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 40C to +105C. This device is trimmed in manufacturing and has very low zero and full-scale error. In addition, user calibration can be performed over the entire signal chain. The output range can be offset by using the DAC Offset Register.
