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 current 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 ± 1 LSB eliminates the need for full-scale trims in most applications, while the nonlinearities of better than ± 0.1% 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 essentially unchanged over the ± 4.5V to ± 18V power supply range and power consumption at only 33 mW with ± 5V 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.
