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, V
LC
, grounded.
Changing the V
LC
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.
