Product details
Overview
MAX4611ESD+T from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with normally closed (NC) configuration, 14-pin narrow SO package, 100Ω max on-resistance at +5V supply, <2nA off-leakage at +85°C, and rail-to-rail analog signal handling (GND to V+). It enables precision signal routing in battery-powered instrumentation and low-voltage data-acquisition systems.
For engineers reviewing the MAX4611ESD+T datasheet, MAX4611ESD+T pinout, MAX4611ESD+T application, or MAX4611ESD+T equivalent, key selection criteria include NC-switch topology, guaranteed channel matching (≤4Ω), flat on-resistance over signal range, TTL/CMOS logic compatibility at +5V, and automotive-grade temperature support (–40°C to +85°C).
Technical Context
The MAX4611ESD+T implements four independent NC analog switches controlled by active-high digital inputs. Each switch conducts when its INx input is logic high (≥2.4V at +5V supply), connecting NCx to COMx with matched on-resistance and minimal charge injection (1–5pC).
It operates from a single +2V to +12V supply, supports rail-to-rail analog signals (V+ to GND), and features internal ESD protection (>2kV per Method 3015.7). Logic thresholds are fixed at +0.8V (low) and +2.4V (high), ensuring interoperability with standard TTL/CMOS drivers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four switches default closed; open only when INx = logic high |
| On-Resistance (max) | 100Ω at +5V supply - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| On-Resistance Match | ≤4Ω between channels - critical for multi-channel signal multiplexing where gain/offset tracking matters |
| Off-Leakage Current | <2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor front-end circuits |
| Analog Signal Range | Rail-to-rail (GND to V+) - supports full-supply-range signal switching without clipping or distortion |
| Logic Compatibility | TTL/CMOS at +5V - direct interface with microcontrollers, FPGAs, and logic families without external biasing |
| ESD Protection | >2kV per Method 3015.7 - enhances robustness in handling-sensitive industrial and portable equipment |
Pinout & Package
MAX4611ESD+T is housed in a 14-pin narrow SO (small outline) package with standard JEDEC MS-012AC footprint. Pin 7 is GND; pin 14 is V+; pins 1, 3, 8, 11 are NC1–NC4; pins 2, 4, 9, 10 are COM1–COM4; pins 13, 5, 6, 12 are IN1–IN4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 (Normally Closed) | Analog output terminals that connect to COMx when corresponding INx = logic high; floating when off |
| 2, 4, 9, 10 | COM1–COM4 (Common) | Analog input/common nodes - each pairs with one NCx terminal to form an NC switch path |
| 13, 5, 6, 12 | IN1–IN4 (Digital Control) | Active-high logic inputs - high voltage (≥2.4V) opens the associated NC switch; low voltage (≤0.8V) closes it |
| 7 | GND | Digital and substrate ground reference - must be connected to system ground plane for stable switching |
| 14 | V+ | Single positive supply for analog and digital circuitry - powers internal CMOS switches and logic; bypass with 0.1µF near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clamping - eliminates need for external level-shifting in ±5V or single-supply systems |
| Guaranteed on-resistance flatness | ≤18Ω max variation across full signal range - maintains consistent gain and linearity in audio and measurement applications |
| Low charge injection | 1–5pC - minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold capacitors), reducing settling error |
| Automotive temperature grade | –40°C to +85°C operating range - qualified for under-hood and industrial control environments requiring extended thermal reliability |
| High off-isolation | –60dB at 1MHz - suppresses crosstalk between inactive channels in multi-signal routing (e.g., A/V matrix switches) |
Applications
| Audio Signal Routing | Portable Data Acquisition |
|---|---|
Use Scenario: Switching between multiple microphone inputs or headphone outputs in a handheld audio recorder. IC Role / Device Role / Timing Role: Quad NC analog switch providing low-distortion, low-noise signal path selection with no DC bias requirements. Use Value: Rail-to-rail operation preserves full dynamic range; <2nA leakage prevents DC offset drift in high-Z mic preamp stages. |
