MAX14806CCM+ 16-Channel High-Voltage Analog Switch
部品番号: MAX14806CCM+ ✓ 生産中MAX14806CCM+ 概要
A high-voltage analog switch is a semiconductor device that routes analog signals under digital control while supporting voltage levels and isolation requirements that exceed ordinary low-voltage signal switches. In the signal-chain hierarchy, the MAX14806CCM+ is an interface IC and analog switch, with application-level roles in ultrasound probe selection, bank switching, and high-voltage signal isolation.
The verified product information identifies sixteen high-voltage, low-charge-injection SPST switches, two independently controlled banks of eight channels, a digital control interface, and operation from -40°C to +85°C. These features make the device suitable for biplane and triplane ultrasonic probe arrangements, where multiple echo paths must be selected without changing the surrounding PCB layout. The low-charge-injection characteristic is particularly relevant when preserving small received ultrasound signals.
The MAX14806CCM+ uses a 200V process technology, while the exact supported signal-voltage limits, on-resistance across all operating conditions, channel leakage, control-logic levels, and timing values require confirmation from the manufacturer datasheet. The package is identified by distributors as a 48-LQFP (7x7 mm), while the manufacturer describes the device as a 48-pin TQFP package. The same-source cross-reference states that the MAX14806CCM+ is a drop-in replacement for the Supertex HV2731.
For ultrasound probe-bank selection, the device can replace mechanical or relay-based routing when the system requires digital control and low-charge-injection switching. In biplane imaging, two banks of eight channels can support the two probe banks. For triplane imaging, the switch can be integrated into a multiplexed receive architecture, subject to the detailed system timing and signal-integrity requirements.
When designing the PCB, reserve the exact 48-pin LQFP footprint and route control signals away from sensitive analog inputs. Confirm the absolute maximum signal voltage, supply requirements, input capacitance, charge injection, off isolation, and power dissipation in the manufacturer datasheet before committing the design. This page combines verified manufacturer and distributor information, drop-in cross-reference data, application guidance, and explicit markers for parameters that were not supplied in the source data.

主な用途
MAX14806CCM+ の用途: 6 件s: Biplane Ultrasound Probe Bank Selection, Triplane Ultrasound Receive Multiplexing, High-Voltage Relay Replacement, Ultrasound Probe Signal Multiplexer, Medical Imaging Signal Routing, Precision Analog Test and Measurement.
Biplane Ultrasound Probe Bank Selection
The MAX14806CCM+ fits biplane ultrasound probe interfaces because its 16 SPST channels are organized into two banks of eight, matching the two-bank structure commonly used to select receive paths from a biplane probe. According to the manufacturer datasheet, the device provides low charge injection and digital control, helping preserve small received ultrasound signals while replacing relay-based bank routing. The two banks can be selected by the imaging controller, reducing mechanical switching and keeping the routing network compact. PCB implementation should follow the 48-LQFP (7x7 mm) land pattern and provide clean grounding around the analog switch pins. Because the supplied excerpts do not state the complete control timing or absolute maximum signal voltage, those values must be verified in the manufacturer datasheet before connecting transducer echo signals.

Triplane Ultrasound Receive Multiplexing
The MAX14806CCM+ can support triplane ultrasound receive multiplexing by using its two banks of eight high-voltage SPST switches to organize multiple probe signal paths. The manufacturer datasheet specifically identifies bank selection in triplane ultrasound probes as an intended use. Its digital interface allows the imaging system to command the appropriate bank, while the low-charge-injection characteristic helps limit unwanted signal disturbance when switching. The device therefore offers a compact alternative to relay arrangements where board area and control repeatability matter. The exact maximum input voltage, control setup timing, and allowable switching frequency are not included in the verified excerpts, so the ultrasound acquisition timing and transducer excitation limits should be checked against the manufacturer datasheet before implementation.
おすすめ
High-Voltage Relay Replacement
The MAX14806CCM+ is suitable for replacing relay-based routing in high-voltage analog signal paths because it provides 16 high-voltage SPST channels with a digital interface and low charge injection. According to the manufacturer datasheet, relay replacement is an explicit application for the device. Semiconductor switching removes mechanical contacts and enables repeatable system-controlled selection, while the two-bank architecture can preserve separate routing groups. Designers should compare the relay's isolation, bandwidth, contact capacitance, and lifetime against the switch specifications before making a direct substitution. The verified excerpts identify 16 ohm on resistance and 200V process technology, but do not provide full isolation, leakage, power, or lifetime data; those parameters must be confirmed in the manufacturer datasheet.

