Analog-to-Digital Converter
Architecture
PS022825-0908
The analog-to-digital converter (ADC) converts an analog input signal to its digital repre-
sentation. The features of this sigma-delta ADC include:

network selects the ADC input from the available analog pins, ANA0 through ANA7.
The input stage of the ADC allows both differential gain and buffering. The following
input options are available:
•

11-bit resolution in DIFFERENTIAL mode.
10-bit resolution in SINGLE-ENDED mode.
Eight single-ended analog input sources are multiplexed with general-purpose I/O
ports.
9
11 pairs of differential inputs also multiplexed with general-purpose I/O ports.
Low-power operational amplifier (LPO).
Interrupt on conversion complete.
Bandgap generated internal voltage reference with two selectable levels.
Manual in-circuit calibration is possible employing user code (offset calibration).
Factory calibrated for in-circuit error compensation.
Unbuffered input (SINGLE-ENDED and DIFFERENTIAL modes).
Buffered input with unity gain (SINGLE-ENDED and DIFFERENTIAL modes).
LPO output with full pin access to the feedback path.
