SEPARATE AGND PINS
The DACs in the AD7537 have separate AGND lines taken to
pins AGNDA and AGNDB on the package. This increases the
applications versatility of the part. Figure 6 is an example of
this. DAC A is connected in standard fashion as a program-
mable attenuator. AGNDA is at ground potential. DAC B is op-
erating with AGND B biased to +5 V by the AD584. This gives
an output range of +5 V to +10 V.

PROGRAMMABLE OSCILLATOR
Figure 7 shows a conventional state variable oscillator in which
the AD7537 controls the programmable integrators. The fre-
quency of oscillation is given by:

C1
×C2× REQ1× REQ2
where REQ1 and REQ2 are the equivalent resistances of the
DACs. The same digital code is loaded into both DACs.
If C1 = C2 and R5 = R6, the expression reduces to

where m is the DAC ladder resistance mismatch ratio, typically

With the values shown in Figure 7, the output frequency varies
from 0 Hz to 1.38 kHz. The amplitude of the output signal at
the A3 output is 10 V peak-to-peak and is constant over the
entire frequency span.
