ICL7136CPL+ - 3.5-Digit LCD A/D Converter | Analog Devices
MPN: ICL7136CPL+ ✓ AktifICL7136CPL+ Ringkasan
An integrated 3.5-digit A/D converter combines analog measurement, digital conversion, and display excitation in one package. This type of converter is used where a compact instrument must display a measured voltage, current, resistance, or temperature without requiring a separate display driver. The ICL7136CPL+ uses a dual-slope conversion technique, providing a measurement architecture suited to stable, low-rate instrumentation rather than high-speed signal acquisition.
The ICL7136CPL+ includes onboard segment drivers, segment decoders, a voltage reference, and a clock, reducing the number of external display-support components required. The Analog Devices product page identifies it as a production part and describes it as a low-power 3 1/2-digit A/D converter. The integrated display interface is intended for LCD displays, while the converter's differential-input capability supports measurement arrangements that reject common-mode effects when used with suitable input circuitry.
The dual-slope conversion method integrates the input over a fixed interval, providing a measurement result that is less sensitive to certain noise and timing variations than a simple instantaneous conversion. The device is intended for panel meters, digital instruments, laboratory measurement equipment, and other systems where a stable numeric display is required. External passive components and the selected input network remain important for achieving the intended accuracy and input impedance.
Typical uses include handheld meters, process-monitoring displays, temperature-measurement instruments, laboratory equipment, and embedded display panels. In each case, the ICL7136CPL+ can combine the measurement front end and LCD drive functions while leaving the host system free to focus on control, data logging, or user interaction.
Designers should follow the manufacturer pin-description table when assigning PCB nets and should confirm the display polarity, segment count, input configuration, reference arrangement, and bypass requirements against the manufacturer datasheet. The 40-pin PDIP footprint is mechanically straightforward but occupies substantial board area, so DIP availability and assembly method should be checked during product planning.
This product page consolidates the ICL7136 family specifications, verified package information, sourcing guidance, comparison parameters, and practical replacement considerations to support faster engineering evaluation and board-level planning.

Aplikasi Umum
ICL7136CPL+ cocok untuk 6 aplikasis: Digital Panel Meters, Temperature Measurement Instruments, Handheld Digital Meters, Process Monitoring Displays, Laboratory Measurement Instruments, Battery-Powered Sensor Readouts.
Digital Panel Meters
The ICL7136CPL+ fits standalone digital panel meters because it combines a 3.5-digit dual-slope converter with seven-segment decoders, display drivers, a reference, and a clock. The integrated LCD interface removes a separate display-driver subsystem and allows a compact instrument to show a measured voltage, current, or resistance. Designers should use the manufacturer pin-description and application diagrams to match segment polarity and the external input network, while the very high input impedance helps avoid loading of the measured source.

Temperature Measurement Instruments
The ICL7136CPL+ can form the measurement and display core of a temperature instrument when paired with an appropriate sensor interface. Its 3.5-digit resolution is well matched to panel-style temperature readouts, and differential or single-ended input operation allows the analog network to be arranged around the selected sensor. The reference, input components, and calibration method determine practical accuracy, so the manufacturer characteristic tables should be used before assigning temperature-error requirements.

Handheld Digital Meters
A handheld meter benefits from the ICL7136CPL+ because it integrates the conversion and LCD-drive functions into one 40-pin PDIP device. The result is a simpler low-rate instrument architecture that can display a measurement without a separate display controller. Low-power operation is central to this use case, but actual battery life depends on the selected operating mode, display characteristics, reference circuit, and external input network. Use the manufacturer data sheet to calculate current consumption and startup behavior.

Process Monitoring Displays
The ICL7136CPL+ is suitable for process-monitoring equipment that must present a locally readable numeric value from a slowly changing sensor signal. Its 3.5-digit dual-slope architecture, integrated LCD drivers, and high input impedance support a dedicated front panel without requiring a host processor for display formatting. For industrial equipment, validate supply tolerance, operating-temperature limits, grounding, and display performance in the final enclosure, and retain isolation or protection where the measured node requires it.

Laboratory Measurement Instruments
The ICL7136CPL+ can serve as the readout engine in a compact laboratory meter, bench instrument, or calibration display. Integrating the reference, clock, segment decoders, and display drivers reduces the number of assemblies while preserving a conventional 3.5-digit presentation. The measurement chain still needs careful passive selection and calibration, particularly when accuracy depends on resistor ratios and reference stability. Follow the manufacturer application circuit and input-common-mode requirements during schematic capture.

Battery-Powered Sensor Readouts
A battery-powered sensor readout can use the ICL7136CPL+ when the required measurement rate is low and a three-and-a-half-digit LCD is sufficient. The converter handles the measurement, decoding, and display drive in one package, which supports a compact and straightforward instrument design. Energy optimization depends on operating mode, duty cycling, display type, and external component selection, so confirm the manufacturer timing and supply-current specifications before setting the battery-life target.

Catatan Desain
Use the manufacturer pin-description table and application diagram as the authority for the 40-pin PDIP footprint. Keep the analog input and reference components close to their associated pins, route display outputs away from sensitive input nodes, and provide a clear ground path between the measurement and display sections. The through-hole package is mechanically simple, but its large footprint and 40 through-holes can dominate PCB density in compact instruments.
Do not treat every 40-pin 3.5-digit converter as interchangeable. Before fitting ICL7136CPL, ICL7136CPLZ, TC7136RCPL, or ICL7106RCPL, compare the actual pin names, display polarity, segment mapping, reference arrangement, input common-mode range, supply limits, and overrange recovery. The older ICL7106 may also require passive-value changes, so a PCB-level substitution must be confirmed against the relevant manufacturer documentation.
Preserve the intended measurement behavior by keeping high-impedance input routes short and guarding them from display-driver and clock nodes. Use the specified input and reference resistor network rather than substituting arbitrary values, because ratio errors can influence the displayed result. If the source has appreciable capacitance or leakage, evaluate settling time and input bias effects before relying on the converter's high input impedance.
Calculate the instrument's energy budget using the manufacturer's supply-current and operating-mode specifications. The ICL7136CPL+ integrates the converter and display support, but external components and the LCD still consume power. For battery operation, verify the duty cycle, conversion timing, display state, and reference-network losses rather than estimating only from the nominal device description.
