ICL7106IP 概要
An A/D converter is an analog-to-digital converter that transforms a continuously varying voltage or current-derived signal into a numeric representation. The ICL7106 belongs to the display-oriented A/D converter hierarchy, combining measurement conversion, display decoding, display drive, reference voltage, and timing functions in one device. Its integrated LCD backplane drive is intended to reduce the external circuitry required for panel instruments.
Key features of the ICL7106 include 3.5-digit resolution, seven-segment display decoding, LCD display-driver capability, an integrated reference, an integrated clock, true differential input and reference support, and dual-slope conversion. The device family is designed to reject interference signals common in industrial environments, while ratiometric measurement support is useful for ohms and bridge-transducer applications.
The ICL7106 uses dual-slope conversion rather than a high-speed successive-approximation architecture. This approach integrates an input over a fixed measurement interval and compares the resulting charge with a reference-derived ramp. The architecture is well suited to panel meters, digital scales, temperature indicators, and other systems where measurement rate is less important than stable displayed readings and straightforward system integration.
Typical applications include digital panel meters, resistance measurement instruments, bridge-sensor instrumentation, industrial process displays, laboratory meters, weighing systems, and portable measurement equipment. The LCD-focused ICL7106 is generally preferable to LED-display converter variants when the design uses a multiplexed liquid-crystal panel.
Designers should follow the manufacturer datasheet for the exact pin assignments, reference connections, clock requirements, display timing, and input common-mode limits. The 40-pin PDIP footprint also requires sufficient board space, careful decoupling, and routing that separates sensitive analog input and reference paths from display-drive and digital timing nodes.
This page consolidates manufacturer information, distributor availability, pricing context, package identification, and design guidance for engineers evaluating the ICL7106IP in new or replacement LCD instrument designs.

Digital Panel Meter
The ICL7106IP fits digital panel meters that require a stable 3.5-digit numeric readout from an analog sensor signal. Its integrated seven-segment decoder, LCD driver, reference, and clock reduce the number of separate display-support components. The dual-slope conversion method is useful when the meter prioritizes repeatable displayed readings over high sampling rate. In a typical instrument, the sensor signal enters the differential input, while the reference and input filtering networks are arranged according to the manufacturer datasheet. LCD segment and backplane wiring must match the selected panel and verified pinout.
おすすめ
Resistance Measurement Instrument
ICL7106IP can support resistance-measurement instruments when the measurement is arranged with suitable excitation and ratiometric signal conditioning. The device provides true differential input and reference capability, which is useful when the measured resistance is referenced to a controlled supply or bridge arrangement. The external resistor network, input protection, reference accuracy, and calibration method determine the final resistance range and error. Because the verified data does not specify exact input limits or conversion timing, the circuit must be checked against the current manufacturer datasheet before component selection is finalized.
おすすめ
Bridge Transducer Readout
The ICL7106IP is appropriate for a simple bridge-sensor readout when the transducer output is converted into a differential analog signal and the display range is designed around the bridge excitation. The true differential input and reference functions support ratiometric measurement, allowing the converter to compare the bridge signal against its own reference rather than depending on an unrelated absolute source. Practical designs still require excitation regulation, input filtering, common-mode verification, and calibration. The supplied data identifies bridge and ratiometric measurement use cases but does not provide a specific bridge range or accuracy table.
おすすめ
Industrial Process Display
ICL7106IP can be used as the measurement and display core in a compact industrial process indicator. Its LCD-focused architecture, integrated clock, and dual-slope conversion suit slower measurements where display readability and periodic-interference rejection are more important than high-speed sampling. The analog front end should include protection appropriate to the process signal, while the reference and input traces should be kept away from display and clock nodes. Final qualification requires verified operating voltage, temperature, noise, and environmental specifications from the manufacturer datasheet.
おすすめ
Temperature Indicator
ICL7106IP can present a temperature-derived voltage on a 3.5-digit LCD panel when a suitable sensor front end and linearization network are used. The converter's integrated reference and display functions simplify a dedicated temperature-display instrument, while dual-slope conversion is compatible with slow thermal measurements. The sensor's excitation, transfer curve, cold-junction compensation if applicable, and display scaling determine the achievable range and resolution. Use the manufacturer input and reference guidance to set the analog network and verify calibration across the intended temperature span.
おすすめ
Portable Measurement Equipment
ICL7106IP is suitable for portable, battery-powered measurement equipment where a low-power LCD readout is preferred over an LED display. The integrated clock, reference, decoder, and LCD drivers can reduce board area in a handheld meter, while the 3.5-digit format matches common panel-meter ranges. Battery operation still requires careful review of supply voltage, quiescent consumption, input protection, and display contrast. The verified data does not provide current consumption or operating-voltage values, so those parameters must be taken from the current manufacturer datasheet before final battery sizing.

設計ノート
Route the true differential input, reference, and analog ground paths as a compact signal chain. Keep these nets away from LCD segment outputs, clock nodes, and switching or high-current supply paths. Use the manufacturer reference layout and component placement as the starting point; the verified data does not provide a complete PCB layout, so exact trace widths and grounding topology require the current datasheet and application guidance.
Do not substitute an LED-display ICL7107 for an ICL7106 LCD design without auditing every display connection. The verified family information distinguishes the LCD version from the LED version, and the display drivers have different external load requirements. Also confirm that the 40-pin PDIP footprint, LCD backplane arrangement, reference wiring, and clock components match the selected board before approving a replacement.
Design the supply and decoupling network around the exact manufacturer operating-voltage and current limits, which are not included in the verified data. Place required bypass capacitors close to the supply pins and preserve the datasheet's recommended component values. Because the ICL7106 includes analog conversion, reference, clock, and display-drive functions, inadequate bypassing can affect measurement stability and display behavior.
For ratiometric resistance or bridge measurements, keep the reference and input networks matched and terminate them consistently. Input filtering should reject switching and display-related interference without degrading the intended measurement bandwidth. Validate common-mode limits, source impedance, and conversion timing with the actual sensor and display; these values must be obtained from the manufacturer datasheet rather than estimated.
コンプライアンス情報
Compliance information was not explicitly provided in the verified web data. AEC-Q100 is treated as not applicable because no automotive qualification is stated for ICL7106IP; this should not be interpreted as an automotive certification.
