ICL7106EPL+ - 3.5-Digit LCD ADC | Maxim Integrated
Teilenummer: ICL7106EPL+ ✗ AbgekündigtICL7106EPL+ Übersicht
An analog-to-digital converter, or ADC, converts a continuously varying analog voltage into a numeric value. A 3.5-digit integrating ADC such as the ICL7106 uses an integrating measurement approach and includes display decoding and drive circuitry, reducing the external component count required for a standalone panel meter. The ICL7106 differs from the related ICL7107 by driving a nonmultiplexed LCD, while the ICL7107 is intended for LED-display applications. This distinction makes display type an essential PCB and firmware-independent hardware selection criterion.
The principal system-level benefits are integration and measurement simplicity. A high-input-impedance measurement front end allows the converter to work with sensor and instrumentation circuits without adding a separate display driver. On-board segment decoders, polarity and digit drivers, a voltage reference, and a clock eliminate several discrete functions from the meter design. These characteristics are especially useful in standalone laboratory instruments, temperature controllers, weighing indicators, process monitors, and service equipment where the analog input must appear directly as a readable numerical measurement.
Because the ICL7106 is intended for low-power measurement rather than high-speed waveform acquisition, system timing and input conditioning determine practical performance. The input network, reference arrangement, integration period, clock source, and bypass components should follow the manufacturer's application guidance. Decoupling must be placed close to the supply and reference pins, while the analog input path should avoid long traces and sources of leakage. The LCD interface and converter functions are integrated, but the display still requires the appropriate glass connections and suitable common and segment drive arrangement.
Typical applications include digital panel meters, temperature measurement instruments, laboratory readouts, industrial process indicators, portable measurement equipment, and equipment with an integrated numeric display. In these systems, the ICL7106EPL+ serves as both the measurement engine and the LCD interface. Designers should confirm the input range, reference voltage, conversion timing, display configuration, and supply requirements against the manufacturer datasheet before finalizing the analog front end and printed-circuit-board layout.
For PCB design, begin by assigning the 40-pin PDIP footprint and checking the manufacturer's pin-description table for analog inputs, reference connections, supply rails, ground pins, clock connections, and LCD outputs. Avoid routing LCD segment and digit lines next to high-impedance analog inputs. Place input and bypass capacitors close to their associated pins, provide a stable ground return, and keep the analog and display paths physically separated where the board area permits.
This product page combines the manufacturer's family-level technical description, package and ordering information, related 40-pin device data, application engineering guidance, and a replacement-focused comparison. It is intended to help engineers determine whether the ICL7106EPL+ matches the required display technology, package, lifecycle requirement, and instrumentation architecture before committing the design to production.

Typische Anwendungen
ICL7106EPL+ ist geeignet für 6 Anwendungs: Digital Temperature Panel Meter, Laboratory Digital Readout, Industrial Process Indicator, Portable Measurement Instrument, Weighing Scale Display, Service and Calibration Instrument.
Digital Temperature Panel Meter
The ICL7106EPL+ suits a compact temperature instrument in which a sensor signal is converted into a direct 3.5-digit LCD reading. Its integrated segment decoder, polarity and digit drivers, voltage reference, and clock reduce the number of separate display-support components required around the converter. The 40-pin PDIP package is also convenient for a hand-assembled or through-hole industrial instrument. The analog front end must provide the sensor-specific range, filtering, and source impedance, while the LCD glass and PCB routing must follow the manufacturer's pin and drive arrangement.
Empfohlen
Laboratory Digital Readout
The ICL7106EPL+ can form the measurement and display core of a laboratory readout that prioritizes a stable numerical presentation over rapid waveform acquisition. Integrating the conversion function with a nonmultiplexed LCD driver reduces the component count needed for a dedicated panel-meter instrument. A 3.5-digit display provides the characteristic one-digit overrange indication useful for basic measurement displays. Design effort should focus on low-leakage analog routing, an appropriate input network, stable reference behavior, and short paths between the converter, bypass components, and display.
