signed to interface to an 8-bit microprocessor bus. 16-
bit data is loaded in two successive 8-bit bytes into
parallel 8-bit latches before being transferred into the
D/A latch. The DAC708 and DAC709 are current and
voltage output models respectively and are in 24-pin
hermetic DIPs. Input coding is Binary Two’s Comple-
ment (bipolar) or Unipolar Straight Binary (unipolar,
when an external logic inverter is used to invert the
MSB). In addition, the DAC708/709 can be loaded
serially (MSB first).
The DAC707 is designed to interface to a 16-bit bus.

Data is written into a 16-bit latch and subsequently the
D/A latch. The DAC707 has bipolar voltage output
and input coding is Binary Two’s Complement (BTC).
All models have Write and Clear control lines as well
as input latch enable lines. In addition, DAC708 and
DAC709 have Chip Select control lines. In the bipolar
mode, the Clear input sets the D/A latch to give zero
voltage or current output. They are all 14-bit accurate
and are complete with reference, and for the DAC707,
and DAC709, a voltage output amplifier. All models
are available with an optional burn-in screening.

NOTES: (1) MSB must be inverted externally prior to DAC708/709 input. (2) Digital inputs are TTL, LSTTL, 54/74C, 54/74HC and 54/74HTC compatible over the specified
temperature range. (3) DAC708 (current-output models) are specified and tested with an external output operational amplifier connected using the internal feedback
resistor in all tests. (4) FSR means Full Scale Range. For example, for
±10V
output, FSR = 20V. (5)
±0.0015%
of Full Scale Range is equal to 1 LSB in 16-bit resolution,
±0.003%
of Full Scale Range is equal to 1 LSB in 15-bit resolution.
±0.006%
of Full Scale Range is equal to 1 LSB in 14-bit resolution. (6) Error at input code 0000
H
.
(For unipolar connection on DAC708/709, the MSB must be inverted externally prior to D/A input.) (7) Adjustable to zero with external trim potentiometer. Adjusting the
gain potentiometer rotates the transfer function around the bipolar zero point. (8) With gain and zero errors adjusted to zero at +25°C. (9) Maximum represents the 3σ
limit. Not 100% tested for this parameter. (10) The bipolar worst-case code change is FFFF
H
to 0000

and 0000
