Description of DAC0800 8 Bit D/A Converter 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. Features Fast settling output current: 100 ns Full scale error: ±1 LSB Nonlinearity over temperature: ±0.1% Full scale current drift: ±10 ppm/°C High output compliance: −10V to 18V Complementary current outputs Interface directly with TTL, CMOS, PMOS and others 2 quadrant wide range multiplying capability Wide power supply range: ±4.5V to ±18V Low power consumption: 33 mW at ±5V Low cost
