DAC0802

DAC0800/DAC0802 8-Bit Digital-to-Analog Converters June 1999 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 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 error 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.
