Product details
Overview
MAX4737EBE+T from Maxim Integrated is a quad single-pole/single-throw (SPST) analog switch optimized for USB 1.1 and audio signal routing. It operates from a single +1.8V to +5.5V supply, delivers 4.5Ω max on-resistance at +3V, 0.4Ω max RON matching, and <80ns turn-on time at +2.7V - enabling low-distortion, rail-to-rail signal switching in portable audio interfaces and battery-powered USB peripherals.
For engineers reviewing the MAX4737EBE+T datasheet, MAX4737EBE+T pinout, MAX4737EBE+T application, or MAX4737EBE+T equivalent, this page provides verified package mapping (16-bump UCSP), confirmed SPST NO-only topology, real-world AC performance metrics (–80dB crosstalk at 10MHz, 300MHz –3dB bandwidth), and validated alternatives for USB/audio analog switching designs.
Technical Context
The MAX4737EBE+T implements four independent normally open (NO) analog switches using CMOS process technology, supporting bidirectional signal flow with rail-to-rail analog voltage handling (GND to V+). Its break-before-make architecture is not implemented - unlike the MAX4739 - and it guarantees operation across –40°C to +85°C with <0.5nA leakage at +25°C.
Designed specifically for low-voltage signal integrity, it achieves 2ns max differential skew, 15pF on-channel capacitance, and 0.03% THD at 600Ω load - all while maintaining logic compatibility with +1.8V CMOS inputs even when powered from +2.7V to +3.6V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4.5Ω at +3V supply - ensures minimal signal attenuation and voltage drop in audio/USB data paths |
| RON Matching (max) | 0.4Ω between channels at +3V - critical for balanced multi-channel audio routing without level mismatch |
| Turn-On Time (max) | 80ns at +2.7V - supports USB 1.1 full-speed (12Mbps) timing with margin |
| Crosstalk (at 10MHz) | –80dB - prevents audible interference or data corruption between adjacent switched audio/data lines |
| Off-Isolation (at 10MHz) | –55dB - maintains signal separation between inactive and active channels in shared analog buses |
| Bandwidth (–3dB) | >300MHz - preserves high-frequency content in fast-switching applications like composite video or high-fidelity audio |
| Supply Range | +1.8V to +5.5V - enables direct integration into Li-ion (3.3V/3.7V) and USB bus-powered (5V) systems |
Pinout & Package
MAX4737EBE+T is packaged in a 16-bump ultra-thin chip-scale package (UCSP™), occupying only 2mm × 2mm board area with 0.5mm bump pitch. The package is RoHS-compliant and designed for reflow soldering with infrared (220°C) or vapor-phase (215°C) profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NO1–NO4 | Analog output (normally open) | Four independent switched outputs; each connects to COMx only when corresponding INx is high |
| COM1–COM4 | Analog common terminal | Bidirectional signal path - accepts input or delivers output depending on system topology |
| IN1–IN4 | Digital control input | +1.8V logic compatible; accepts up to +5.5V regardless of V+, enabling mixed-supply interface |
| V+ | Positive supply | Single power rail for analog and digital sections; bypassing with 0.1µF to GND required for noise immunity |
| GND | Ground reference | Digital ground connection point; must be low-impedance to minimize switching noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 signal switching compliance | Validated for 12Mbps full-speed data with <2ns propagation delay and <0.5ns skew change |
| Rail-to-rail analog signal handling | Supports signals from GND to V+ without clipping - essential for unbuffered audio and sensor interfaces |
| Low on-channel capacitance | 15pF typical - minimizes loading on high-impedance sources and preserves signal rise/fall times |
| Ultra-low leakage current | <0.5nA at +25°C - prevents DC offset drift in precision sample-and-hold or medical sensor front-ends |
| High off-isolation | –55dB at 10MHz - suppresses unwanted coupling in multi-source audio mixers or multiplexed data acquisition |
Applications
| USB Peripheral Switching | Portable Audio Routing |
|---|---|
|
Use Scenario: Selecting between multiple USB upstream ports in a dock or hub controller. IC Role / Device Role / Timing Role: Quad SPST analog switch routing D+ and D– lines with matched RON and low skew. Use Value: Maintains USB 1.1 signal integrity with <2ns skew and >300MHz bandwidth - no protocol-level retraining needed. |
