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

• Accuracy Guaranteed to 1 Count Over Entire 20,000

Counts (2.0000V Full Scale)

4 / 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.

• Guaranteed Zero Reading for 0V Input

• True Polarity at Zero Count for Precise Null Detection

• Single Reference Voltage Required

• Over-Range and Under-Range Signals Available for Auto-

Ranging Capability

When only 2000 counts of resolution are required, the 71C03

• All Outputs TTL Compatible

can be wired for 3 / digits and give up to 30 readings/sec.,

making it ideally suited for a wide variety of applications.

• Medium Quality Reference, 40ppm (Typ) on Board

• Blinking Display Gives Visual Indication of Over Range

The ICL71C03 is an improved CMOS plug-in replacement for

the lCL7103 and should be used in all new designs.
