3.6 D/A Converter Outputs
Only the BL2100 and the BL2120 models are stuffed with D/A converters. The D/A con-
verter outputs are buffered and scaled to provide an output from 0 V to +10 V.
NOTE: The D/A converter output voltage depends on the original power-supply voltage,
+RAW, so if +RAW < 13 V, the maximum D/A converter output will be +RAW – 3 V.
Figure 19 shows the D/A converter outputs.

Figure 19. D/A Converter Outputs
To stay within the maximum power dissipation of the D/A converter circuit, the maximum
D/A converter output current is 10 mA per channel for a power-supply voltage, +RAW, up
to 15 V, and drops to 2 mA per channel for a power-supply voltage of 36 V.

Current vs. Power-Supply Voltage
The D/A converter inputs are factory-calibrated and the calibration constants are stored in
flash memory. You may calibrate the A/D converter inputs at a later time using the software
functions described in Section 4.4.5, “D/A Converter Outputs.” The GETCALIB.C and
the SAVECALIB.C sample programs in the Dynamic C SAMPLES\BL2100\
Calib_Save_Retrieve folder illustrate how to retrieve and save calibration data.
