Product details
Overview
MAX4684EBC-T10 from Maxim Integrated is a low-voltage, dual SPDT analog switch IC with 0.5Ω max NC on-resistance and 0.8Ω max NO on-resistance at +2.7V supply, 50ns turn-on time, and rail-to-rail signal handling-designed for speaker/headset switching and audio routing in battery-powered portable electronics.
For engineers reviewing the MAX4684EBC-T10 datasheet, MAX4684EBC-T10 pinout, MAX4684EBC-T10 application, or MAX4684EBC-T10 equivalent, key selection criteria include on-resistance matching (≤0.06Ω), break-before-make timing (2ns), 1.8V logic compatibility, and UCSP-12 package footprint constraints.
Technical Context
The MAX4684EBC-T10 implements two independent SPDT analog switches with asymmetrical RON paths: NC path optimized for lower resistance (0.5Ω max), NO path at 0.8Ω max-enabling differential load handling in headset jack detection and internal/external speaker routing. Its BiCMOS process ensures stable RON flatness (≤0.15Ω) over full 0–V+ signal range.
Switching is controlled by two 1.8V-compatible digital inputs (VIH = 1.4V, VIL = 0.5V) referenced to GND, with break-before-make action preventing signal shorting during state transitions. All analog terminals (NO_, NC_, COM_) support bidirectional rail-to-rail signals up to V+ (+1.8V to +5.5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| NC RON (max) | 0.5Ω at +2.7V - enables low-loss connection for high-current NC paths like main speaker output |
| NO RON (max) | 0.8Ω at +2.7V - balances performance and layout symmetry for auxiliary NO paths like headset detection |
| RON match | ≤0.06Ω between channels - critical for stereo channel tracking and balanced audio switching |
| tON/tOFF | 50ns/40ns at +3V - supports fast audio mute/unmute and dynamic routing without audible artifacts |
| Supply range | +1.8V to +5.5V - allows direct integration with Li-ion, coin-cell, and 3.3V/5V system rails |
| Logic compatibility | 1.8V input thresholds - interoperates with modern low-voltage MCUs without level-shifting |
| Off-isolation | −64dB at 100kHz - suppresses crosstalk between active and inactive audio paths |
Pinout & Package
The MAX4684EBC-T10 is housed in a 12-bump, 0.5mm-pitch UCSP package measuring 2.0mm × 1.50mm, with exposed die attach area but no thermal pad. Bump layout follows standard UCSP 4×3 array; bump assignment is validated per Maxim's official pin diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| NC1, NC2 | Normally closed analog terminal | Low-resistance path closed when IN_ = 0; used for default audio output routing |
| NO1, NO2 | Normally open analog terminal | Path closed only when IN_ = 1; enables selective signal insertion (e.g., headset detection) |
| COM1, COM2 | Common analog terminal | Bidirectional I/O node connecting to source/sink; must be routed with controlled impedance |
| IN1, IN2 | Digital control input | Active-low logic interface; accepts 0.5V/1.4V thresholds independent of V+ |
| V+ | Positive supply | Single power rail for analog and digital sections; decoupling required within 2mm |
| GND | Ground reference | Return path for all analog and digital currents; must connect directly to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical RON | 0.5Ω (NC) / 0.8Ω (NO) enables optimized current handling for primary vs. secondary audio paths |
| RON flatness | ≤0.15Ω over full 0–V+ range ensures consistent THD (<0.03%) across audio signal swing |
| Break-before-make | 2ns guaranteed delay prevents momentary short-circuit during channel switching |
| Low leakage | ≤1nA at +25°C minimizes DC offset drift in precision sensor or bias networks |
| UCSP footprint | 2.0mm × 1.50mm area reduces PCB space by >60% vs. µMAX or TDFN alternatives |
Applications
| Speaker Headset Switching | MP3 Player Audio Routing |
|---|---|
Use Scenario: Automatically routes audio between built-in speaker and 3.5mm headset jack upon plug detection. IC Role / Device Role / Timing Role: Dual SPDT switch isolates speaker path while enabling headset path with sub-50ns transition.

