CMOS DAC APPLICATIONS
The AD713 is an excellent output amplifier for CMOS DACs. It
can be used to perform both two- and four-quadrant operation.
The output impedance of a DAC using an inverted R-2R ladder
approaches R for codes containing many 1s, 3R for codes
containing a single 1, and infinity for codes containing all 0s.
For example, the output resistance of the AD7545 modulates
between 11 kΩ and 33 kΩ. Therefore, with the DAC’s internal
feedback resistance of 11 kΩ, the noise gain varies from 2 to
4/3. This changing noise gain modulates the effect of the input
offset voltage of the amplifier, resulting in nonlinear DAC
amplifier performance. The AD713, with its guaranteed 1.5 mV
input offset voltage, minimizes this effect, achieving 12-bit
performance.

FILTER APPLICATIONS
A Programmable State Variable Filter
For the state variable or universal filter configuration of Figure 44
to function properly, DAC A1 and DAC B1 must control the
gain and Q of the filter characteristic, and DAC A2 and DAC B2
must accurately track for the simple expression of fC to be true.
This is readily accomplished using two AD7528 DACs and one
AD713 quad op amp. Capacitor C3 compensates for the effects
of op amp gain bandwidth limitations.
DAC, the AD7545, configured for either a unipolar binary (two-
quadrant multiplication) or bipolar (four-quadrant multiplication)
operation. Capacitor C1 provides phase compensation, which
reduces overshoot and ringing.
Table 5. Recommended Trim Resistor Values vs. Grades for
AD7545 for VD = 5 V
This filter provides low-pass, high-pass, and band-pass outputs
and is ideally suited for applications where microprocessor
control of filter parameters is required. The programmable
range for component values shown is fC = 0 kHz to 15 kHz and
Q = 0.3 to 4.5.
