The MDA-10Z is a current output device intended for use with external output amplifiers. It featUres a settling time to ::t'lzLSBof 300ns. The DAC-10Z which comes complete with an IC op amp produces voltage outputs with S1JSsettling times. Both the DAC-lOZ and MDA-10Z can be ordered with either unipolar or bipolar outputs. Unipolar units utilize Binary coded inputs and bipolar units use Offset Binary code. All digital inputs are fully TTL/DTL compatible. DAC-10Z OUTPUT CHARACTERISTICS The output circuit configuration as well as the input-output relationships of the DAC-10Z are shown below in Figure 1 for both the unipolar and bipolar output versions. .w"...~",. 1I ~;;:;~+,I, ~ .~ 1--' ~,~ ~, ~ w_:-, . , ~.

MDA-10Z With External Amplifier (Inverting Mode) The gain of the MDA-10Z-2S is adjusted by means of a sooil trim pot which the user supplies. With a digital input of 1111111111 applied, this pot is adjusted until an output of -9.990V is obtained within ::t1mV. ( [1':::'1 TE Note that the DAC-10Z-1 requires no external gain or zero adjustment. The DAC-10Z-3 requires a 1kil offset adjustment pot, which the user must supply. With a digital input of 0000000000 applied, this pot is adjusted until an output of +10.000V is obtained within ::t2mV. In addition to the gain adjustment, the MDA-lOZ-110 requires a zero adjustment. With a digital input of 0000000000 applied, the 1kil offset pot is adjusted until a +10.000V output is obtained within ::t2mV. Next, a digital input of 1111111111 is applied and the 1kil gain pot is adjusted until an output of -9.980V results within ::t2mV. b} Bipolar - DAC-10Z-3 Figure 1.
