MAX4850ETE+T - Dual SPDT Analog Switch | Maxim Integrated
部品番号: MAX4850ETE+T ✓ 生産中MAX4850ETE+T 概要
An analog switch is a semiconductor device that connects or disconnects signal paths under digital control. The MAX4850ETE+T belongs to the analog-switch hierarchy within interface ICs: each SPDT path can route a common signal toward one of two external nodes, while the companion control logic determines which branch is connected. This capability is useful when a system must route audio, data, test, or control signals without changing the physical layout of the printed circuit board.
The MAX4850ETE+T provides two switch channels in one compact 16-TQFN package. Its over-rail signal-handling characteristic allows the switch to remain operational when signal levels approach or extend beyond the supply rails, a useful condition in systems where transitions can overshoot nominal voltage ranges. The small 3 mm by 3 mm footprint also reduces board area compared with discrete switch implementations.
This device is categorized as a high-bandwidth analog switch IC. Its two SPDT channels support signal-path multiplexing where one common input must be routed between alternative destinations. Such architecture is frequently encountered in audio equipment, USB-interface routing, test systems, communication modules, and control boards that require compact, electronically controlled routing.
Typical uses include selecting an audio source, directing signals through an interface module, switching USB-related signal paths, and implementing compact test fixtures. The industrial temperature grade and surface-mount construction suit professionally designed equipment that must combine multiple routed channels without allocating separate packages for each switch.
Designers should verify supply voltage, signal swing, bandwidth, on-resistance, leakage, and channel logic polarity against the manufacturer datasheet for the exact operating point. Because the TQFN package has a compact exposed-pad construction, PCB thermal management and soldering-process controls should follow the manufacturer’s land-pattern and reflow guidance.
This page organizes the exact package, channel, mounting, and ordering information for MAX4850ETE+T while adding engineering-focused comparisons and application guidance. It helps engineers identify the switch function, verify the footprint, and assess the signal-routing use cases before beginning board-level design.

主な用途
MAX4850ETE+T の用途: 6 件s: Audio Source Selection, USB Interface Signal Routing, Test and Measurement Fixture, Communication Signal Multiplexing, Industrial Control Signal Routing, Mixed-Signal Board Configuration.
Audio Source Selection
The MAX4850ETE+T fits compact audio-source selection because it provides two independent SPDT paths in one 16-TQFN package. According to the manufacturer datasheet, the device combines a high-bandwidth analog-switch architecture with over-rail signal handling. Each common audio node can be steered toward one of two destinations under logic control, reducing the need for separate relay or discrete-switch packages. The design must verify channel bandwidth, on-resistance, off isolation, distortion, and allowable signal amplitude against the actual source impedance and audio bandwidth. Its 3 mm by 3 mm footprint also leaves more board area for power, conversion, and storage circuitry in compact audio equipment.
おすすめ
USB Interface Signal Routing
The MAX4850ETE+T can support low-rate or control-related USB signal routing when the selected path must be switched electronically. According to the manufacturer datasheet, the device offers two SPDT channels, over-rail signal handling, and a high-bandwidth analog-switch implementation. The common terminal of each channel may connect to one of two alternative USB-associated nodes, allowing board-level source selection or test routing. For data-bearing USB paths, engineers should confirm insertion loss, capacitance, off isolation, bandwidth, and logic compatibility before implementation. The compact 16-TQFN (3x3) package is particularly useful where connector placement or signal-source selection must be reorganized without adding multiple switch footprints.
おすすめ
Test and Measurement Fixture
The MAX4850ETE+T is useful in a compact automated test fixture where two SPDT paths must connect one measurement source to alternative test nodes. According to the manufacturer datasheet, the device supports over-rail signal handling and is packaged as a surface-mount 16-TQFN measuring 3 mm by 3 mm. Electronic routing avoids moving connectors or using bulky mechanical selectors while the 3 x 3 mm footprint supports dense fixture boards. Before selecting the part, verify input capacitance, leakage, on-resistance, switching timing, and the maximum voltage applied by the test system. Digital control should keep inactive terminals in defined states, and the PCB should provide adequate clearance around the compact exposed-pad land pattern.
おすすめ
Communication Signal Multiplexing
The MAX4850ETE+T can multiplex communication-board signals when two SPDT paths are sufficient and over-rail excursions may occur. According to the manufacturer datasheet, it is a high-bandwidth analog switch with two selectable channels and over-rail signal handling. A common signal can therefore be directed toward one of two line-driver, receiver, or termination networks, helping conserve connector space and reduce board area. The implementation must preserve signal integrity by checking bandwidth, off isolation, capacitance, and channel behavior at the operating data rate. Short traces and a deliberate return path are important, particularly when the switch sits near high-speed edges. Logic levels and supply sequencing should also follow the manufacturer’s recommended operating conditions.
おすすめ
Industrial Control Signal Routing
The MAX4850ETE+T suits industrial control boards that require two compact, electronically selected analog paths. According to the manufacturer datasheet, the device is identified as industrial grade, provides two SPDT channels, and handles over-rail signals in a surface-mount 16-TQFN package. It can route a control or sensor signal toward separate conditioning, monitoring, or actuator-interface sections while preserving a compact layout. Before deployment, verify the exact operating-temperature limits, supply range, logic thresholds, leakage, and maximum continuous signal level. Industrial systems should also evaluate transient protection, grounding, and fault-state behavior at the connected nodes. The small package reduces physical footprint, although correct exposed-pad soldering remains essential for assembly reliability.
おすすめ
Mixed-Signal Board Configuration
The MAX4850ETE+T can implement configurable mixed-signal routing where one source must reach one of two differently conditioned destinations. According to the manufacturer datasheet, the dual SPDT architecture supports two independent switching decisions in a 3 mm by 3 mm 16-TQFN package. This arrangement is useful for selecting between a direct analog path and an alternative filtering, sensing, or calibration network. The over-rail characteristic is helpful when node voltages can overshoot nominal rails, but the actual excursion and duration must remain within the manufacturer’s operating conditions. PCB design should minimize trace length around the switch, maintain a continuous ground reference, and follow the manufacturer’s thermal-pad land pattern to preserve both signal behavior and assembly yield.

設計ノート
Follow the manufacturer’s TQFN land pattern for the MAX4850ETE+T, including the exposed thermal pad, solder-mask openings, and paste area. The package is only 3 mm by 3 mm, so small placement errors can couple into adjacent high-impedance nodes. Route each switched signal away from clocks, switching regulators, and unrelated analog inputs, and preserve a continuous ground reference beneath the device.
Verify bandwidth, on-resistance, off isolation, capacitance, leakage, and logic thresholds in the manufacturer datasheet before assigning the MAX4850ETE+T to a precision or high-speed path. Its two SPDT channels make routing flexible, but switch performance depends on source impedance, load impedance, trace length, and return-path continuity. Keep traces short and use a quiet reference plane when the routed signal is sensitive to crosstalk or switching transients.
Do not treat the MAX4850ETE+T as a power switch. Its SPDT function is intended for signal routing, and the connected signal amplitude, current, bandwidth, and transient limits must remain within the manufacturer’s operating conditions. Over-rail handling does not authorize unlimited voltage exposure. Confirm the absolute-maximum ratings and check that inactive or disconnected nodes cannot float into a state that disturbs the active signal path.
