DATASHEET ICL7106, ICL7107, ICL7107S FN3082 Rev 9.00 31/2 Digit, LCD/LED Display, A/D Converters October 24, 2014 The Intersil ICL7106 and ICL7107 are high performance, low Features 1 power, 3 / digit A/D converters. Included are seven segment 2 Guaranteed zero reading for 0V input on all scales decoders, display drivers, a reference, and a clock. The ICL7106 is designed to interface with a liquid crystal display True polarity at zero for precise null detection (LCD) and includes a multiplexed backplane drive the ICL7107 1pA typical input current will directly drive an instrument size light emitting diode (LED) True differential input and reference, direct display drive display. - LCD ICL7106, LED lCL7107 The ICL7106 and ICL7107 bring together a combination of high accuracy, versatility, and true economy. It features Low noise - less than 15V P-P auto zero to less than 10V, zero drift of less than 1V/C, On-chip clock and reference input bias current of 10pA (max) and rollover error of less than Low power dissipation - typically less than 10mW one count. True differential inputs and reference are useful in all systems, but give the designer an uncommon advantage No additional active circuits required when measuring load cells, strain gauges and other bridge Enhanced display stability type transducers. Finally, the true economy of single power Pb-free (RoHS compliant) supply operation (ICL7106), enables a high performance panel meter to be built with the addition of only 10 passive components and a display.

S indicates enhanced stability. 2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate plus anneal (e3 termination finish, which is 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. 4. For Moisture Sensitivity Level (MSL), please see product information page for ICL7106, ICL7107, ICL7107S. For more information on MSL, please see tech brief TB363. 5. Please refer to TB347 for details on reel specifications.
