31/2 Digit, LCD/LED Display, A/D Converters

DATASHEET

The Intersil ICL7106 and ICL7107 are high performance, low

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

• On-chip clock and reference

• Low power dissipation - typically less than 10mW

• No additional active circuits required

• Enhanced display stability

• Pb-free (RoHS compliant)

NOTES:

1. “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.
