Product details
Overview
MAX4611EUD from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with four normally closed (NC) channels. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches channel on-resistance within 4Ω max, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition front-ends where leakage-critical switching is required.
For engineers reviewing the MAX4611EUD datasheet, MAX4611EUD pinout, MAX4611EUD application, or MAX4611EUD equivalent, this page provides verified electrical specifications, TSSOP-14 pin mapping, real-world use cases in signal routing and sample-and-hold systems, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX4611EUD implements four independent NC analog switches using CMOS transmission-gate architecture. Each switch features matched on-resistance (ΔRON ≤ 4Ω), flat on-resistance over signal range (≤18Ω variation), and guaranteed off-leakage <2nA at +85°C. Its TTL/CMOS-compatible logic inputs (VIN_H = 2.4V min, VIN_L = 0.8V max at +5V) enable direct interfacing with microcontrollers without level-shifting.
It supports rail-to-rail analog operation from GND to V+, handles ±2kV ESD per Method 3015.7, and exhibits 300MHz on-channel bandwidth with -60dB off-isolation and -80dB crosstalk at 1MHz. Charge injection is specified at 1–5pC, critical for precision sample-and-hold accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 100Ω max at +5V supply - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| On-resistance match | 4Ω max between channels - enables precise gain-matching in multi-channel instrumentation |
| Off-leakage current | 2nA max at +85°C - preserves integrity of high-impedance sensor nodes and hold capacitors |
| Analog signal range | GND to V+ - supports full-rail signal routing without clipping in single-supply systems |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - allows direct connection to standard digital controllers |
| Bandwidth | 300MHz on-channel - suitable for audio, video, and medium-speed data-acquisition signals |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handheld and field-deployable equipment |
Pinout & Package
MAX4611EUD is housed in a 14-pin TSSOP package (lead-free, RoHS-compliant) with exposed-pad thermal enhancement not present in this variant. Pin 7 is GND; pins 1, 3, 8, 11 are NC terminals; pins 2, 4, 9, 10 are COM1–COM4; pins 13, 5, 6, 12 are IN1–IN4; pin 14 is V+.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog switch terminals - conduct to COM when IN = LOW |
| 2, 4, 9, 10 | COM1–COM4 | Common analog node - connects to NC terminal when switch is ON (IN = LOW) |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - active-low logic controls NC switch state |
| 7 | GND | Digital and substrate ground reference - must be low-impedance for leakage and noise control |
| 14 | V+ | Single positive supply for analog and digital circuitry - powers internal CMOS gates and switch transistors |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates need for external biasing in single-supply designs |
| Guaranteed on-resistance flatness | ≤18Ω variation across full signal range - maintains consistent gain/attenuation in precision measurement paths |
| Low temperature drift | On-resistance stable across -40°C to +85°C - ensures repeatability in industrial environments |
| High off-isolation | -60dB at 1MHz - prevents signal coupling between inactive channels in dense routing applications |
| Minimal charge injection | 1–5pC - reduces voltage glitch on hold capacitors, improving ADC sampling accuracy |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|
|
Use Scenario: Selecting between multiple microphone inputs or line-level sources in a battery-powered mixer. IC Role / Device Role / Timing Role: Quad NC switch routes analog audio paths under microcontroller GPIO control; no timing constraints beyond settling time. Use Value: 100Ω RON and -80dB crosstalk preserve SNR and channel separation; 2nA leakage prevents DC offset drift in AC-coupled stages. |
Use Scenario: Multiplexing sensor outputs (thermocouples, strain gauges) into a shared ADC front-end. IC Role / Device Role / Timing Role: Low-leakage NC switch isolates high-Z sensors during non-sampling intervals; charge injection <5pC minimizes hold-step error. Use Value: Matched 4Ω ΔRON enables ratiometric measurements; rail-to-rail range accommodates unipolar/bipolar sensor excitation. |
| Sample-and-Hold Circuits | Communication Interface Switching |
|
Use Scenario: Capturing fast transient waveforms in test equipment using a precision hold capacitor. IC Role / Device Role / Timing Role: NC switch connects input to hold capacitor only during acquisition phase; tON/tOFF ≤65ns/28ns support kHz-rate sampling. Use Value: 1–5pC charge injection limits hold-step error to sub-mV levels; low 2nA leakage extends hold time beyond 100ms at room temperature. |
Use Scenario: Isolating RS-232 or USB PHY lines during hot-plug events or power sequencing in embedded gateways. IC Role / Device Role / Timing Role: NC configuration provides default-connect behavior; switch opens only during fault or standby - enhancing system safety. Use Value: >2kV ESD rating protects downstream PHY ICs; 300MHz bandwidth supports full-speed USB 1.1 signaling without distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612EUD+ | Two NO + two NC switches vs. four NC - different truth table and default state | Used where mixed switching polarity is needed (e.g., redundant path + isolation) | Select MAX4612EUD+ only if dual-mode (NO/NC) functionality is required; not a drop-in replacement |
| ADG1411BRUZ | 4-channel NC switch, 1.5Ω typical RON, +3V to +40V supply, but higher 12nA leakage at +85°C | Better for high-voltage industrial I/O; less suitable for ultra-low-leakage portable sensing | Choose ADG1411BRUZ when wider supply range or lower on-resistance outweighs leakage sensitivity |
Compared with MAX4611EUD, MAX4612EUD+ offers configurable switch polarity but requires redesign of control logic, while ADG1411BRUZ trades higher leakage for broader voltage capability and lower RON - making MAX4611EUD optimal for low-leakage, +5V-centric portable systems.

FAQ
What is the maximum supply voltage for MAX4611EUD?
The absolute maximum V+ rating for MAX4611EUD is +13V referenced to GND. Operation above +12V is possible but requires careful bypassing (≥0.1µF ceramic capacitor near V+ pin) and attention to supply tolerance - ±5% 12V supplies may exceed 13V during transients. The device is fully characterized up to +12V.
Does MAX4611EUD support bidirectional analog signal flow?
Yes, MAX4611EUD supports fully bidirectional analog signal flow. As a passive CMOS transmission-gate switch, it imposes no directionality - signals pass equally well from COM to NC or NC to COM, provided they remain within the GND-to-V+ range and stay within the 20mA continuous current limit.
What is the logic polarity of MAX4611EUD's control inputs?
MAX4611EUD uses active-low logic: when an INx pin is driven LOW (≤0.8V), the corresponding NC switch closes (conducts between NCx and COMx); when INx is HIGH (≥2.4V), the switch opens. This default-closed behavior is intrinsic to its NC architecture and differs from NO variants like MAX4610EUD.
Can MAX4611EUD operate from a +3V supply?
Yes, MAX4611EUD operates from +2V to +12V. At +3V, on-resistance increases to 360Ω max (vs. 100Ω at +5V), and logic thresholds shift to VIN_H ≥ 1.0V / VIN_L ≤ 0.5V. THD rises slightly, but rail-to-rail signal handling and <2nA leakage at +85°C remain guaranteed - making it viable for ultra-low-power designs.
Is thermal pad connection required for MAX4611EUD?
No. The MAX4611EUD variant uses a 14-pin TSSOP package without an exposed thermal pad (EP). Exposed pads are only present in the QFN variants (e.g., MAX4611EGE+). Standard TSSOP mounting - with soldered leads and adequate PCB copper area under the body - provides sufficient thermal dissipation for typical loads (<500mW).
