5.2.3 Bipolar Operation ±5 V<br />
Analog Outputs<br />
Prerequisite for a bipolar operation with ±5 V is the correct configuration of the board via the jumpers<br />
(J300 for all channels together and two of jumpers J400...J731 for the according channel)!<br />
For the output voltage range ±5 V the converter components DAC813 require the data in 'BTC' (Binary<br />
Two's Complement) format. The following table shows the assignment of data to output voltages for<br />
this format by means of some basic data.<br />
Input<br />

Output<br />
111111111111 - 1 LSB (- 0.0024 V)<br />
100000000000 - maximum value (- 5.000 V)<br />
011111111111 + maximum value (+ 4.9975 V)<br />
000000000000 null (0.0000 V)<br />
