Features  
Converters  
• Guaranteed Zero Reading for 0V Input on All Scales  
True Polarity at Zero for Precise Null Detection  
• 1pA Typical Input Current  
The Intersil ICL7106 and ICL7107 are high performance, low  
1
power, 3 / digit A/D converters. Included are seven  
2
segment decoders, display drivers, a reference, and a clock.  
The ICL7106 is designed to interface with a liquid crystal  
display (LCD) and includes a multiplexed backplane drive;  
the ICL7107 will directly drive an instrument size light  
emitting diode (LED) display.  
True Differential Input and Reference, Direct Display Drive  
- LCD ICL7106, LED lCL7107  
• Low Noise - Less Than 15µV  
P-P  
• On Chip Clock and Reference  
The ICL7106 and ICL7107 bring together a combination of  
high accuracy, versatility, and true economy. It features auto-  
zero to less than 10µV, zero drift of less than 1µV/ C, input  
• Low Power Dissipation - Typically Less Than 10mW  
• No Additional Active Circuits Required  
• Enhanced Display Stability  
o
bias current of 10pA (Max), and rollover error of less than  
one count. True differential inputs and reference are useful in  
all systems, but give the designer an uncommon advantage  
when measuring load cells, strain gauges and other bridge  
type transducers. Finally, the true economy of single power  
supply operation (ICL7106), enables a high performance  
panel meter to be built with the addition of only 10 passive  
components and a display.  
• Pb-Free Plus Anneal Available (RoHS Compliant)

1. “R” indicates device with reversed leads for mounting to PC board underside. “S” indicates enhanced stability.  
2. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate  
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are  
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.  
3. Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
