MAX14803CCM+ - 16-Channel High-Voltage Switch | Analog Devices
Артикул: MAX14803CCM+ ✓ АктивенMAX14803CCM+ Обзор
An analog switch is an integrated semiconductor device that routes analog signals between terminals under digital control. The MAX14803CCM+ belongs to the broader analog-switch hierarchy, where multiple SPST switches are controlled by a serial digital interface. Its 16-channel architecture reduces the number of control lines and PCB routing requirements compared with sixteen individually controlled discrete switches.
The MAX14803CCM+ uses HVCMOS process technology to provide high-voltage switching in a low-charge-injection design. Data is clocked into an internal 16-bit shift register and retained by a programmable latch with enable and clear inputs. This architecture supports grouped switch-state management, making the device suitable for systems that need precise control over multiple high-voltage signal paths.
Low charge injection helps limit unwanted voltage transients when a switch changes state. With a specified on-resistance of 48 ohm and switching times of 3500 ns for both turn-on and turn-off, the device favors controlled, repeatable switching over minimum propagation delay. The 50 dB isolation rating further supports applications requiring separation between controlled high-voltage paths.
Typical uses include ultrasonic-imaging systems, printer electronics, and other industrial equipment that requires numerous high-voltage switching channels. The MAX14803 family is specifically identified for ultrasonic imaging and printer applications, while its serial shift-register control makes it appropriate for systems that can serialize switch commands from a controller or programmable logic device.
PCB design should preserve the manufacturer's recommended supply decoupling and high-voltage clearances. Although the logic supply spans only 2.7 V to 5.5 V, the switched channels are intended for high-voltage signals, so creepage, clearance, insulation, and connector requirements must be evaluated for the actual operating voltage. The 48-pin TQFP package also requires thermal and assembly consideration at elevated ambient temperatures.

Типичное применение
MAX14803CCM+ подходит для 6 применениеs: Ultrasonic Imaging Systems, Printer and Imaging Equipment, High-Voltage Signal Routing, Industrial Control and Automation, Precision Test and Measurement, Medical Diagnostic Equipment.
Ultrasonic Imaging Systems
The MAX14803CCM+ fits ultrasonic-imaging systems that require numerous controlled high-voltage signal paths in a single IC. Its 16 independent SPST switches replace a large number of discrete routing elements, while the internal 16-bit shift register simplifies serialized control from a controller or programmable logic device. The verified 48 ohm on-resistance and 3500 ns turn-on and turn-off times must be included in the receiver and transmitter signal-chain analysis. Because the supplied data does not state the maximum switched voltage or absolute charge injection, the system integrator must confirm both from the manufacturer datasheet before defining transducer drive amplitude and protection limits.
Рекомендуется
Printer and Imaging Equipment
The MAX14803CCM+ is suitable for printer and imaging equipment that requires a dense bank of controlled analog switches. Its 16-channel SPST organization consolidates routing functions without requiring sixteen separate control inputs, and the programmable latch with enable and clear inputs supports coordinated switching sequences. The 2.7 V to 5.5 V supply range allows operation from common low-voltage digital logic rails. Engineering validation should compare the specified 3500 ns switching interval with the required image or print timing, while accounting for the 48 ohm on-resistance and the maximum voltage that each switched node can tolerate.
Рекомендуется
High-Voltage Signal Routing
The MAX14803CCM+ can be used where multiple high-voltage signal paths must be routed under digital supervision. Its 16 SPST channels provide a compact switching matrix, and the 50 dB isolation specification helps maintain separation between controlled paths. The device uses HVCMOS process technology and a serial shift-register architecture, allowing switch commands to be loaded systematically rather than through a dedicated pin for every channel. Designers should treat the verified 48 ohm on-resistance as the primary attenuation factor and verify maximum switched voltage, off-state behavior, isolation conditions, and any required external protection because those details were not included in the supplied search data.
Рекомендуется
Industrial Control and Automation
For industrial control equipment, the MAX14803CCM+ offers a practical way to route multiple analog or high-voltage nodes with a compact serialized interface. Its 48-pin TQFP package supports conventional surface-mount assembly, and the -40 °C to +85 °C operating range covers many factory environments. The internal 16-bit register and latch-based state retention can simplify repeatable multi-channel state management. Nevertheless, industrial qualification requires checking the maximum node voltage, isolation test conditions, switching transients, and controller logic levels. The 48 ohm on-resistance and 3500 ns switching times also need to be compared with actuator or sensor timing requirements.
Рекомендуется
Precision Test and Measurement
The MAX14803CCM+ can support test-and-measurement systems requiring several repeatable switch paths for stimuli, returns, or fixture isolation. Its low-charge-injection architecture is valuable when transitions must not create excessive unintended voltage pulses, while the specified 48 ohm on-resistance provides a defined basis for insertion-loss analysis. Both turn-on and turn-off times are 3500 ns, making the device appropriate for systems that can accommodate controlled switching rather than extremely fast edge timing. Before selecting it, verify the exact charge-injection figure, off resistance, maximum voltage, and isolation conditions from the manufacturer datasheet, since these values were not present in the supplied sources.
Рекомендуется
Medical Diagnostic Equipment
The MAX14803CCM+ may be used in diagnostic and medical instrumentation when a design requires multiple controlled high-voltage paths, subject to the manufacturer's stated safety and application limits. Its 16 SPST channels and serialized 16-bit shift register reduce routing-component count and can simplify controller integration. The -40 °C to +85 °C temperature range provides useful environmental coverage, but medical-system suitability cannot be established from the temperature rating alone. Engineers must verify maximum switched voltage, isolation parameters, leakage behavior, charge injection, applicable medical standards, and the complete pin arrangement. Any candidate replacement must also preserve those validated electrical and mechanical characteristics.

Заметки по проектированию
The verified 2.7 V to 5.5 V specification applies to the device supply, but it does not establish the maximum voltage that may appear on a switched node. Before power-up, separate the logic rail from the high-voltage signal domain and verify absolute maximum ratings in the manufacturer datasheet. Place the required supply-decoupling capacitors close to the supply and ground pins using the datasheet's layout recommendations; suitable capacitor voltage ratings and dielectric types depend on the final rail conditions.
Treat the 48-pin TQFP as a mixed-signal and potentially high-voltage-routing component. Keep switched-node copper away from low-level control and ground paths where isolation is required, and preserve package creepage and clearance distances based on the actual maximum working voltage. Do not infer isolation solely from the 50 dB figure: verify its test frequency, test conditions, and channel configuration in the official datasheet before defining the PCB keepout area.
The published 48 ohm on-resistance and 3500 ns turn-on and turn-off times are the primary verified figures for signal-chain evaluation. Do not assume that a family member or alternate ordering code retains identical limits without checking its timing table. Likewise, the supplied search results do not provide maximum switched voltage, off resistance, leakage, or absolute charge injection; any design using those parameters requires a datasheet-based value rather than an inferred specification.
Account for switch resistance and transition timing when calculating attenuation and settling behavior in ultrasonic-imaging, printer, and test-equipment signal paths. The serial shift register allows grouped state loading, but the system must preserve the required clock, enable, and clear sequencing from the manufacturer timing diagrams. Validate crosstalk, injected transients, and charge injection on the final high-impedance nodes because the supplied verified data does not quantify those values.
