Product details
Overview
MAX4611CSD+T from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with normally closed (NC) configuration, 100Ω max on-resistance at +5V supply, 4Ω max channel-to-channel on-resistance match, and rail-to-rail analog signal handling from V+ to GND - used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4611CSD+T datasheet, MAX4611CSD+T pinout, MAX4611CSD+T application, or MAX4611CSD+T equivalent, key selection criteria include NC-switch topology, guaranteed 1nA off-leakage at +25°C, TTL/CMOS-compatible logic thresholds, and 14-pin narrow SO package compatibility with space-constrained portable instrumentation designs.
Technical Context
The MAX4611CSD+T implements four independent NC analog switches controlled by standard digital inputs, each supporting bidirectional signal flow across its COM–NC path with no polarity restriction. Its CMOS transmission-gate architecture ensures symmetrical on-resistance behavior and minimal charge injection (1–5pC).
It operates from a single +2V to +12V supply, with logic thresholds fixed at +0.8V (low) and +2.4V (high) for +5V operation - eliminating level-shifting needs in mixed-signal microcontroller interfaces. Signal bandwidth exceeds 300MHz, and off-isolation reaches –60dB at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 100Ω at +5V supply - ensures <1% gain error in 10kΩ impedance signal paths |
| On-Resistance Match | 4Ω max between channels - enables precision multiplexing without calibration |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance sample-and-hold nodes |
| Analog Signal Range | Rail-to-rail (GND to V+) - supports full-scale input without clamping diodes |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V) - direct interface with +5V microcontrollers |
| Turn-On/Off Time | 35ns / 15ns - suitable for 10MHz switching-rate applications |
| ESD Protection | >2kV per Method 3015.7 - robust handling during board assembly and field use |
Pinout & Package
MAX4611CSD+T is housed in a 14-pin narrow SO (Small Outline) package with exposed pad not present - footprint compatible with industry-standard SOIC-14 layouts and reflow soldering profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = LOW |
| 2, 4, 9, 10 | COM1–COM4 | Common analog I/O nodes - bidirectional signal path shared with NC pins |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - active-low logic controls NC switch state |
| 7 | GND | Digital/analog reference ground - must be tied to system ground plane |
| 14 | V+ | Single positive supply - powers analog core and logic interface (2V to 12V) |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed NC topology | Four dedicated normally closed switches - eliminates external pull-up/down components in fail-safe signal paths |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - enables direct interfacing with sensors and DACs without level shifting |
| Matched on-resistance | ≤4Ω difference between any two channels - critical for multi-channel instrumentation requiring channel-to-channel consistency |
| Low off-leakage current | ≤2nA at +85°C - maintains integrity of high-Z sample-and-hold capacitors over temperature |
| High off-isolation | –60dB at 1MHz - suppresses crosstalk between inactive channels in dense routing environments |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data Acquisition |
|---|---|
Use Scenario: Switching microphone or line-level audio signals between multiple codecs in handheld medical devices. IC Role / Device Role / Timing Role: Quad NC analog switch routing analog inputs to ADC front-end while maintaining signal fidelity and power-off safety. Use Value: Rail-to-rail operation preserves full dynamic range; 1nA leakage prevents DC offset drift in AC-coupled paths. |
Use Scenario: Multiplexing sensor outputs (thermocouples, strain gauges) into a single SAR ADC in portable test equipment. IC Role / Device Role / Timing Role: Precision analog multiplexer with matched RON ensuring consistent gain across channels. Use Value: 4Ω max RON mismatch minimizes channel-dependent gain error; low THD (<0.009%) preserves measurement linearity. |
| Sample-and-Hold Circuits | Communication Signal Switching |
Use Scenario: Controlling hold capacitor connection in precision sampling systems for oscilloscopes and digitizers. IC Role / Device Role / Timing Role: NC switch isolating hold capacitor during acquisition phase, then connecting it during hold phase. Use Value: Low charge injection (1–5pC) prevents voltage step errors on hold capacitors; fast tOFF (15ns) enables sub-100ns sampling windows. |
Use Scenario: Reconfiguring RF front-end signal paths (IF routing, filter bank selection) in software-defined radio modules. IC Role / Device Role / Timing Role: High-bandwidth analog switch enabling dynamic IF path reconfiguration under MCU control. Use Value: 300MHz on-channel bandwidth supports up to 100MHz IF signals; >2kV ESD protects against handling damage in field-deployable units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611CUD+ | Same electrical specs, TSSOP-14 package (3.1mm × 5.1mm vs SO-14's 3.9mm × 8.7mm) | Preferred for high-density PCBs where footprint area is constrained | Select when board layout requires smaller package and thermal performance permits |
| ADG1411BRZ | Quad NC switch, but higher on-resistance (1.8Ω typical), wider supply range (±15V dual or +3V to +40V single), no guaranteed 4Ω match | Suitable for industrial systems needing higher voltage tolerance, not precision-matched low-voltage routing | Choose only if operating above +12V or requiring bipolar supply capability |
Compared with MAX4611CSD+T, the MAX4611CUD+ offers identical performance in a smaller TSSOP package ideal for compact layouts, while the ADG1411BRZ trades matched RON and low-voltage optimization for extended voltage range - making MAX4611CSD+T the optimal choice for battery-powered, precision-multiplexed signal chains below +12V.

FAQ
What is the maximum supply voltage for MAX4611CSD+T?
The absolute maximum supply voltage (V+) for MAX4611CSD+T is +13V referenced to GND. Operation is specified from +2V to +12V; exceeding +13V risks permanent damage. At +12V, on-resistance drops to 30Ω (typ), improving drive capability in high-current analog paths - always bypass V+ with ≥0.1µF ceramic capacitor near the MAX4611CSD+T pins.
Does MAX4611CSD+T support bidirectional signal flow?
Yes, MAX4611CSD+T supports fully bidirectional analog signal flow between COM and NC terminals. Its CMOS transmission-gate structure imposes no directionality - signals pass equally well from COM to NC or NC to COM, enabling flexible routing in both source and load configurations within the MAX4611CSD+T's rail-to-rail voltage range.
What is the logic behavior of MAX4611CSD+T inputs?
MAX4611CSD+T inputs are active-low: when INx = LOW (≤0.8V), the corresponding NCx switch closes (conducts); when INx = HIGH (≥2.4V), NCx opens (high-impedance). This NC topology provides fail-safe closure during power-down or logic fault conditions - a key reliability feature confirmed in the MAX4611CSD+T truth table and pin description.
Can MAX4611CSD+T operate from a +3V supply?
Yes, MAX4611CSD+T is fully functional at +3V. At this supply, on-resistance increases to 175Ω (max), and turn-on time extends to 140ns (max), but all specifications including leakage (<2nA at +85°C) and rail-to-rail signal handling remain valid. The +3V operation makes MAX4611CSD+T suitable for modern ultra-low-power microcontroller interfaces and coin-cell–powered devices.
Is MAX4611CSD+T RoHS-compliant and lead-free?
Yes, MAX4611CSD+T is RoHS-compliant and lead-free, indicated by the "+" suffix in the part number per Maxim's ordering information. The device uses matte-tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), allowing unlimited floor life and standard reflow profiles - verified in the official MAX4611CSD+T package documentation.