Use Scenario: Multiplexing sensor outputs (thermocouples, RTDs) into a shared ADC in a battery-powered environmental monitor. IC Role / Device Role / Timing Role: Precision analog switch enabling sequential sampling of up to four sensors while maintaining signal integrity. Use Value: ≤4Ω channel matching ensures consistent gain scaling; 100Ω on-resistance introduces negligible loading on high-output-impedance sensors. |
| Sample-and-Hold Circuits | Communication Interface Protection |
Use Scenario: Controlling hold capacitor charging in a precision ADC front-end where timing jitter and charge kickback must be minimized. IC Role / Device Role / Timing Role: Low-charge-injection NC switch isolating the hold capacitor during acquisition phase. Use Value: 1–5pC charge injection limits voltage step on 10nF hold capacitor to <0.5mV - reduces aperture uncertainty and improves ENOB. |
Use Scenario: Isolating RS-232 or CAN transceiver lines during power-down or fault conditions in automotive telematics modules. IC Role / Device Role / Timing Role: Fail-safe analog switch that defaults closed (NC) to maintain signal continuity unless actively opened by control logic. Use Value: –40°C to +85°C rating ensures reliability across vehicle thermal cycles; >2kV ESD protects against connector hot-plug transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611EUD+ | Same electrical specs and NC function, but in 14-pin TSSOP package (3.1mm × 5mm vs. SO's 3.9mm × 8.7mm) | Preferred for space-constrained PCB layouts; requires rework of land pattern and stencil | Select when board area is limited and thermal dissipation <500mW suffices |
| ADG1412BRUZ | Quad SPST NC switch with lower on-resistance (1.8Ω typ), wider supply (±15V or +12V), but higher leakage (20nA @ +85°C) | Better for high-precision, wide-supply industrial systems; less suitable for ultra-low-leakage battery monitoring | Choose when sub-2Ω RON and bipolar operation outweigh leakage sensitivity |
Compared with MAX4611ESD+T, MAX4611EUD+ offers identical performance in a smaller footprint but reduced thermal margin, while ADG1412BRUZ delivers superior on-resistance and voltage range at the cost of higher off-leakage - making MAX4611ESD+T optimal for thermally stable, low-leakage, cost-sensitive industrial designs.

FAQ
What is the maximum supply voltage for MAX4611ESD+T?
The absolute maximum V+ rating for MAX4611ESD+T is +13V referenced to GND. Continuous operation is specified from +2V to +12V. Exceeding +13V risks permanent damage. At +12V, on-resistance drops to 30–60Ω (typ/max), and logic thresholds shift to VIN_H = 4.0V, VIN_L = 0.8V. Always bypass V+ with ≥0.1µF ceramic capacitor close to the pin.
Does MAX4611ESD+T support bidirectional signal flow?
Yes, MAX4611ESD+T supports fully bidirectional analog signal flow between NCx and COMx terminals. Its CMOS architecture imposes no inherent directionality - signal polarity and current direction are irrelevant as long as voltage stays within GND to V+. This enables use in both source and sink configurations, such as sensor excitation reversal or dual-path audio switching.
How does the NC configuration of MAX4611ESD+T affect system fail-safe behavior?
The NC configuration means MAX4611ESD+T defaults to conducting (closed) when INx = logic low or unpowered. This provides inherent fail-safe continuity - e.g., maintaining audio path or sensor connection during MCU reset or power loss. To break the path, drive INx high. This behavior contrasts with NO variants like MAX4610ESD+T and is critical in safety-critical routing where signal loss must be actively commanded.
Can MAX4611ESD+T operate from a +3V supply?
Yes, MAX4611ESD+T is fully functional at +3V. At this supply, on-resistance increases to 175–450Ω (max), off-leakage remains <2nA at +85°C, and logic thresholds adjust to VIN_H = 2.4V (min), VIN_L = 0.5V (max). THD rises slightly (<0.01% at 1kHz), and bandwidth decreases - but it remains suitable for low-speed sensor multiplexing and battery-monitoring applications where power efficiency is prioritized.
Is thermal performance affected by the narrow SO package of MAX4611ESD+T?
Yes - the 14-pin narrow SO package (MAX4611ESD+T) has a thermal resistance θJA of 125°C/W (typ), limiting continuous power dissipation to 640mW at +70°C ambient (derated 8mW/°C above). For high-channel-count or high-current operation (>5mA per switch), ensure adequate copper pour on the GND pad and avoid stacking heat-generating components nearby. The QFN variant (MAX4611EGE+) offers lower θJA (≈45°C/W) but requires different layout.