Use Scenario: Dynamic channel selection in Bluetooth headphones with dual DAC outputs. IC Role / Device Role / Timing Role: Low-RON, low-capacitance switch enabling seamless stereo channel routing without pop/click artifacts. Use Value: 4.5Ω RON and 0.03% THD preserve audio fidelity; 15pF CON avoids high-frequency roll-off in 20kHz+ content. |
| Low-Voltage Data Acquisition | Sample-and-Hold Circuits |
|
Use Scenario: Multiplexing sensor inputs (e.g., thermocouples, RTDs) in handheld test equipment. IC Role / Device Role / Timing Role: Precision analog switch providing low-leakage (<0.5nA), flat-RON signal path before ADC front-end. Use Value: 1.2Ω RON flatness over signal range minimizes gain error; low charge injection (5pC) prevents hold capacitor disturbance. |
Use Scenario: Acquiring fast transient waveforms in oscilloscope front-ends or power quality analyzers. IC Role / Device Role / Timing Role: High-speed switch isolating sampling capacitor during acquisition phase with sub-80ns tON. Use Value: <40ns tOFF enables rapid hold-to-acquire transition; low crosstalk (–80dB) prevents feedthrough from adjacent channels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4737ETE | Same electrical specs; packaged in 4mm × 4mm 16-pin thin QFN instead of UCSP | Preferred where thermal dissipation >659mW is required or PCB assembly lacks UCSP reflow capability | Select MAX4737ETE for higher-power or legacy SMT lines; MAX4737EBE+T for space-constrained portable designs |
| TS5A4624DCKR | 4.8Ω RON (max), 16-pin SC70 package, 300MHz bandwidth, but only specified down to –40°C (not guaranteed at TMAX) | Suitable for commercial-temp consumer audio, not industrial-grade USB or data acquisition | Choose TS5A4624DCKR for cost-sensitive, non-extended-temp applications; MAX4737EBE+T for full –40°C to +85°C reliability |
Compared with MAX4737ETE and TS5A4624DCKR, the MAX4737EBE+T uniquely combines UCSP's 2mm × 2mm footprint with guaranteed –40°C to +85°C operation, 0.4Ω RON matching, and USB 1.1 compliance - making it optimal for miniaturized, ruggedized analog switching where board area and temperature margin are critical.

FAQ
What is the maximum operating temperature range for the MAX4737EBE+T?
The MAX4737EBE+T is fully specified and guaranteed over an operating temperature range of –40°C to +85°C. This range is validated per the device's Absolute Maximum Ratings and Electrical Characteristics tables, with thermal derating applied above +70°C for continuous power dissipation (659mW at +70°C, derated by 8.3mW/°C).
Does the MAX4737EBE+T support rail-to-rail analog signal switching?
Yes, the MAX4737EBE+T supports rail-to-rail analog signal handling - signals on COM_, NO_, and NC_ pins can swing from GND to V+ without clipping or increased distortion. This is explicitly confirmed in the Electrical Characteristics table under "Analog Signal Range" and reinforced in the Applications Information section.
Is the MAX4737EBE+T pin-compatible with the MAX4738EBE+T or MAX4739EBE+T?
No, the MAX4737EBE+T is not pin-compatible with MAX4738EBE+T or MAX4739EBE+T. While all three share the same 16-bump UCSP package outline, their pin functions differ: MAX4737EBE+T has four NO terminals, MAX4738EBE+T has four NC terminals, and MAX4739EBE+T mixes two NO and two NC - as shown in the Pin Descriptions table and functional diagrams.
What is the typical on-channel capacitance of the MAX4737EBE+T?
The typical on-channel capacitance (CON) of the MAX4737EBE+T is 15pF, measured at f = 1MHz per Figure 6 in the datasheet. This value is consistent across all four channels and directly impacts high-frequency signal integrity and settling time in fast-switching applications.
Can the digital control inputs of the MAX4737EBE+T accept voltages higher than the V+ supply?
Yes, the digital control inputs (IN1–IN4) of the MAX4737EBE+T accept logic signals up to +5.5V regardless of the V+ supply voltage - for example, they can be driven with +5V logic while V+ is at +3.3V. This is documented in the Applications Information section and confirmed in the Absolute Maximum Ratings table.
