GENERAL Dr'.SC.'ltIrrl1ON
The HDS/IIDH series of digital to analog converters represent
the fastest precision settling current and voltage DAC's avail-
able. Capable ofprocessing to MIL-STD-883 and guaranteed
monotonicity over their operating temperature range; their
quiescent power is 1/2 that of competitive units. The current
output models provide lOmA full scale allowing direct drive
of capacitive loads and transmission lines. All versions have a
precision reference and arc active laser trimmed to specified
accuracy, thus no external adjustment pots or other compo-
nents are required.
With 6 available units engineering trade-offs can be made be-
tween resolution, speed, current or voltage output, and of
course price. To facilitate this comparison major specifications
are summarized in Table I.

Other general specifications that apply to all devices include
T'I'L logic; glass or hermetic metal package; unipolar or bi-
polar operation with internal offsetting reference.
The HDH voltage on tput devices provide access to the op amp
summing point so that reduced full scale output voltage swing
can be provided. Such operation with an external resistor
shunting the internal 1k resistor will reduce the already low
op amp offset drift.

2 For HDS series, VOUT = IOUT X “equivalcnt which is the value of the
20012 internal impedance in parallel With the external load resistance.
Thus, by correct selection of cxlcmal R1 VOUT can be any magnitude
up to the f or - compliance voltage. See Figures 1 and 2.
