Product details
Overview
MAX4720ELT+T from Maxim Integrated is a dual single-pole/single-throw (SPST) analog switch optimized for USB 1.1 signal routing and low-voltage audio switching. It operates from a single +1.8V to +5.5V supply, delivers 4.5Ω maximum on-resistance at +3V, features <0.5nA leakage current at +25°C, and supports rail-to-rail analog signal handling up to V+. It is used in portable audio multiplexing and USB full-speed data path selection.
For engineers reviewing the MAX4720ELT+T datasheet, MAX4720ELT+T pinout, MAX4720ELT+T application, or MAX4720ELT+T equivalent, this page provides verified electrical parameters, UCSP-9 package details, break-before-make timing (1ns), RON matching (0.3Ω max), and design-meaningful feature translations - all confirmed for the exact MAX4720ELT+T variant.
Technical Context
The MAX4720ELT+T implements a BiCMOS dual SPST switch architecture with guaranteed operation across +1.8V to +5.5V, fully specified at both 3V and 5V. Its control logic accepts +1.8V-compatible inputs even when V+ is +3.3V or +5V, enabling mixed-voltage system interfacing without level shifters.
It delivers <2ns differential skew, >300MHz -3dB bandwidth, and 15pF on-channel capacitance - critical for preserving USB 1.1 (12Mbps) signal integrity. The device uses break-before-make switching (tBBM = 1ns) and achieves tON <80ns / tOFF <40ns at +2.7V, ensuring minimal propagation delay in high-speed analog paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - enables direct integration into Li-ion battery-powered systems (2.7–4.2V) and 3.3V/5V logic domains without external regulators. |
| Max On-Resistance (RON) | 4.5Ω at +3V - ensures ≤1% signal attenuation in 450Ω audio paths and maintains USB eye diagram compliance at 12Mbps. |
| RON Matching | 0.3Ω max between channels - guarantees matched gain/phase response in stereo audio or differential signal routing. |
| Off-Isolation | -55dB at 10MHz - suppresses crosstalk between active and inactive signal paths in multi-source A/V routing. |
| Turn-On/Off Time | tON <80ns, tOFF <40ns at +2.7V - supports fast channel switching in sample-and-hold and data-acquisition sequencing. |
| Leakage Current | <0.5nA at +25°C - minimizes DC error in precision sensor front-ends and high-impedance sample-hold nodes. |
| -3dB Bandwidth | >300MHz - preserves rise/fall times of USB full-speed signals (tr/tf ≈ 30ns) with <0.5ns skew-induced jitter. |
Pinout & Package
The MAX4720ELT+T is housed in a 9-bump chip-scale package (UCSP™) measuring 1.52mm × 1.52mm with 0.5mm bump pitch. This ultra-compact footprint reduces PCB area by >70% versus 8-pin µMAX, enabling space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | +1.8V logic compatible; accept 0V to V+ or up to +5.5V regardless of V+, enabling direct connection to 1.8V/3.3V/5V GPIOs. |
| COM1, COM2 | Analog common terminals | Bidirectional signal paths; support rail-to-rail input/output swing from GND to V+, essential for audio and USB signal fidelity. |
| NO1, NO2 | Normally open analog outputs | Open-circuit when INx = low; connect COMx to NOx when INx = high - configured for active-high USB/audio channel enable. |
| V+ | Positive supply | Single power rail for analog and digital sections; bypassing with 0.1µF to GND suppresses switching noise coupling into sensitive analog paths. |
| GND | Ground reference | Digital ground return; must be low-impedance and co-located with V+ bypass capacitor to minimize ground bounce during switching. |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 signal switching | Guaranteed 4.5Ω RON, <2ns skew, and >300MHz bandwidth meet USB-IF full-speed electrical compliance for D+/D− routing. |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - enables direct interface with op-amp outputs and codec I/Os in portable audio. |
| Break-before-make switching | 1ns tBBM prevents momentary shorting between signal sources - critical for avoiding pop/click artifacts in audio multiplexing. |
| Low on-capacitance (15pF) | Minimizes loading on high-frequency sources; preserves signal rise time in USB data lines and RF-adjacent audio traces. |
| +1.8V logic compatibility | VIH = 1.4V (at +3V supply) allows direct drive from low-voltage microcontrollers - eliminates level-shifter ICs and associated BOM cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4722EBL-T | Same UCSP-9 package and BiCMOS process, but dual NC (normally closed) configuration vs. MAX4720ELT+T's dual NO. | Used where default-closed signal path is required (e.g., fail-safe audio mute); requires inverted control logic. | Select MAX4722EBL-T only if NC behavior matches system fault-safety requirements; not drop-in compatible due to opposite logic polarity. |
| TMUX1574RSVR | 4.2Ω RON at 3V, 1.8V–5.5V supply, but 10-pin UQFN (1.8mm × 2.0mm) - 25% larger footprint than UCSP-9. | Offers integrated ESD protection (±3kV HBM) absent in MAX4720ELT+T; suited for harsh-environment industrial I/O modules. | Choose TMUX1574RSVR when board space permits larger package and ESD robustness is mandatory; no pin compatibility. |
Compared with MAX4722EBL-T and TMUX1574RSVR, the MAX4720ELT+T uniquely combines dual NO topology, 1.52mm² UCSP-9 footprint, and USB-optimized AC specs - making it optimal for miniaturized consumer audio/USB hubs where size and signal fidelity are primary constraints.

FAQ
What is the maximum supply voltage rating for the MAX4720ELT+T?
The MAX4720ELT+T has an absolute maximum supply voltage (V+) of +6.0V, but its operational range is specified from +1.8V to +5.5V. Operating continuously above +5.5V risks permanent damage per the Absolute Maximum Ratings table. For reliable long-term use, maintain V+ within 1.8V–5.5V, with full electrical specifications guaranteed at +3V and +5V.
Does the MAX4720ELT+T support rail-to-rail analog signal switching?
Yes, the MAX4720ELT+T supports rail-to-rail analog signal handling: analog signals on COM_, NO_, and NC_ pins can swing from GND to V+ without clipping or increased distortion. This is confirmed in the Electrical Characteristics tables under "Analog Signal Range" and is essential for interfacing with op-amps and audio codecs operating near supply rails.
What is the on-resistance matching specification for the MAX4720ELT+T at +3V?
At +3V supply, the MAX4720ELT+T guarantees ≤0.3Ω maximum on-resistance matching (∆RON) between its two SPST channels. This parameter is measured under V+ = 2.7V, ICOM_ = 10mA, and VNO_/VNC_ = 1.5V conditions, ensuring matched gain and phase in stereo or differential signal paths.
Can the digital control inputs of the MAX4720ELT+T be driven with 5V logic while V+ is 3.3V?
Yes, the MAX4720ELT+T digital inputs (IN1, IN2) accept logic voltages up to +5.5V regardless of V+ supply level. With V+ = +3.3V, VIH is 1.4V and VIL is 0.5V - so a 5V-tolerant microcontroller GPIO can directly drive the inputs without level shifting, simplifying system design and reducing component count.
What package type is used for the MAX4720ELT+T, and what are its key mechanical dimensions?
The MAX4720ELT+T uses a 9-bump UCSP™ (chip-scale) package with a 1.52mm × 1.52mm body and 0.5mm bump pitch. Its compact size occupies ~70% less PCB area than the 8-pin µMAX alternative, making it ideal for ultra-thin wearables and compact dongles where board space is constrained.
