AD5415 Bipolar Operation In some applications, it may be necessary to generate full 4-quadrant multiplying operation or a bipolar output swing. This can easily be accomplished by using another external amplifier and the on-chip 4-quadrant resistors, as shown in Figure ...
Page 17
Positive Output Voltage The output voltage polarity is opposite to the V dc reference voltages. To achieve a positive voltage output, an applied negative reference to the input of the DAC is preferred over the output inversion through an inverting ...
