Digit, A/D Converter
The ICL8052A or ICL8068A/lCL71C03 chip pairs with their
multiplexed BCD output and digit drivers are ideally suited
for the visual display DVM/DPM market. The outstanding

digit accuracy, 200.00mV to 2.0000V full scale
capability, auto-zero and auto-polarity combine with true
ratiometric operation, almost ideal differential linearity and
time-proven dual slope conversion. Use of these chip pairs
eliminates clock feedthrough problems, and avoids the
critical board layout usually required to minimize charge
injection.
When only 2000 counts of resolution are required, the 71C03
can be wired for 3

digits and give up to 30 readings/sec.,
making it ideally suited for a wide variety of applications.
The ICL71C03 is an improved CMOS plug-in replacement for
the lCL7103 and should be used in all new designs.
