DAC0800/DAC0802
8-Bit Digital-to-Analog Converters
General Description
The DAC0800 series are monolithic 8-bit high-speed
current-output digital-to-analog converters (DAC) featuring
typical settling times of 100 ns. When used as a multiplying
DAC, monotonic performance over a 40 to 1 reference cur-
rent range is possible. The DAC0800 series also features
high compliance complementary current outputs to allow dif-
ferential output voltages of 20 Vp-p with simple resistor loads
as shown in Figure 1. The reference-to-full-scale current
matching of better than ±1 LSB eliminates the need for
full-scale trims in most applications while the nonlinearities
of better than ±0.1% over temperature minimizes system er-
ror accumulations.
The noise immune inputs of the DAC0800 series will accept
TTL levels with the logic threshold pin, VLC, grounded.
Changing the VLC potential will allow direct interface to other
logic families. The performance and characteristics of the
device are essentially unchanged over the full ±4.5V to
±18V power supply range; power dissipation is only 33 mW
with ±5V supplies and is independent of the logic input
states.
The DAC0800, DAC0802, DAC0800C and DAC0802C are a
direct replacement for the DAC-08, DAC-08A, DAC-08C,
and DAC-08H, respectively.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
Note 3: The maximum junction temperature of the DAC0800 and DAC0802 is 125˚C. For operating at elevated temperatures, devices in the Dual-In-Line J package
must be derated based on a thermal resistance of 100˚C/W, junction-to-ambient, 175˚C/W for the molded Dual-In-Line N package and 100˚C/W for the Small Outline
M package.
Note 4: Human body model, 100 pF discharged through a 1.5 kresistor.
Note 5: Pin-out numbers for the DAC080X represent the Dual-In-Line package. The Small Outline package pin-out differs from the Dual-In-Line package.
