User’s Manual 55
Reads the state of a single-ended A/D converter input channel and uses the previously set calibration
constants to convert it to volts.
If the gain code for a given channel has changed from the previous cycle, the following code accesses
will occur.
1. The EEPROM will be read to get the calibration constants for the new gain value.
2. The D/A converter will be written to bias the A/D converter input circuit for proper operation. (The
D/A converter access only applies for the single-ended bipolar A/D converter operation.)
PARAMETER
channel
is the A/D converter input channel (0–7).
gaincode is the gain code of 0 to 7.
RETURN VALUE
A voltage value corresponding to the voltage on the analog input channel. A value of -4096 indicates an
overflow or out-of-range condition.
