or continuous conversion mode
– Internal start-of-conversion trigger capability
– Interrupt request generation after each conversion
– Using successive approximation conversion technique via a capacitor array
– Built-in hidden calibration of offset and linearity errors
The 10-bit ADC uses two clock signals for operation: the conversion clock
f
ADC
(= 1/
t
ADC
) and the
input clock
f
IN
(= 1/
t
IN
).
f
ADC
is derived from the C505L system clock
f
OSC
which is applied at the
XTAL pins. The input clock
f
IN
is equal to
f
OSC
The conversion
f
ADC
clock is limited to a maximum
frequency of 2 MHz. Therefore, the ADC clock prescaler must be programmed to a value which
assures that the conversion clock does not exceed 2 MHz. The prescaler ratio is selected by the
bits ADCL1 and ADCL0 of SFR ADCON1.
