Product details
Overview
MAX4741EUA+TGA5 from Maxim Integrated is a dual single-pole/single-throw (SPST) analog switch with two normally open (NO) channels, designed for low-voltage signal routing in battery-powered and portable systems. It operates from a single +1.6V to +3.6V supply, delivers 0.8Ω max on-resistance at +3V, supports rail-to-rail analog signals, and achieves 24ns turn-on / 16ns turn-off times. It is used in audio/video routing and low-voltage data-acquisition circuits where low power and high channel matching are critical.
For engineers reviewing the MAX4741EUA+TGA5 datasheet, MAX4741EUA+TGA5 pinout, MAX4741EUA+TGA5 application, or MAX4741EUA+TGA5 equivalent, key selection criteria include on-resistance flatness (0.18Ω max), 1.8V CMOS logic compatibility at +3V supply, 150mA continuous current handling, and µMAX package thermal performance (362mW at +70°C).
Technical Context
The MAX4741EUA+TGA5 uses CMOS switch architecture enabling bidirectional, rail-to-rail analog signal switching across GND to V+. Its dual NO configuration is controlled by independent digital inputs (IN1, IN2), each compatible with 1.8V logic thresholds when powered from +3V.
It features matched on-resistance (0.08Ω max difference between channels) and low charge injection (28pC), minimizing signal transient errors during switching-critical for precision data acquisition and audio paths where THD remains below 0.02% over 20Hz–20kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.8Ω max at +3V supply - enables <100mV drop at 125mA, supporting high-fidelity analog routing |
| RON Matching | 0.08Ω max - ensures consistent gain/attenuation across dual channels in differential or parallel paths |
| RON Flatness | 0.18Ω max - maintains stable impedance over full 0–3V analog signal range, reducing distortion |
| Switching Speed | tON = 24ns, tOFF = 16ns max - supports >10MHz bandwidth signal routing without timing skew |
| Supply Range | +1.6V to +3.6V - allows direct integration with Li-ion, coin-cell, and low-power MCU I/O domains |
| Logic Compatibility | 1.8V CMOS input threshold at +3V supply - interfaces directly with 1.8V/3.3V digital controllers without level shifters |
| Leakage Current | ±5nA max COM/NO off-leakage - preserves signal integrity in high-impedance sensor front-ends |
Pinout & Package
The MAX4741EUA+TGA5 is housed in an 8-pin µMAX® package (U8-1), measuring 3.05mm × 3.05mm × 1.05mm, with exposed pad for thermal enhancement and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO2 | Normally open analog terminals - connect only when respective INx is high; isolated otherwise |
| 2, 6 | COM1, COM2 | Common analog ports - bidirectional signal path shared between NO and internal switch element |
| 3, 7 | IN2, IN1 | Digital control inputs - TTL/CMOS-compatible; drive switch state independently per channel |
| 4 | GND | Analog/digital ground reference - must be low-impedance for leakage and noise control |
| 5 | V+ | Positive supply - powers analog switch core and logic interface; bypass with 0.1µF to GND |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input range without clipping or increased RON - essential for full-scale sensor or audio signals |
| Ultra-low quiescent power | <1µW supply current - extends battery life in always-on portable instrumentation |
| High-current capability | 150mA continuous per channel - drives headphones, transducers, or multiplexed ADC inputs directly |
| Low charge injection | 28pC typical - minimizes voltage glitch on COM during switching, critical for precision sampling |
| Off-isolation & crosstalk | -55dB off-isolation and -110dB crosstalk at 1MHz - prevents signal bleed between channels in mixed-signal PCBs |

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 |
|---|---|---|---|
| MAX4741EKA+T | SOT23-8 package (3.0mm × 3.0mm), higher thermal resistance (7.52mW/°C derating), same electrical specs | Better suited for manual assembly or legacy SOT23 footprints; lower power dissipation margin than µMAX | Select when board space allows larger footprint or reworkability is prioritized over thermal density |
| TMUX1574RTER | 0.5Ω max RON at 3.3V, 1.8V logic compatible, but 30ns tON/tOFF and no guaranteed -40°C to +85°C spec | Higher bandwidth (150MHz) but looser timing specs; not qualified for extended industrial temp range | Choose for cost-sensitive consumer designs requiring lower RON, accepting reduced timing consistency and temp coverage |
Compared with MAX4741EUA+TGA5, the MAX4741EKA+T offers identical switching performance in a more serviceable package, while the TMUX1574RTER trades guaranteed industrial temperature operation and tighter timing for lower on-resistance-making the MAX4741EUA+TGA5 optimal for thermally constrained, mission-critical portable systems.

FAQ
What is the maximum continuous current rating for each channel of the MAX4741EUA+TGA5?
The MAX4741EUA+TGA5 supports 150mA continuous current per channel (COM, NO). This rating is validated across the full -40°C to +85°C operating range and is limited by package thermal resistance (362mW at +70°C for the µMAX package). Exceeding this current risks thermal shutdown or long-term reliability degradation, especially under sustained high RON conditions.
Does the MAX4741EUA+TGA5 support rail-to-rail analog signal switching?
Yes, the MAX4741EUA+TGA5 supports rail-to-rail analog signal switching from GND to V+, with minimal variation in on-resistance across the full range. At +3V supply, RON flatness is specified at 0.18Ω max, ensuring signal integrity for DC-coupled sensors and audio paths without clipping or gain nonlinearity.
Can the MAX4741EUA+TGA5 operate from a +1.8V supply, and what are the key trade-offs?
Yes, the MAX4741EUA+TGA5 operates from +1.6V to +3.6V. At +1.8V, on-resistance increases to 2.5Ω max, turn-on/turn-off times slow to 35ns/25ns max, and logic thresholds shift to VIH = +1.0V/VIL = +0.4V. These trade-offs maintain functionality in ultra-low-power modes but reduce bandwidth and increase conduction loss compared to +3V operation.
Is a bypass capacitor required for stable operation of the MAX4741EUA+TGA5?
Yes, a 0.1µF ceramic capacitor from V+ to GND is recommended and sufficient for most applications. This minimizes supply noise coupling, improves noise margin during fast switching transitions, and stabilizes internal bias networks-especially critical when driving capacitive loads or sharing V+ with other high-speed ICs.
What is the function of Pin 4 (GND) in the MAX4741EUA+TGA5 µMAX package?
Pin 4 (GND) serves as the common analog and digital ground reference for the MAX4741EUA+TGA5. It establishes the return path for switch currents, defines logic threshold baselines, and anchors internal ESD protection structures. A low-impedance connection to system ground is mandatory to meet leakage (±5nA), crosstalk (-110dB), and THD (0.02%) specifications.
