10.8.1 Enabling the Auxiliary ADC
The Auxiliary ADCs are disabled by default.
Below is the timing diagram illustrating the Aux ADC operation.
Before starting conversion, set bit EN_AUX_ADC to '1'. Also set WHAT_IS_SDOUT<1:0> to configure
SDOUT as a digital output pin.
Figure 10-16. AUX ADC Timing Diagram
Note that throughout the Aux ADC conversion, SEN is kept low (active). Also keep SDATA low once the
CONV_START bit has been written.
To get out of Aux ADC conversion mode, pull SEN high, then pull it low again and write the bit to make
CONV_START=0.
10.9 Auxiliary DAC
The schematic of the Auxiliary DAC (for channel A) is shown below.
Figure 10-17. Auxiliary DAC Schematic
The Auxiliary DAC is a 12-bit current output DAC with the current steered into the AUXDAC_A pin
dependent on the digital code. The data format of the Auxiliary DAC input is offset binary.
REXT is the external connected to the AUXDAC_A pin and along with the value of the full scale current,
sets the full scale output voltage range. For zero input code, voltage on AUXDAC_A is equal to 0 V.
For maximum input code, voltage on AUXDAC_A is equal to IAUX_DAC*REXT.
IAUX_DAC is the full scale current of the Auxiliary DAC, and can be programmed from 2.5 mA to 7.5 mA
(using bits FS_AUXDACI<3:0>).
For best linearity, limit the maximum voltage at AUXDAC_A to 1.5V. For example, with IAUX_DAC set to 5
mA, and REXT set to 300 Ohm, the voltage on AUXDAC_A will swing from 0 to 1.5V.
