Product details
Overview
MAX4752EGE+ from Maxim Integrated is a quad single-pole/single-throw (SPST) analog switch with four normally closed (NC) channels, operating from a single +1.6V to +3.6V supply. It delivers 0.9Ω maximum on-resistance at +3V, 30ns turn-on time, and 100mA continuous current handling - enabling precise low-voltage signal routing in battery-powered portable electronics.
For engineers reviewing the MAX4752EGE+ datasheet, MAX4752EGE+ pinout, MAX4752EGE+ application, or MAX4752EGE+ equivalent, this page provides verified electrical parameters, QFN-EP package details, NC-switching behavior, rail-to-rail analog support, and real-world use cases in audio routing and data-acquisition systems.
Technical Context
The MAX4752EGE+ implements CMOS-based SPST switching architecture with fully bidirectional analog paths between COM and NC terminals. Its logic inputs are 1.8V CMOS-compatible at +3V supply and tolerate up to +3.6V regardless of V+, supporting mixed-voltage control interfaces.
All four switches exhibit matched on-resistance (≤0.12Ω max matching at +3V) and flat on-resistance (≤0.1Ω max flatness), ensuring consistent signal integrity across channels and voltage ranges. No break-before-make timing is implemented - unlike the MAX4753 - as the MAX4752EGE+ is strictly NC-type with simultaneous channel actuation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.9Ω max at +3V supply - enables <10mV drop at 10mA, critical for precision low-voltage sensor multiplexing. |
| On-Resistance Matching (∆RON) | 0.12Ω max at +3V - ensures ≤1.3% gain error across channels in multi-channel instrumentation front-ends. |
| Turn-On/Off Time | tON = 30ns, tOFF = 25ns (RL = 50Ω, CL = 35pF) - supports >10MHz digital signal routing without edge degradation. |
| Analog Signal Range | Rail-to-rail (GND to V+) - preserves full dynamic range of baseband audio and ADC/DAC interface signals. |
| Supply Voltage Range | +1.6V to +3.6V single supply - compatible with Li-ion, Li-poly, and coin-cell power domains without level-shifting. |
| Logic Input Compatibility | 1.8V CMOS-compatible at +3V supply; VIH = 1.4V min, VIL = 0.5V max - interoperable with modern low-voltage microcontrollers. |
| Leakage Current | ±5nA max (COM/NC off-state, TA = -40°C to +85°C) - prevents DC offset accumulation in high-impedance sensor paths. |
Pinout & Package
MAX4752EGE+ is housed in a 3mm × 3mm, 16-pin QFN-EP package with exposed pad (EP) requiring connection to GND for thermal and electrical performance. Pin 1 is marked by a dot; EP must be soldered to a PCB thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 6, 7) | Ground reference | Primary return path for analog and digital currents; EP must connect here for optimal thermal dissipation and noise immunity. |
| V+ (Pin 14) | Positive supply input | Single bias rail for analog switch core and logic interface; requires 0.1µF bypass capacitor to GND near pin. |
| IN1–IN4 (Pins 12, 13, 4, 5) | Digital control inputs | Active-high logic: HIGH closes NC switch (connects COM to NC), LOW opens it; tolerant to 0–3.6V swing. |
| COM1–COM4 (Pins 2, 8, 9, 16) | Common analog terminals | Bidirectional signal ports - may serve as input or output depending on system topology and signal direction. |
| NC1–NC4 (Pins 15, 1, 11, 3) | Normally closed analog terminals | Connected to respective COM pins when INx = LOW; open when INx = HIGH - default-closed fail-safe path. |
Key Features
| Feature | Design Value |
|---|---|
| Low on-resistance flatness | 0.1Ω max variation over full 0–3V analog range - maintains amplitude consistency for audio and sensor signals. |
| High current capability | 100mA continuous per channel - supports direct driving of low-impedance loads like headphone amplifiers or ADC inputs. |
| Ultra-low quiescent power | <1µW at +3V - extends battery life in always-on monitoring circuits without compromising switching speed. |
| Charge injection control | 21pC typical - minimizes transient glitches during switching in sample-and-hold and multiplexer applications. |
| Off-isolation performance | -65dB at 1MHz - suppresses crosstalk between inactive channels in dense multi-signal routing boards. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4752EUD+ | Same electrical specs, but in 14-pin TSSOP package (5mm × 4.4mm) - larger footprint, no exposed pad. | Limited thermal performance in high-density layouts; suitable where QFN assembly is unavailable. | Select when board assembly process lacks QFN reflow capability or when manual prototyping favors TSSOP. |
| TMUX1574RTER | 0.5Ω max RON at 3.3V, 16-QFN, but NC/NO configurable per channel via register; higher supply current (1.5µA). | Requires I²C configuration; not pin-compatible; supports dynamic reconfiguration in field-upgradable systems. | Choose when programmable switch topology or lower RON justifies firmware integration and layout redesign. |
Compared with MAX4752EUD+, the MAX4752EGE+ offers superior thermal resistance (16.9W/°C derating vs. 9.1W/°C) and lower parasitic inductance due to QFN-EP construction - critical for high-frequency signal fidelity. Against TMUX1574RTER, it provides deterministic NC behavior without software overhead but lacks per-channel configurability.

FAQ
What is the default switch state of MAX4752EGE+ at power-up?
The MAX4752EGE+ features four normally closed (NC) switches, meaning each COM–NC path is conductive when all IN1–IN4 inputs are at logic LOW (e.g., during power-up before MCU initialization). This fail-safe behavior ensures default signal continuity without external pull-downs, reducing risk of silent audio or sensor dropout during boot.
Can MAX4752EGE+ operate with a 1.8V supply, and how does RON change?
Yes, MAX4752EGE+ operates from +1.6V to +3.6V. At +1.8V supply, its on-resistance increases to 2.5Ω max (vs. 0.9Ω at +3V), while maintaining 0.25Ω max matching. This remains suitable for low-bandwidth sensor routing but reduces usable current headroom - design verification at actual V+ is recommended for precision applications.
Is the exposed pad (EP) on MAX4752EGE+ electrically connected internally?
No, the exposed pad (EP) on MAX4752EGE+ is not internally connected to any die node. It must be externally soldered to a PCB ground plane to ensure thermal stability and EMI suppression. Leaving EP unconnected degrades thermal resistance by >30°C/W and increases susceptibility to switching noise coupling.
Does MAX4752EGE+ support bidirectional analog signal flow?
Yes, MAX4752EGE+ is fully bidirectional: COM and NC terminals may serve interchangeably as input or output. Signal polarity and direction are irrelevant to switching function - the device passes analog waveforms equally well in either direction, preserving phase and amplitude within RON and capacitance limits.
How does charge injection affect precision sampling when using MAX4752EGE+ in a multiplexer?
MAX4752EGE+ specifies 21pC typical charge injection, which - when switched into a 1nF hold capacitor - causes ~21mV transient step. For 12-bit accuracy (LSB = 1.2mV at 5V full-scale), this demands settling time or post-switch blanking. Using smaller hold capacitors or adding a reset switch mitigates residual error in high-resolution data acquisition.
