ICL7117CMH 3½-Digit ADC | Maxim Integrated | 44-Terminal QFP
MPN: ICL7117CMH ✗ जीवन की समाप्तिICL7117CMH अवलोकन
An ADC is an analog-to-digital converter, a semiconductor that converts an analog input voltage into a digital representation. The ICL7117CMH belongs to the broader data-conversion and signal-processing hierarchy, where precision measurement systems commonly combine an analog input, a conversion engine, digital control or processing, and a display or communications interface. The display-hold function is intended to preserve a measured value so it can be viewed or transferred before the next conversion sequence changes the displayed result.
The package information is the most concrete differentiator for PCB design. A 44-terminal gull-wing QFP provides external connections for power, analog input, digital output, reference, control, and display-related functions, subject to the exact pin assignment in the manufacturer datasheet. Its 0.8 mm terminal pitch allows a compact square surface-mount footprint, while the 10.0075 mm package dimensions require PCB land patterns and courtyard planning based on the manufacturer drawing. The QFP format also provides mechanical lead support and is generally more convenient for automated board assembly than a fine-pitch leadless package.
ICL7117CMH is appropriate for panel meters, laboratory instruments, industrial monitoring equipment, digital weighing systems, process measurement, and other applications requiring a dedicated display-oriented ADC. In these systems, the converter accepts a conditioned analog signal, performs conversion, and presents a stable numerical result. The external circuitry normally defines the input range, reference voltage, integration timing, and display interface behavior.
Designers should follow the Maxim ICL7117CMH datasheet for pinout, electrical limits, recommended input and reference networks, timing, and decoupling. Because the verified information does not state the complete electrical ratings, verify the converter resolution, input voltage range, reference arrangement, operating temperature range, supply requirements, and timing values against the manufacturer document before releasing a PCB or production design.
This product page combines the verified package and product identity information with practical integration guidance, application mapping, and comparison context. It is intended to help engineers locate the correct ICL7117CMH documentation, understand the package implications, and plan a PCB or replacement review without treating general ADC characteristics as guaranteed ICL7117CMH specifications.

सामान्य अनुप्रयोग
ICL7117CMH के लिए उपयुक्त है 6 अनुप्रयोगs: Digital Panel Meters, Laboratory Measurement Instruments, Industrial Process Monitoring, Temperature Measurement Displays, Digital Weighing Systems, Data Acquisition and Test Equipment.
Digital Panel Meters
The ICL7117CMH fits compact digital panel meters because its three-and-a-half-digit conversion format is designed around a readable numerical display, and the display-hold function can preserve a selected reading for an operator. The 44-terminal QFP provides dedicated external connections for the analog section, reference, digital section, timing, and display-related signals. Designers should follow the Maxim Integrated datasheet for the exact pin assignment and recommended support network.
अनुशंसित
Laboratory Measurement Instruments
ICL7117CMH is suitable for laboratory instruments that present a stable three-and-a-half-digit measurement while a technician adjusts a sensor or test condition. Display hold helps retain the value used as a reference, while the QFP package keeps the converter compact in bench instruments. Signal conditioning, input protection, reference design, calibration, and display decoding should be completed according to the manufacturer application information.
अनुशंसित
Industrial Process Monitoring
The ICL7117CMH can support industrial process monitoring when the target quantity is reduced to a readable decimal value for local display. Its display hold supports temporary retention during inspection, while the 44-terminal package exposes the converter's separate functional sections. The transmitter front end still needs sensor excitation, filtering, surge protection, isolation, and calibration appropriate to the measured process variable.
अनुशंसित
Temperature Measurement Displays
ICL7117CMH is applicable to temperature measurement displays that use a linearized or compensated sensor signal and present a three-and-a-half-digit result. The converter's display-oriented architecture simplifies a standalone instrument, while hold allows the operator to retain a value while comparing it with a reference. Sensor type, excitation, linearization, reference stability, and calibration determine whether the converter's timing and accuracy suit the final system.
अनुशंसित
Digital Weighing Systems
The ICL7117CMH fits digital weighing systems that prioritize a stable numeric display over high-speed waveform acquisition. A load-cell signal is conditioned into the converter's input range, and the display-hold function lets an operator retain a value during inspection. Mechanical stability, excitation symmetry, input filtering, calibration coefficients, overload protection, and regulatory requirements remain outside the ADC's basic conversion function.
अनुशंसित
Data Acquisition and Test Equipment
ICL7117CMH is useful in data-acquisition and test equipment that combines an analog measurement with a local numeric readout. The three-and-a-half-digit result is appropriate for meter-style systems, and display hold assists comparison or setup. Its 0.8 mm-pitch 44-terminal QFP requires careful land-pattern implementation, while reference and timing networks should follow the manufacturer's recommended application circuit for stable readings.

डिज़ाइन नोट्स
Design the PCB land pattern from the Maxim Integrated package drawing rather than from the distributor terminal count alone. The verified package is a square, 44-terminal gull-wing QFP with 0.8 mm pitch and 10.0075 mm width and length. Confirm pin numbering, lead-tip tolerances, courtyard limits, paste volume, and the footprint's orientation before fabrication; a dimensionally similar but non-approved footprint can create solder or bridging defects.
Do not treat the ICL7117CMH+, ICL7117CMH, and other partially specified listings as automatically interchangeable. The plus suffix may represent a distinct ordering or qualification option, so the BOM must identify the complete manufacturer part number. Before substitution, compare the ordering table, temperature grade, package code, lifecycle status, and electrical limits against the original production specification.
Route the analog input and reference-related nets away from digital timing and display outputs, and place the manufacturer's recommended input, reference, bypass, and timing components close to their associated pins. Because the verified information does not state the complete pin map or recommended network values, use the Maxim Integrated datasheet for exact connections. This separation reduces switching coupling and helps preserve the stability of the displayed measurement.
अनुपालन जानकारी
Compliance attributes are not stated in the verified product information. AEC-Q100 is not applicable because this product is an analog-to-digital converter rather than an automotive-qualified power semiconductor; verify any automotive qualification separately from the manufacturer ordering information.
