GENERAL DESCRIPTION
The MDA-10Z and DAC-10Z are low cost, lO-bit di~ital-toanalog converters packaged in compact 2" x 2" x 0.4' modules.
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.

Figure 2. 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.

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.
