ICL7116CJL - 3.5-Digit LCD Display ADC | Maxim Integrated
MPN: ICL7116CJL ✗ Cuối đờiICL7116CJL Tóm tắt
A dual-slope analog-to-digit converter is a sigma-delta-style measurement architecture that integrates an unknown input voltage over a fixed interval and then measures the time required for a reference ramp to balance the result. In the ICL7116, this measurement method supports a stable digit-oriented output intended for panel meters, laboratory instruments, counters, and other display-oriented measurement equipment.
The ICL7116CJL combines a 3.5-digit A/D conversion function with a display driver and display hold capability. Integrating these functions reduces the number of separate devices required in a digital instrument. The converter output can be used with the associated segment-driver circuitry to present a measured value directly on an LCD panel, making the device especially relevant to compact, panel-mounted meter designs.
This IC belongs to the ADC/DAC category within integrated circuits and implements the broader hierarchy of data-acquisition IC, display interface, and display-driver functions. Its dual-slope architecture, 3.5-digit measurement format, and dedicated display-driver outputs distinguish it from general-purpose flash, SAR, and high-resolution pipeline ADC families. The 40-pin CDIP construction also favors leaded industrial and laboratory assemblies rather than compact surface-mount production.
Typical uses include digital panel meters, handheld test instruments, counters, laboratory measurement equipment, process-monitoring displays, and educational measurement products. The integrated display function is particularly useful when a numeric result must be read directly rather than converted to another bus format or processed by a separate display controller.
When laying out a new board, preserve the pin arrangement and bypass requirements of the ICL7116 family reference circuit rather than treating the LCD outputs as ordinary general-purpose logic. Confirm LCD segment characteristics, reference-source stability, input range, and timing against the manufacturer datasheet before releasing production artwork, especially where the ceramic package is exposed to temperature extremes or mechanical vibration.
This product page consolidates the confirmed ICL7116CJL identity, package information, lifecycle considerations, technical alternatives, application guidance, and design notes into one engineering reference. It also distinguishes verified drop-in options from alternatives that require pinout, electrical, or package validation before substitution.

Ứng dụng tiêu biểu
ICL7116CJL phù hợp cho 6 Áp dụngs: Digital Panel Meters, Laboratory Test Instruments, Industrial Process Monitoring, Handheld Measurement Devices, Educational Measurement Instruments, Legacy Instrumentation Repair.
Digital Panel Meters
The ICL7116CJL is well suited to digital panel meters because its 3.5-digit dual-slope converter and integrated LCD driver can present a measured value without a separate display-controller IC. The device is installed in a 40-pin through-hole ceramic DIP and connected to the meter input, reference network, and LCD. This integration reduces external circuitry, while the 3.5-digit format provides sufficient resolution for pressure, temperature, level, and general process-monitoring displays. Before layout release, verify the input range, reference accuracy, segment mapping, and bypass arrangement against the manufacturer datasheet.
Được đề xuất
Laboratory Test Instruments
The ICL7116CJL provides a direct measurement-and-display path for laboratory instruments that measure an analog quantity and show the result locally. Its dual-slope conversion method is suited to stable, digit-oriented readings, while the integrated display driver reduces the need for separate segment-driver circuitry. The 40-CDIP package is appropriate for a leaded instrument platform assembled for serviceability rather than minimum board area. Confirm reference stability, input settling, conversion timing, and calibration behavior in the manufacturer application circuit before production.
Được đề xuất
Industrial Process Monitoring
The ICL7116CJL can serve as the front-panel measurement engine in industrial process-monitoring equipment when the measured variable can be represented by a three-and-a-half-digit LCD result. Combining conversion and display control simplifies a rugged panel-meter design and leaves fewer interconnects between the analog input and the human-readable display. The ceramic DIP construction supports through-hole maintenance and repair workflows. Design the input network and reference section for the required measurement range, and verify LCD drive compatibility, operating temperature, and long-term calibration requirements.
Được đề xuất
Handheld Measurement Devices
The ICL7116CJL fits handheld and portable measurement devices that prioritize a readable numerical display over a high-speed data interface. The 3.5-digit dual-slope converter produces a conventional meter-style result, and the integrated LCD driver reduces the component count of the display subsystem. Its 40-pin through-hole package suits serviceable leaded designs and is less appropriate for highly compact surface-mount products. Validate battery-derived supply behavior, display readability, measurement settling, and reference-current demand in the target enclosure.
Được đề xuất
Educational Measurement Instruments
The ICL7116CJL is applicable to educational meters, bench instruments, and teaching systems where a direct three-and-a-half-digit LCD display is central to the user experience. Its integrated converter and display-driver functions simplify construction around the ICL7116 family reference design, while the through-hole ceramic package remains easy to probe and service. Engineering teams should verify input protection, calibration access, LCD segment assignment, and supply grounding before building a training platform, especially when students will access test points and adjustment components.
Được đề xuất
Legacy Instrumentation Repair
The ICL7116CJL is relevant to repair and continuation of legacy panel instruments that specifically use the 40-pin ceramic-DIP configuration and require the original display-driver architecture. Installing the device allows an existing analog front end, reference network, and LCD segment wiring to remain intact rather than replacing the measurement subsystem with a different ADC family. Confirm pin numbering, connector orientation, and component tolerances before installation.

Ghi chú thiết kế
Use the 40-pin ceramic DIP footprint and assign every LCD segment and control connection from the manufacturer pin-description table. Place the reference and input-network components close enough to preserve the settling behavior assumed by the dual-slope conversion circuit. A through-hole package offers generous routing space, but the LCD traces should still remain away from high-current switching nodes to minimize coupled display noise.
Follow the manufacturer reference circuit for supply bypass and reference-decoupling components. Reference stability directly affects the displayed measurement, so avoid long shared paths and provide local return routing for the analog and display sections. Check supply voltage limits, quiescent demand, and reference-source current against the electrical characteristics before connecting the device to a battery-derived or regulated laboratory supply.
Do not substitute an ordinary ADC merely because it has a similar conversion speed. The defining value of the ICL7116CJL is the combination of dual-slope conversion, 3.5-digit presentation, integrated LCD drive, and display hold. Also verify ceramic versus plastic package material, lead pitch, row spacing, and pin numbering before ordering a replacement for an existing instrument.
