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
differential output voltages of 20 Vp-p with simple resistor
loads. The reference-to-full-scale current matching of better
than
applications, while the nonlinearities of better than
over temperature minimizes system error accumulations.
The noise immune inputs will accept a variety of logic levels.
The performance and characteristics of the device are es-
sentially unchanged over the
range and power consumption at only 33 mW with
supplies is independent of logic input levels.
The DAC0800, DAC0802, DAC0800C and DAC0802C are a
direct replacement for the DAC-08, DAC-08A, DAC-08C,
and DAC-08H, respectively. For single supply operation,
refer to AN-1525.