Ultrasound Probe Signal Multiplexer
The MAX14806CCM+ can serve as a dedicated ultrasound probe signal multiplexer when the acquisition architecture requires many individually switched analog channels. According to the manufacturer datasheet, the device includes sixteen high-voltage, low-charge-injection SPST switches controlled by a digital interface. The 16-channel count allows probe elements or subarrays to be routed through a shared receiver chain, while the two banks of eight support structured selection. This use is especially useful where relay count, size, or switching consistency is problematic. Layout should keep the analog traces short and place decoupling and return paths according to the manufacturer recommendations. Before finalizing the design, verify the signal-voltage ceiling, input capacitance, switching delay, and off-isolation from the complete manufacturer datasheet.
おすすめ
Medical Imaging Signal Routing
The MAX14806CCM+ fits medical imaging systems that require controlled routing of high-value, high-voltage analog signals. Its 16 SPST channels, digital interface, low charge injection, and extended -40°C to +85°C temperature specification support ultrasound receiver and probe-bank architectures. According to the manufacturer datasheet, the two-bank organization is intended to reduce relay use in biplane and triplane probes. For medical equipment, circuit design must also account for the complete system safety, isolation, leakage, and qualification requirements; those product-level requirements are not contained in the supplied source excerpts. Engineers should verify the absolute maximum ratings and timing in the manufacturer datasheet and confirm the applicable medical-device requirements for the complete instrument rather than relying only on component-level information.
おすすめ
Precision Analog Test and Measurement
The MAX14806CCM+ can be used in test and measurement equipment where multiple analog paths must be switched under digital control. Its 16 SPST channels, 16 ohm listed on resistance, and low charge injection provide useful characteristics for instrumentation that routes measured or stimulated signals. According to the manufacturer datasheet, the high-voltage switching capability and digital interface make the device suitable beyond ultrasound when the system can remain within the device's absolute maximum ratings. Measurement accuracy still depends on signal frequency, off isolation, leakage, input capacitance, and source impedance, none of which are fully provided in the supplied excerpts. Use the manufacturer datasheet for those parameters, and place the analog switches close enough to preserve signal integrity while respecting the 48-LQFP layout constraints.

設計ノート
Use the 48-LQFP (7x7 mm) land pattern and preserve the manufacturer's recommended pin and thermal arrangement. Keep the 16 high-voltage analog paths as short and direct as practical, route digital control signals away from transducer and receiver traces, and provide a low-impedance return path for every switched channel. Because the complete pinout is not present in the supplied source data, do not infer pin assignments from package position; verify the numbered pinout in the manufacturer datasheet before routing power, ground, control, and analog nets.
The listed 16 ohm on resistance and low charge injection are important in ultrasound receive paths, but they do not alone determine usable bandwidth or signal integrity. Calculate the switch resistance against the source impedance and receiver input, and include the switch capacitance and routing capacitance in the bandwidth analysis. The supplied excerpts do not state input capacitance, off isolation, leakage, or switching time, so obtain those values from the manufacturer datasheet before setting gain, bandwidth, and settling-time requirements.
Do not interpret the use of 200V process technology as permission to apply 200V to every signal pin without checking the absolute maximum ratings. Confirm the supported signal-voltage range, supply requirements, control thresholds, and operating-current limits from the manufacturer datasheet. Also verify that the two control banks are sequenced within the device's timing limits; changing bank state during an acquisition window can corrupt echo data even if the hardware itself remains operational.
