D/A CONVERTER APPLICATIONS
The AD712 is an excellent output amplifier for CMOS DACs.
It can be used to perform both 2 quadrant and 4 quadrant op-
eration. 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 for codes containing all zero,
the output impedance is infinite.
For example, the output resistance of the AD7545 will modu-
late between 11 k
Ω and 33 kΩ. Therefore, with the DAC’s
internal feedback resistance of 11 k
Ω, the noise gain will vary
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 AD712K with guaranteed 700
µV offset voltage minimizes
this effect to achieve 12-bit performance.
Figures 31 and 32 show the AD712 and AD7545 (12-bit
CMOS DAC) configured for unipolar binary (2-quadrant multi-
plication) or bipolar (4-quadrant multiplication) operation.
Capacitor C1 provides phase compensation to reduce overshoot
and ringing.
