models), all on one small monolithic chip. A combina-
tion of current-switch design techniques accomplishes
not only 15-bit monotonicity over the entire specified
temperature range, but also a maximum end-point
linearity error of
±0.0015%
of full-scale range. Total
full-scale gain drift is limited to
±10ppm/°C
maximum
(LH and CH grades).

Specification same as model to the left.
NOTES: (1) Digital inputs are TTL, LSTTL, 54/74C, 54/74HC, and 54/74HTC compatible over the operating voltage range of V
DD
= +5V to +15V and over the specified
temperature range. The input switching threshold remains at the TTL threshold of 1.4V over the supply range of V
DD
= +5V to +15V. As logic “0” and logic “1” inputs vary over
0V to +0.8V and +2.4V to +10V respectively, the change in the D/A converter output voltage will not exceed
±0.0015%
of FSR for the LH and CH grades,
±0.003%
of FSR for
the BH grade and
±0.006%
of FSR for the KG grade. (2) DAC702 (current-output models) is specified and tested with an external output operational amplifier connected using
the internal feedback resistor in all parameters except settling time. (3) FSR means full-scale range and is 20V for the
±10V
range (DAC703), 10V for the 0 to +10V range
(DAC701). FSR is 2mA for the
±1mA
range (DAC702). (4)
±0.0015%
of full-scale range is equivalent to 1LSB in 15-bit resolution.
±0.003%
of full-scale range is equivalent to
1LSB in 14-bit resolution.
±0.006%
of full-scale range is equivalent to 1LSB in 13-bit resolution. (5) Adjustable to zero with external trim potentiometer. Adjusting the gain
potentiometer rotates the transfer function around the zero point. (6) Error at input code FFFF
H
for DAC701, 7FFF
H
for DAC702 and DAC703. (7) With gain and zero errors
adjusted to zero at +25°C. (8) Maximum represents the 3σ limit. Not 100% tested for this parameter. (9) At the major carry, 7FFF
H

H

. (10) Tolerance
on output impedance and output current is
±30%.
(11) Power dissipation is an additional 40mW when V
DD
is operated at +15V.
