... A typical DNL vs. code plot can be seen in Figure 17. Monotonicity A DAC is monotonic if the output either increases or remains constant for increasing digital input code. The AD5725 is monotonic over its full operating temperature range. Full-Scale Error Full-scale error is a measure of the output error when full-scale code is loaded to the DAC register ...

... THEORY OF OPERATION The AD5725 is a quad voltage output, 12-bit parallel input DAC featuring a 12-bit data bus with readback capability. The AD5725 operates from single or dual supplies ranging from + ±15 V. The output voltage range is set by the reference voltages applied at the V and V pins ...

... It does not supply current to the device. If the readback function is not used, V can be left open-circuit. While V L not supply current to the AD5725, it does supply current to the digital outputs when the readback function is used. REFERENCE CONFIGURATION Output voltage ranges can be configured as either unipolar or bipolar, and within these choices, a wide variety of options exists ...
