DAC7728 八路、低功耗、12 位 +/-15V 输出并行输入数模转换器
DAC7728 同类产品
DAC7728 说明
The DAC7728 is a low-power, octal, 12-bit digital-to-analog converter (DAC). With a 5V reference, the output can either be a bipolar ±15V voltage when operating from a dual ±15.5V (or higher) power supply, or a unipolar 0V to +30V voltage when operating from a +30.5V power supply. With a 5.5V reference, the output can either be ±16.5V for a dual ±17V (or higher) power supply, or a unipolar 0V to +33V voltage when operating from a +33.5V (or higher) power supply. This DAC provides low-power operation, good linearity, and low glitch over the specified temperature range of –40°C to +105°C. This device is trimmed in manufacturing and has very low zero and full-scale error.
