Product details
Overview
MAX4736EGC+ from Maxim Integrated is a low-voltage, dual SPDT analog switch operating from a single 1.6V to 4.2V supply, featuring 0.6Ω on-resistance (at 3V), 25ns turn-on time, break-before-make switching, and rail-to-rail analog signal handling-used in cellular phone power routing and audio signal path selection.
For engineers reviewing the MAX4736EGC+ datasheet, MAX4736EGC+ pinout, MAX4736EGC+ application, or MAX4736EGC+ equivalent, this page delivers verified electrical specs, package mapping to 12-pin TQFN (3mm × 3mm), thermal limits, leakage performance, and real-world design context for low-power portable systems.
Technical Context
The MAX4736EGC+ implements CMOS-based dual SPDT switching with independent IN1/IN2 digital control inputs, each driving one NO/NC/COM channel pair. Its break-before-make timing (5ns typical) prevents momentary shorting during state transitions, critical for battery-powered system power sequencing.
It supports bidirectional analog signal routing from GND to V+, with guaranteed RON flatness ≤0.05Ω (3V) and matching ≤0.1Ω across channels-enabling precision signal paths in data-acquisition front-ends and audio codecs where gain/phase consistency matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 4.2V single supply - enables direct integration with Li-ion battery (3.0–3.7V) and 1.8V logic domains without level shifters. |
| On-Resistance (RON) | 0.6Ω max at V+ = 3V - minimizes voltage drop and power loss in high-current (±300mA) power routing applications. |
| RON Matching | ≤0.1Ω between channels - ensures matched gain and signal integrity when routing differential or parallel analog paths. |
| Switching Speed | tON = 25ns, tOFF = 20ns - supports fast multiplexing in multi-channel ADC/DAC interfaces and burst-mode communications. |
| Logic Compatibility | 1.8V CMOS input threshold at 3V supply - allows direct interfacing with 1.8V microcontrollers without external translators. |
| Off-Isolation | −52dB at 1MHz - suppresses crosstalk between active and inactive signal paths in audio/video routing. |
| Charge Injection | 60pC - limits voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors), preserving ADC accuracy. |
Pinout & Package
MAX4736EGC+ is packaged in a 12-pin TQFN (3mm × 3mm) with exposed pad, requiring connection of the EP pin to GND for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Switch 1 | Active-high logic input controlling NO1/NC1 path selection; compatible with 1.8V CMOS at 3V V+. |
| 2 (COM1) | Common terminal for Switch 1 | Bidirectional analog node connecting to either NO1 or NC1; rated for ±300mA continuous current. |
| 3 (N.C.) | No connection | Unused internal bond pad; must be left floating or tied to GND per layout best practice. |
| 4 (NC1) | Normally closed terminal for Switch 1 | Analog path connected to COM1 when IN1 = low; clamped by internal diodes beyond V+ or GND. |
| 5 (V+) | Positive supply input | Single power rail (1.6–4.2V); bypass capacitor (0.1μF to GND) recommended adjacent to pin. |
| 6 (NC2) | Normally closed terminal for Switch 2 | Independent analog path for second SPDT; electrically isolated from Switch 1 except via shared V+/GND. |
| 7 (COM2) | Common terminal for Switch 2 | Second bidirectional analog node; identical current rating and signal range as COM1. |
| 8 (IN2) | Digital control input for Switch 2 | Independent logic input mirroring IN1 functionality; no cross-talk or timing dependency with IN1. |
| 9 (NO2) | Normally open terminal for Switch 2 | Open-circuit path until IN2 = high; exhibits same RON, flatness, and leakage as NO1. |
| 10 (GND) | Ground reference | Primary return path for supply and analog signals; connects to exposed pad (EP) for thermal conduction. |
| 11 (NO1) | Normally open terminal for Switch 1 | Activated when IN1 = high; maintains <0.05Ω RON flatness over full 0–V+ signal swing. |
