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

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

• 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.