IC Role / Device Role / Timing Role: Bidirectional analog switch handling AC-coupled audio signals up to 20kHz with <0.03% THD. Use Value: Maintains signal integrity across multiple sources using rail-to-rail operation and −68dB crosstalk suppression. |
| Power Routing in Wearables | Relay Replacement in IoT Sensors |

IC Role / Device Role / Timing Role: Low-RON analog switch acting as solid-state power gate with 300mA continuous rating. Use Value: Replaces discrete MOSFETs with integrated control, reducing BOM count and enabling 1.8V MCU direct drive without gate drivers. | Use Scenario: Isolates sensor excitation lines or reference voltages in industrial condition-monitoring nodes. IC Role / Device Role / Timing Role: High-off-isolation (−64dB) switch preventing leakage-induced measurement error in µA-level sensor circuits. Use Value: Achieves <1nA off-leakage at +25°C, enabling accurate low-current transducer interfacing without calibration drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4685EBC+T | Symmetric 0.8Ω RON on both NC and NO paths; identical UCSP-12 package and timing | Better suited for balanced dual-path routing (e.g., stereo channel swapping) where asymmetry is unnecessary | Select MAX4685EBC+T when NC/NO load matching is required; MAX4684EBC-T10 preferred for headset/speaker prioritization |
| TMUX1574RTER | 0.5Ω RON, 3.6V max supply, 1.2V logic compatible, 10-pin WQFN package (2.5mm × 2.5mm) | Larger footprint, higher supply limit, but lacks break-before-make guarantee and UCSP size advantage | Choose TMUX1574RTER only if >3.6V operation or 1.2V logic interface is mandatory; otherwise MAX4684EBC-T10 offers superior size/performance tradeoff |
Compared with MAX4685EBC+T and TMUX1574RTER, the MAX4684EBC-T10 uniquely delivers asymmetrical RON in the smallest UCSP footprint, making it optimal for space-constrained portable audio where NC path efficiency is critical.

FAQ
What is the maximum supply voltage rating for the MAX4684EBC-T10?
The MAX4684EBC-T10 has an absolute maximum supply voltage (V+) of +6V, but its specified operating range is +1.8V to +5.5V. Operation above +5.5V risks permanent damage and violates the device's qualified electrical specifications. For reliable long-term use in portable systems, design with V+ ≤ +5.5V and implement proper sequencing (apply V+ before analog signals).
Does the MAX4684EBC-T10 support bidirectional analog signal flow?
Yes, the MAX4684EBC-T10 supports fully bidirectional signal flow on all analog terminals (NO_, NC_, COM_). Each switch channel passes signals equally well in either direction, enabling flexible routing in audio, sensor, and power applications without polarity constraints-verified by rail-to-rail signal handling and symmetric on-resistance behavior.
How does the break-before-make timing of the MAX4684EBC-T10 prevent signal shorting?
The MAX4684EBC-T10 guarantees a minimum 2ns break interval between opening one path and closing the other during switching transitions. This prevents momentary short-circuit conditions between NC and NO terminals, which is essential in audio routing to avoid pops/clicks and in power routing to protect downstream circuitry from transient faults.
Can the MAX4684EBC-T10 be used with a 1.8V logic controller?
Yes, the MAX4684EBC-T10 features 1.8V logic-compatible inputs with VIH = 1.4V (min) and VIL = 0.5V (max), allowing direct interface to 1.8V microcontrollers without level shifters. Input leakage remains ≤±1µA, minimizing loading on low-power GPIOs-confirmed across the full −40°C to +85°C temperature range.
What is the thermal pad configuration for the MAX4684EBC-T10 UCSP package?
Unlike TDFN variants, the MAX4684EBC-T10 UCSP package does not include an exposed thermal pad (EP). It uses a 12-bump chip-scale structure with solder bumps on a silicon die; thermal dissipation relies on conduction through the V+ and GND bumps into the PCB copper. No EP connection is required or recommended for this specific variant.
