R A =R B =50 ? , R DIFF =100 ? , assuming R LOAD =50 ? . The
performance of Figure 13 and Figure 14 is basically the
same, however leaving the center tap of Figure 14 floating

allows the circuit to find a more balanced virtual ground,
theoretically improving the even order harmonic rejection,

but likely reducing the signal swing available due to the
output voltage compliance range limitations.

OUTB
The converter requires two clock rising edges for data to be
represented at the output. Each rising edge of the clock
captures the present data word and outputs the previous

processing. See Figure 15.
Test Service
Intersil offers customer-specific testing of converters with a
service called Testdrive. To submit a request, fill out the
