OBSOLETE _{GENERAL DESCRIPTION}
The MDA-10Z and DAC-10Z are low cost, lO-bit di~ital-to-
analog 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.
Note that the DAC-10Z-1 requires no external gain or zero
adjustment. The DAC-10Z-3 requires a 1kil offset adjust-
ment 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.

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.
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.
