DIGITAL-TO-ANALOG CONVERTER
Check for Samples: DAC7718 FEATURES DESCRIPTION The DAC7718 is a low-power, octal, 12-bit
digital-to-analog converter (DAC). With a 5V
reference, the output can either be a bipolar В±15V
voltage when operating from dual В±15.5V (or higher)
power supplies, or a unipolar 0V to +30V voltage
when operating from a +30.5V (or higher) power
supply. With a 5.5V reference, the output can either
be a bipolar В±16.5V voltage when operating from dual
В±17V (or higher) power supplies, 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-code and gain error. In addition, system level
calibration can be performed over the entire signal
chain. The output range can be offset by using the
DAC offset register. 1 2345 Bipolar Output: В±2V to В±16.5V …
