DAC0800/DAC0801/DAC0802 8-Bit Digital-to-Analog Converters
DAC0800 series monolithic 8-bit high-speed current-output digital-to-analog converters (DAC) featuring typical settling times When used multiplying DAC, monotonic performance over reference current range possible. DAC0800 series also features high compliance complementary current outputs allow differential output voltages Vp-p with simple resistor loads shown Figure reference-to-full-scale current matching better than eliminates need full-scale trims most applications while nonlinearities better than 0.1% over temperature minimizes system error accumulations. noise immune inputs DAC0800 series will accept levels with logic threshold pin, VLC, grounded. Changing potential will allow direct interface other logic families. performance characteristics device essentially unchanged over full 4.5V power supply range; power dissipation only with supplies independent logic input states. DAC0800, DAC0802, DAC0800C, DAC0801C DAC0802C direct replacement DAC-08, DAC-08A, DAC-08C, DAC-08E DAC-08H, respectively.
Features
Fast settling output current: Full scale error: Nonlinearity over temperature: 0.1% Full scale current drift: ppm/°C High output compliance: -10V +18V Complementary current outputs Interface directly with TTL, CMOS, PMOS others quadrant wide range multiplying capability Wide power supply range: 4.5V power consumption: cost
