DAC0800/DAC0802
8-Bit Digital-to-Analog Converters
The DAC0800, DAC0802, DAC0800C and DAC0802C are a
direct replacement for the DAC-08, DAC-08A, DAC-08C,
and DAC-08H, respectively.
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

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
