MAX14800CCM+ - 16-Channel High-Voltage Analog Switch | Maxim
N.º de pieza: MAX14800CCM+ ✗ Fin de vidaMAX14800CCM+ Descripción general
An analog switch is an integrated semiconductor that routes signals between an input and an output under digital control. The MAX14800CCM+ belongs to the broader analog-switch hierarchy, which includes multiplexing functions, signal-routing ICs, and interface ICs. Its 16 independent channels consolidate parallel high-voltage switching into one package, reducing component count and simplifying board-level control when a system must scan multiple transducers, printer heads, or other high-voltage sensing elements.
The primary feature set includes 16 SPST channels, low charge injection, 48 ohm on resistance, high-voltage operation, and a serial digital control interface. Low charge injection helps limit unwanted voltage transients when a switch changes state, which is especially important when the connected system handles small-signal measurements. The 48-LQFP package provides a standardized surface-mount footprint and exposed thermal spreading capability, although exact thermal limits, maximum signal voltage, supply voltage, and timing values must be confirmed in the manufacturer datasheet.
Internally, the MAX14800CCM+ uses high-voltage CMOS technology to implement the switching array and control logic. The serial interface allows a host controller to load switching states into the device, reducing the number of discrete control lines needed for 16 channels. Because timing and propagation delay affect scan synchronization, system designers should use the manufacturer timing diagrams when calculating settling windows for successive transducer or printer-channel activations.
Typical uses include ultrasonic diagnostic imaging, industrial ultrasonic inspection, medical ultrasound acquisition systems, high-voltage inkjet and piezoelectric printers, and other multichannel high-voltage switching assemblies. In these applications, the device can sequentially connect multiple sensing or drive lines to shared downstream circuitry while the digital interface coordinates channel selection.
The primary design consideration is ensuring that external signal amplitude, supply levels, timing, and pin termination satisfy every operating condition stated in the manufacturer datasheet. PCB layout should preserve a common return path, place decoupling components close to the appropriate supply pins, and keep sensitive analog routing away from digital control and switching-current paths.
This page combines verified product identity, package information, family-level alternatives, pricing placeholders, and application-specific engineering guidance. It distinguishes documented characteristics from parameters that still require direct confirmation from the manufacturer datasheet, helping engineers evaluate the MAX14800CCM+ without treating unverified figures as design limits.

Industrial Ultrasonic Inspection
The MAX14800CCM+ is suitable for industrial ultrasonic inspection equipment that scans multiple probes or measurement paths. Its 16-channel SPST architecture consolidates channel selection, and the documented 48 ohm on-resistance provides a defined path resistance for signal routing. Low charge injection is useful when the acquisition chain must preserve small signals around switching events. According to the manufacturer datasheet, high-voltage CMOS technology supports the switching function, but cable-length, ringing, and parasitic-capacitance effects must be evaluated during sensor-interface design.

Piezoelectric Inkjet Printer
The MAX14800CCM+ fits multichannel piezoelectric printer electronics requiring controlled selection of high-voltage drive or sensing paths. Its 16 SPST channels provide a compact switching array, while the digital interface simplifies coordinated firing sequences. According to the manufacturer datasheet, printers are an explicit target application alongside ultrasonic imaging. Designers should compare the exact MAX14800 voltage and timing limits with the actuator waveform, account for switching transients at the load, and use local energy-storage and protection networks where required.

Medical Ultrasound Acquisition
The MAX14800CCM+ can support medical ultrasound acquisition front ends that require multiple high-voltage signal paths and controlled switching. Low charge injection helps minimize disturbance at the input of sensitive downstream stages, while 16 channels allow probe or receiver selection to be consolidated. According to the manufacturer datasheet, the device is intended for ultrasonic imaging applications. Medical use still requires system-level validation of isolation, leakage, applied-part requirements, fault behavior, and the exact electrical limits documented for the selected variant.

High-Voltage Test and Measurement
The MAX14800CCM+ is applicable to multichannel test systems that route high-voltage nodes under digital control. Its 16 SPST channels provide parallel path selection, and the documented 48 ohm on-resistance supports predictable impedance matching to downstream instrumentation. Low charge injection can reduce command-induced artifacts when low-level measurements follow a switching event. According to the manufacturer datasheet, exact maximum voltage and bandwidth must be respected; test-fixture isolation, leakage paths, discharge provisions, and safe discharge timing must be independently engineered.

Piezoelectric Sensor Multiplexing
The MAX14800CCM+ can multiplex several piezoelectric sensors into a shared measurement chain when low injected charge and controlled switching are important. The 16 SPST channels reduce wiring complexity, and the digital serial interface simplifies state management compared with individually controlled discrete switches. According to the manufacturer datasheet, the device supports high-voltage switching for ultrasonic and printer applications. Designers must account for sensor capacitance, cable ringing, leakage through the printed circuit board, and settling time between adjacent channel measurements.

Notas de diseño
Route each high-voltage switch path with care for clearance, leakage, and parasitic coupling. The verified material confirms a 48-LQFP package and high-voltage switching but does not specify the required creepage, clearance, exposed-pad connection, or maximum working voltage. Use the manufacturer layout and absolute-maximum-rating recommendations, maintain a controlled return plane, and place protection or discharge components where the application requires them rather than inferring safe spacing from package size alone.
Include acquisition settling time after each serial-interface state change because switch transitions can couple into downstream measurement paths. The documented low-charge-injection characteristic reduces injected disturbance, while 48 ohm on-resistance defines the signal-path impedance. Nevertheless, cable capacitance, PCB capacitance, and switch-node capacitance can still create ringing. Validate the complete transducer or sensor path with an oscilloscope and adjust sequencing, termination, or blanking intervals rather than relying only on nominal switching specifications.
Follow the exact supply pins, sequencing requirements, and decoupling values specified in the manufacturer datasheet. The supplied verified data identifies a digital interface and high-voltage CMOS switching array but does not provide supply voltage or current limits. Place required bypass capacitors at the designated package pins, keep digital return current separate from sensitive analog paths, and verify power-up behavior in hardware because a high-voltage switch may experience transient stress while its control interface is not yet valid.
Do not treat MAX14801CCM+, MAX14802CCM+, or MAX14803CCM+ as automatic drop-in replacements solely because they share the family and package class. The supplied comparison establishes related 16-channel high-voltage switching devices, but it does not provide their complete pin functions, voltage ratings, resistance, timing, or interface differences. Check each manufacturer datasheet, confirm unused-pin treatment and serial protocol, and perform a worst-case timing comparison before substituting any family member.
Información de cumplimiento
The supplied verified results do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the commercial-grade part is an analog interface IC rather than an explicitly automotive-qualified device.