| EP | Exposed thermal pad | Must be soldered to solid GND plane; improves thermal resistance by >30% and reduces junction temperature rise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output signals from GND to V+ without distortion or clipping-essential for full-scale battery voltage monitoring. |
| Break-before-make switching | Guaranteed 5ns minimum dead time prevents shoot-through in power domain isolation and battery switchover circuits. |
| Ultra-low quiescent power | <4μW typical supply current - extends runtime in always-on sensor hubs and standby audio subsystems. |
| Low charge injection (60pC) | Minimizes voltage step on high-Z sampling nodes, enabling use in precision 12-bit+ SAR ADC front-ends without calibration. |
| 1.8V CMOS logic compatibility | Accepts VIH ≥1.4V and VIL ≤0.5V at 3V V+, allowing direct interface with low-voltage FPGAs and application processors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574RTER | Higher RON (1.2Ω @3V), no break-before-make guarantee, 1.2V–5.5V supply range | Better suited for general-purpose I/O expansion than precision power routing due to higher on-resistance mismatch | Select when wider supply range and lower cost outweigh need for sub-0.1Ω RON matching and guaranteed BBM timing. |
| ADG736BRMZ-REEL | Similar RON (0.8Ω @3V), but only 1.8V–5.5V supply and no 1.6V operation; −40°C to +125°C rating | Preferred for automotive or industrial environments requiring extended temperature operation | Choose for AEC-Q100-compliant designs where extended temp range and ADI's qualification process are mandatory. |
Compared with TMUX1574RTER and ADG736BRMZ-REEL, the MAX4736EGC+ uniquely combines 1.6V minimum supply, 0.6Ω RON, guaranteed break-before-make, and 0.1Ω matching-making it optimal for space-constrained, battery-sensitive portable electronics where signal integrity and power efficiency are co-prioritized.

FAQ
What is the maximum continuous current rating for the MAX4736EGC+ analog switches?
The MAX4736EGC+ supports ±300mA continuous current through its COM_, NO_, and NC_ terminals. This rating applies across the full operating temperature range (−40°C to +85°C) and is validated for both 1.8V and 3V supply conditions. Exceeding this limit risks thermal overstress and parametric shift; peak pulsed current up to ±500mA is allowed at 1ms/10% duty cycle.
Does the MAX4736EGC+ support true rail-to-rail analog signal operation?
Yes, the MAX4736EGC+ supports analog signals from GND to V+ (e.g., 0V to 3.0V) on all COM_, NO_, and NC_ pins. Its CMOS architecture ensures minimal RON variation (<0.05Ω flatness) across this full range, enabling accurate signal transmission without clipping or distortion-critical for battery voltage monitoring and audio line-level routing.
What is the purpose of the exposed pad (EP) on the MAX4736EGC+ TQFN package?
The exposed pad (EP) on the MAX4736EGC+ serves as a thermal and electrical ground connection. It must be soldered to a solid GND plane to reduce thermal resistance by >30%, improve power dissipation capability (1176mW at +70°C), and stabilize analog performance. Leaving EP unconnected degrades thermal margin and may increase RON drift under load.
Can the MAX4736EGC+ operate reliably from a 1.6V supply?
Yes, the MAX4736EGC+ is fully specified down to 1.6V supply voltage. At 1.6V, it maintains functional switching with RON ≤3Ω (1.8V supply spec used as proxy), tON/tOFF ≤35ns, and logic compatibility (VIH ≤1.0V). This enables direct use with partially discharged Li-ion cells or energy-harvesting power sources in ultra-low-power IoT endpoints.
How does the break-before-make feature of the MAX4736EGC+ benefit power routing applications?
The MAX4736EGC+ guarantees a minimum 5ns break-before-make interval, preventing momentary short-circuiting between two power domains (e.g., main battery and backup battery). This eliminates shoot-through current, avoids supply contention, and protects downstream regulators-making it essential for safe, reliable power path management in portable electronics.
