APPLICATIONS
The AD7304/AD7305 are inherently 2-quadrant multiplying
DACs. That is, they can easily be set up for unipolar output
operation. The full-scale output polarity is the same as the
reference input voltage polarity.
In some applications, it may be necessary to generate the full
4-quadrant multiplying capability or a bipolar output swing.
This is easily accomplished using an external true rail-to-rail op
amp, such as the OP295. Connecting the external amplifier with
two equal value resistors, as shown in Figure 38, results in a full
4-quadrant multiplying circuit. In this circuit, the amplifier
provides a gain of two, which increases the output span
magnitude to 10 V. The transfer equation of this circuit shows
that both negative and positive output voltages are created as
the input data (D) is incremented from code zero (VOUT = –5 V)
to midscale (VOUT = 0 V) to full scale (VOUT = +5 V).
