MAX14801CCM+ - 16-Channel High-Voltage Switch | Analog Devices
MPN: MAX14801CCM+ ✓ ActiveMAX14801CCM+ Overview
An analog switch is a semiconductor device that connects or isolates circuit nodes under digital control. The MAX14801CCM+ belongs to the analog switch family within the broader interface IC hierarchy, where multiplexers and switches route precision signals between sensors, amplifiers, converters, and test circuitry. Its low-charge-injection characteristic is especially relevant when switching analog signals whose timing accuracy or waveform integrity could otherwise be affected by injected charge.
The verified product information identifies the MAX14801CCM+ as a 16-channel, high-voltage switch with low charge injection and a digital interface. Its HVCMOS implementation supports the high-voltage switching function described for the MAX14800-MAX14803 family. The device is intended primarily for ultrasonic imaging and printer applications, where multiple high-voltage analog channels must be selected using a serial or otherwise digital control mechanism.
The 48-LQFP surface-mount package provides a compact solution for multi-channel analog routing while preserving individually accessible switch connections. Compared with mechanically selected high-voltage switches, the integrated digital control can simplify system sequencing and channel management. Exact voltage ratings, on-resistance, off leakage, bandwidth, channel capacitance, logic thresholds, and timing values must be confirmed in the manufacturer datasheet before final circuit design.
Typical uses include ultrasonic receiver and transmitter signal paths, high-voltage printer-head interfaces, diagnostic acquisition equipment, and industrial test systems requiring 16 controlled switching points. In an ultrasonic system, the switch can route multiple channels while a digital controller establishes the required connection sequence and minimizes the burden of discrete control circuitry.
The principal design consideration is ensuring that every driven logic pin and selected analog node stays within the device's verified voltage limits. Layout should preserve short analog traces, provide a stable ground reference, and prevent switching transients from coupling into sensitive neighboring nodes. Because the detailed electrical limits are not present in the supplied verified excerpts, designers should use the complete manufacturer datasheet for voltage, current, timing, and absolute-maximum-rating decisions.
This product page consolidates verified distributor identification, family-level analog-switch characteristics, same-package alternatives, and application-oriented design guidance. It separates confirmed attributes from parameters that still require datasheet verification, helping engineers evaluate the MAX14801CCM+ without treating unverified numerical claims as design data.

Typical Applications
MAX14801CCM+ is suitable for 6 applications: Ultrasonic Imaging Signal Routing, High-Voltage Printer Head Interface, Medical Diagnostic Acquisition Systems, Industrial Test and Measurement, High-Voltage Sensor Multiplexing, Automated High-Voltage Channel Sequencing.
Ultrasonic Imaging Signal Routing
The MAX14801CCM+ fits ultrasonic imaging systems requiring multiple high-voltage analog paths to be selected under digital control. Its verified family characteristics include 16 SPST channels, low charge injection, HVCMOS technology, and a 48-LQFP package. The switch can reduce the number of discrete high-voltage routing elements while allowing the controller to establish channel order and timing. Designers should place the device close to the routed nodes, maintain a continuous ground reference, and verify the actual signal amplitude, on-resistance, leakage, and switching time against the manufacturer datasheet before implementation.
Recommended
High-Voltage Printer Head Interface
The MAX14801CCM+ is relevant to printer-head interfaces because the MAX14800-MAX14803 family is explicitly identified for printer applications. Sixteen digitally controlled SPST channels provide a compact way to route multiple analog or drive-related signals, while low charge injection helps reduce unintended transients during channel changes. The 48-LQFP surface-mount package supports dense board layouts, but engineers must confirm the permitted voltage range, current, bandwidth, and logic levels for the exact printer architecture. PCB routing should minimize loop area and keep switching nodes away from sensitive feedback traces.
Recommended
Medical Diagnostic Acquisition Systems
The MAX14801CCM+ can support diagnostic acquisition front ends that require controlled routing of multiple high-voltage analog signals. Its 16-channel SPST architecture and digital interface allow an embedded controller to establish deterministic measurement paths without a mechanical selector. Low charge injection is valuable when the switched node influences timing-sensitive or high-impedance analog stages. The supplied evidence confirms the channel count, package, and family positioning but does not establish medical-system qualification. Signal limits, isolation requirements, leakage, and acquisition timing must therefore be validated against the complete datasheet and system safety requirements.
Recommended
Industrial Test and Measurement
The MAX14801CCM+ can organize a multi-point industrial test system by switching 16 analog connections through a digital control interface. This architecture is useful when the fixture or instrument must route signals sequentially among transducers, sensors, amplifiers, or stimulation nodes. The square 48-LQFP package provides a compact surface-mount implementation, and the SPST configuration supports straightforward channel isolation. Engineers should verify withstand voltage, leakage, bandwidth, and timing before using the switch as a precision measurement path, while also accounting for ground bounce and switching transients in the fixture PCB.
Recommended
High-Voltage Sensor Multiplexing
The MAX14801CCM+ is suitable for multiplexing architecture where several high-voltage sensor outputs must be presented to a shared analog processing chain. Sixteen SPST paths provide more channel density than discrete relays, while the digital interface permits the host controller to select routes deterministically. Low charge injection is especially useful when the muxed node feeds a high-impedance amplifier. Exact input capacitance, off-state isolation, on-state resistance, and common-mode limits were not present in the verified excerpts, so the sensor signal bandwidth and impedance must be checked against the complete manufacturer specification.
Recommended
Automated High-Voltage Channel Sequencing
The MAX14801CCM+ can serve as the central routing element in an automated sequencing system because it combines 16 SPST channels with digital control. A controller can command the desired channel while keeping the remaining paths isolated, reducing mechanical switching hardware and improving repeatability. HVCMOS process technology is explicitly associated with the family, while low charge injection helps preserve analog transitions. Before deployment, verify the control protocol, setup timing, input logic thresholds, and maximum switched voltage. The PCB should include adequate grounding and local bypass arrangements according to the manufacturer's recommendations once those values are confirmed.

Design Notes
Route switched analog nodes with short traces, a continuous reference plane, and minimal loop area. Because the MAX14801CCM+ provides 16 high-voltage SPST channels in one package, adjacent nets can couple through package and board parasitics. Keep sensitive inputs away from switching outputs, maintain symmetric grounding, and verify the complete manufacturer's layout guidance once the pin table and absolute-maximum ratings are available.
Evaluate charge injection, off-state leakage, on-resistance, capacitance, and bandwidth together when the switch feeds a high-impedance amplifier. Low charge injection is a verified family feature, but it does not by itself establish total settling time or usable bandwidth. Confirm those parameters in the complete datasheet and include the selected amplifier's input capacitance and noise requirements in the settling-time calculation.
Do not infer permissible switched-node or logic voltages from the phrase high-voltage. Check the MAX14801CCM+ absolute-maximum ratings, operating voltage, logic thresholds, and transient limits in the current manufacturer datasheet. The supplied excerpts do not provide numeric voltage ratings, so power-supply sizing and protection components must remain open design items until those values are verified.
Avoid treating MAX14800CCM+, MAX14802CCM+, and MAX14803CCM+ as automatically interchangeable with MAX14801CCM+ merely because they are related and use 48-pin packages. Verify pin names, control protocol, switched polarity, timing, voltage ratings, and channel behavior one-for-one. A board intended for a different family member must also be checked for enable, clock, latch, and power-pin differences.
Compliance Information
The supplied verified excerpts identify a commercial temperature grade but do not provide RoHS, REACH, halogen-free, conflict-minerals, or AEC-Q100 declarations. These statuses remain unknown and must be confirmed from current manufacturer documentation.
