DATASHEET 31/2 Digit, LCD/LED Display, A/D Converters
ICL7106, ICL7107, ICL7107S
The Intersil ICL7106 and ICL7107 are high performance, low power, 31/2 digit A/D converters. Included are seven 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. 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 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. Features Guaranteed zero reading for 0V input on all scales True polarity at zero for precise null detection 1pA typical input current True differential input and reference, direct display drive - LCD ICL7106, LED lCL7107 Low noise - less than 15µVP-P On-chip clock and reference Low power dissipation - typically less than 10mW No additional active circuits required Enhanced display stability Pb-free (RoHS compliant) Ordering Information

"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.
