ICL8052/ICL71C03,

ICL8068/ICL71C03

August 1997

Precision 4 / Digit, A/D Converter

Features

Description

• Typically Less Than 2µV

Scale, lCL8068)

Noise (200.00mV Full

The ICL8052 or ICL8068/lCL71C03 chip pairs with their

multiplexed BCD output and digit drivers are ideally suited

P-P

for the visual display DVM/DPM market. The outstanding

4 / digit accuracy, 200.00mV to 2.0000V full scale capabil-

ity, 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.

• Accuracy Guaranteed to ±1 Count Over Entire ±20,000

Counts (2.0000V Full Scale)

• Guaranteed Zero Reading for 0V Input

• True Polarity at Zero Count for Precise Null Detection

• Single Reference Voltage Required

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

• Over-Range and Under-Range Signals Available for

Auto-Ranging Capability

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

making it ideally suited for a wide variety of applications.

• All Outputs TTL Compatible

The ICL71C03 is an improved CMOS plug-in replacement for

the lCL7103 and should be used in all new designs.

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

• Blinking Display Gives Visual Indication of Over

Range
