Product details
Overview
MAX4736EUB+ from Maxim Integrated is a low-voltage, dual single-pole/double-throw (SPDT) analog switch operating from a single 1.6V to 4.2V supply. It delivers 0.6Ω on-resistance at 3V, 25ns turn-on time, break-before-make switching, and 1.8V CMOS logic compatibility-enabling rail-to-rail signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4736EUB+ datasheet, MAX4736EUB+ pinout, MAX4736EUB+ application, or MAX4736EUB+ equivalent, key selection criteria include on-resistance matching (0.1Ω max), off-isolation (-52dB at 1MHz), charge injection (60pC), thermal performance up to +85°C, and μMAX package footprint compatibility with space-constrained portable designs.
Technical Context
The MAX4736EUB+ uses CMOS switch architecture to support bidirectional, rail-to-rail analog signal handling from GND to V+. Its break-before-make timing (5ns typical) prevents momentary shorting during channel switching, critical for power routing and communications circuits where signal integrity must be preserved across transitions.
Each SPDT channel integrates independent digital control inputs (IN1/IN2) compatible with 1.8V logic levels at 3V supply, enabling direct interfacing with low-voltage microcontrollers. The device maintains tight RON flatness (0.05Ω typical) over its full analog signal range, ensuring minimal distortion in audio and video signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 4.2V single supply - enables operation directly from Li-ion or regulated 3.3V/1.8V rails without level-shifting. |
| On-Resistance (RON) | 0.6Ω typical at 3V - supports ≤300mA continuous current per channel with <100mV drop at full load. |
| RON Matching | 0.1Ω max between channels - ensures matched gain/attenuation in differential or dual-path signal routing. |
| Switching Speed | tON = 25ns, tOFF = 20ns max - suitable for high-speed multiplexing in data-acquisition and modem interfaces. |
| Off-Isolation | -52dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-signal systems. |
| Charge Injection | 60pC - limits voltage glitch on COM pins during switching, preserving accuracy in precision ADC front-ends. |
| Logic Compatibility | 1.8V CMOS input thresholds at 3V supply - allows direct drive from 1.8V I/O domains without external translators. |
Pinout & Package
MAX4736EUB+ is housed in a 10-pin μMAX package (3mm × 3mm, 0.8mm height), featuring an exposed pad thermally connected to GND. Pin 1 is IN1; pins 2 and 4 are NO1 and NO2; pins 9 and 7 are NC1 and NC2; pins 10 and 6 are COM1 and COM2; pin 3 is GND; pin 8 is V+; pins 5 and - are IN2 and N.C., respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Active-high logic signals selecting NO/NC path for each SPDT channel independently. |
| NO1, NO2 | Normally open analog terminals | Connected to COMx only when corresponding INx is high; isolated otherwise. |
| NC1, NC2 | Normally closed analog terminals | Connected to COMx only when corresponding INx is low; isolated otherwise. |
| COM1, COM2 | Common analog terminals | Bidirectional signal ports routing to either NOx or NCx based on INx state. |
| V+ | Positive supply input | Single power rail supporting full rail-to-rail analog swing; bypass capacitor required at pin. |
| GND | Ground reference | Return path for supply and analog signals; connects to exposed pad for thermal and noise control. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5ns minimum interval prevents signal shorting during channel transition in power routing. |
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to V+, eliminating clipping in audio and sensor interfaces. |
| Ultra-low quiescent power | <4μW typical - extends battery life in always-on cellular phone and modem applications. |
| Low RON flatness | 0.05Ω typical variation over full signal range - preserves linearity in precision instrumentation front-ends. |
| High off-isolation & low crosstalk | -52dB isolation and -78dB crosstalk at 1MHz - maintains signal separation in multi-channel video/audio switches. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4676EUB+ | Higher RON (1.2Ω at 3V), slower tON/tOFF (45ns/35ns), same μMAX package and 1.6V–4.2V supply. | Lower bandwidth (70MHz vs. 130MHz) and higher THD (0.03% vs. 0.018%) limit use in high-fidelity audio. | Select when cost sensitivity outweighs speed/linearity requirements; not recommended for precision data acquisition. |
| ADG732BRUZ | 32-channel single-pole/single-throw (SPST), 4.5Ω RON at 3V, 16-bit-compatible logic, TSSOP-48 package. | Higher channel count but larger footprint and higher on-resistance - unsuitable for space-constrained dual-SPDT layouts. | Choose only for multi-channel scanning needs; incompatible pinout and function prevent drop-in replacement. |
Compared with MAX4736EUB+, MAX4676EUB+ trades performance for cost in less demanding signal paths, while ADG732BRUZ offers scalability at the expense of size and RON - making MAX4736EUB+ optimal for compact, high-fidelity dual-SPDT routing where low distortion and fast settling are essential.

FAQ
What is the maximum continuous current rating for MAX4736EUB+ per channel?
The MAX4736EUB+ supports ±300mA continuous current through each COM, NO, or NC terminal. This rating holds across the full operating temperature range (-40°C to +85°C) and is validated under worst-case conditions including 3.6V supply and ambient temperatures up to +70°C. Exceeding this current may degrade RON stability or accelerate wear-out.
Does MAX4736EUB+ support rail-to-rail analog signal switching?
Yes, MAX4736EUB+ supports rail-to-rail analog signal switching from GND to V+ across its full specified supply range (1.6V to 4.2V). This capability is enabled by its CMOS process architecture and internal level-shifting design, allowing undistorted passage of signals such as audio waveforms or sensor outputs without clipping or compression.
What is the logic voltage compatibility of MAX4736EUB+ inputs at 3V supply?
At a 3V supply, MAX4736EUB+ digital inputs (IN1/IN2) are 1.8V CMOS compatible, with VIH = 1.4V min and VIL = 0.5V max. This allows direct interfacing with 1.8V microcontroller I/O without level shifters, while also tolerating input voltages up to 3.6V regardless of V+ - simplifying mixed-voltage system integration.
How does break-before-make timing function in MAX4736EUB+?
MAX4736EUB+ guarantees break-before-make operation with a minimum 5ns interval between disconnecting one path and connecting the other within each SPDT channel. This prevents momentary shorting between NO and NC terminals during switching - a critical feature for avoiding signal corruption in power routing and communications circuits where simultaneous conduction could cause latch-up or data errors.
What package type is used for MAX4736EUB+ and what are its thermal considerations?
MAX4736EUB+ uses a 10-pin μMAX package (3mm × 3mm) with an exposed pad that must be soldered to a PCB ground plane. Thermal resistance θJA is 5.6mW/°C above +70°C, yielding 444mW maximum continuous power dissipation at TA = +70°C. Proper grounding of the exposed pad is essential to maintain junction temperature below +150°C under full-load conditions.