Empfohlen
Industrial Process Indicator
For an industrial process indicator, the ICL7106EPL+ provides a straightforward path from a conditioned analog measurement to a readable LCD. The integrated clock, reference, segment decoding, and display drive functions are valuable where panel space and reliability favor a compact through-hole implementation. The device should be selected only after confirming that the measurement bandwidth, accuracy target, input range, and environmental requirements fall within the ICL7106 family's operating limits. Add input protection and filtering appropriate to the sensed process rather than relying on the converter for transient protection.
Empfohlen
Portable Measurement Instrument
The ICL7106EPL+ is useful in portable instruments that display a slow-moving measurement directly to the operator. Because the converter and nonmultiplexed LCD driver are integrated, a battery-powered meter can minimize the number of display-driver components and reduce board complexity. Power budgeting must account for the device, LCD, reference, input network, and any backlight or indicator circuitry; a numeric power figure for the ICL7106EPL+ should be taken from the manufacturer data sheet. Mechanical design should also account for the 40-pin PDIP footprint and its through-hole assembly requirements.
Empfohlen
Weighing Scale Display
A scale or load-cell signal can be conditioned and measured by the ICL7106EPL+ for direct 3.5-digit LCD display. The integrated display functions allow the converter to serve as the central measurement component rather than merely feeding a separate controller. Mechanical excitation, bridge excitation stability, input filtering, and common-mode range determine whether the measurement architecture is suitable; these values must be verified against the manufacturer specifications. The PCB should keep the sensitive bridge and analog section away from switching supplies and LCD drive traces to reduce coupling into the measurement result.
Empfohlen
Service and Calibration Instrument
The ICL7106EPL+ is appropriate for service instruments that need a stable, direct numeric display for slowly changing electrical or sensor measurements. Its nonmultiplexed LCD interface avoids the need for a separate display-driver IC, while the 40-pin PDIP package supports conventional through-hole prototyping and serviceable assemblies. A robust instrument still needs careful reference decoupling, input conditioning, calibration provisions, and separation from noisy power stages. Review the manufacturer's recommended circuit and pin descriptions because the precise input and reference components depend on the selected measurement range and desired resolution.

Wichtigste Unterscheidungsmerkmale
- Direct nonmultiplexed LCD drive (vs. ICL7107RCPL-4)
- Integrated meter-support functions (vs. General-purpose external-display ADC)
- Same 40-pin PDIP footprint for family-level substitution (vs. ICL7106CPL)
Designhinweise
Keep the high-impedance analog input path short and isolated from LCD segment and digit outputs. Place input-filtering and bypass capacitors close to their associated ICL7106EPL+ pins, use a low-impedance ground return, and avoid routing sensitive input traces beneath switching or display-driver areas. A through-hole prototype can still suffer leakage and coupling problems if long exposed analog nets collect contamination, so clean the board and guard sensitive nodes where the manufacturer guidance permits.
Do not treat ICL7106 and ICL7107 ordering codes as display-equivalent. The manufacturer describes ICL7106 as the nonmultiplexed LCD version and ICL7107 as the LED-display version, even though related family members can use the same 40-pin PDIP outline. Verify every LCD output connection against the selected converter and display glass. For a replacement, also compare the temperature-grade and lead-free suffix rather than assuming that matching the PCB footprint is sufficient.
Implement the supply, reference, clock, and bypass network using the manufacturer application circuit rather than a generic display-module layout. Keep reference and bypass connections physically short, and place bulk and high-frequency decoupling at the device pins where appropriate. Because no exact quantity-break price or numeric supply specification was extracted for the exact EPL+ ordering code, request an order-specific quote and verify electrical limits from the exact manufacturer data sheet before release.
The 40-pin PDIP format permits through-hole assembly and offers a larger exposed thermal path than many small-outline packages, but actual temperature rise still depends on supply voltage, dissipation, airflow, board construction, and ambient temperature. No numerical power-dissipation or junction-temperature figure was extracted for the exact device, so do not substitute values from another ICL7106 ordering code. Use the exact data-sheet electrical limits and the calculated operating dissipation for any thermal qualification.
Compliance-Informationen
The + suffix indicates the lead-free product designation. No explicit RoHS, REACH, halogen-free, conflict-minerals, or automotive-qualification statement was extracted for the exact ordering code. AEC-Q100 is treated as not applicable because the device is an industrial measurement ADC rather than an automotive-qualified component.
