Product details
Overview
MAX4611CSD+ 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 RON 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.
For engineers reviewing the MAX4611CSD+ datasheet, MAX4611CSD+ pinout, MAX4611CSD+ application, or MAX4611CSD+ equivalent, key selection criteria include NC-switch topology, guaranteed RON flatness (≤18Ω), sub-2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and 14-pin narrow SO package thermal performance (640mW at +70°C).
Technical Context
The MAX4611CSD+ implements four independent NC analog switches controlled by active-low digital inputs (IN1–IN4), where logic LOW enables conduction between COMx and NCx terminals. Its CMOS architecture ensures symmetrical on-resistance across the full analog signal range (GND to V+) and minimal charge injection (1–5pC).
It features integrated ESD protection (>2kV per Method 3015.7), rail-to-rail signal capability without external level-shifting, and logic thresholds fixed at +0.8V (VIL) and +2.4V (VIH) for reliable operation with +5V TTL/CMOS drivers - no external biasing required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or industrial systems without level shifters. |
| On-Resistance (RON) | ≤100Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision sensor or audio paths. |
| RON Match | ≤4Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation or balanced signal switching. |
| Off-Leakage Current | ≤2nA at +85°C - preserves accuracy in high-impedance sample-and-hold or pH sensor interfaces. |
| Signal Range | GND to V+ - supports true rail-to-rail analog signals without clipping or distortion in unipolar systems. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V at +5V) - interoperates directly with microcontroller GPIOs and FPGA I/O banks. |
| Bandwidth | 300MHz on-channel - suitable for video, RF sampling, and fast data-acquisition multiplexing up to 100Msps. |
Pinout & Package
MAX4611CSD+ is housed in a 14-pin narrow SO (Small Outline) package with standard JEDEC MO-153 footprint, 1.27mm pitch, and 640mW power dissipation rating at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 | Normally closed analog terminals - conduct to COMx when INx = LOW; open when INx = HIGH. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - connect to signal source/load; each pairs with one NCx terminal. |
| 5, 6, 12, 13 | IN1–IN4 | Active-low digital control inputs - drive LOW to close corresponding NC switch; HIGH to open. |
| 7 | GND | Digital/analog reference ground - must be tied to system ground plane for noise immunity and leakage control. |
| 14 | V+ | Positive supply for analog and digital circuitry - bypass with ≥0.1µF ceramic capacitor near pin for stability at high V+. |
Key Features
| Feature | Design Value |
|---|---|
| No power-supply sequencing dependency | V+ may be applied after logic/analog signals if current-limited to ≤20mA - simplifies power-up in portable designs. |
| Rail-to-rail signal handling | Analog signals swing fully from GND to V+ without distortion or turn-off - eliminates need for external clamping or bias networks. |
| Guaranteed RON flatness | ≤18Ω variation over full signal range - maintains consistent gain/attenuation in audio and measurement applications. |
| ESD robustness | >2kV HBM per Method 3015.7 - withstands handling and board-level ESD events without latch-up or parameter shift. |
| Low charge injection | 1–5pC - minimizes voltage glitch on high-Z nodes (e.g., integrator inputs or ADC sample capacitors). |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data-Acquisition Front-End |
|---|---|
Use Scenario: Switching microphone or line-level audio signals between multiple codecs or amplifiers in handheld medical or test equipment. IC Role / Device Role / Timing Role: Quad NC analog switch enabling signal path selection under microcontroller control; timing-critical only during mute/unmute transitions. Use Value: ≤100Ω RON and ≤18Ω flatness preserve SNR and THD (<0.009% at 20kHz); rail-to-rail support avoids DC blocking caps in unipolar supplies. | Use Scenario: Multiplexing outputs from multiple sensors (thermocouples, RTDs, strain gauges) into a single precision ADC input. IC Role / Device Role / Timing Role: Low-leakage analog multiplexer providing channel isolation; RON matching ensures consistent gain calibration across channels. Use Value: ≤2nA off-leakage at +85°C prevents measurement drift in high-Z sensor bridges; 4Ω RON match reduces channel-to-channel gain error to <0.5%. |
| Sample-and-Hold Circuit Switching | Communication Signal Path Control |
Use Scenario: Isolating the hold capacitor from input sources during acquisition phase in precision SAR or sigma-delta ADC systems. IC Role / Device Role / Timing Role: NC switch placed between signal source and hold capacitor; opens on rising edge of sample clock to freeze voltage. Use Value: 1–5pC charge injection limits voltage step error on 10nF hold capacitors to <0.5mV; fast tOFF (15–28ns) enables sub-100ns hold setup. | Use Scenario: Selecting between primary and backup RF transceiver paths or antenna diversity inputs in IoT modems. IC Role / Device Role / Timing Role: High-bandwidth analog switch routing baseband or IF signals; operates in NC mode for default-path continuity. Use Value: 300MHz bandwidth supports LTE/5G sub-6GHz IF switching; >60dB off-isolation prevents crosstalk between active and standby paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612CSD+ | Two NO + two NC channels vs. four NC - different switch logic polarity per channel pair. | Requires dual-control logic for mixed-path routing; not drop-in for pure NC-only use cases. | Select only when both NO and NC functionality is needed in same design; otherwise MAX4611CSD+ provides simpler control. |
| ADG1412BRUZ | Quad SPST, but all NO configuration; higher RON (1.8Ω typ at +5V) but wider supply (±15V or +12V); no guaranteed RON match spec. | Not functionally equivalent due to NO-only topology; requires inverted logic drive for NC-equivalent behavior. | Choose for higher-voltage or lower-RON needs where NC logic is implemented externally; not a direct replacement. |
Compared with MAX4612CSD+, the MAX4611CSD+ offers dedicated NC-only operation with tighter RON matching (4Ω vs. unspecified) and lower leakage - ideal for fail-safe default-closed paths. Versus ADG1412BRUZ, it trades higher RON for guaranteed matching, lower cost, and native NC logic - better suited for battery-powered, precision-matched switching.

FAQ
What is the maximum supply voltage for MAX4611CSD+ and what happens if exceeded?
The absolute maximum V+ rating for MAX4611CSD+ is +13V referenced to GND. Exceeding this voltage risks permanent damage due to junction breakdown or oxide stress. At +12V operation, a minimum 0.1µF ceramic bypass capacitor must be placed adjacent to the V+ pin to suppress transients. The device is characterized up to +12V, where RON drops to ≤46Ω - making +12V optimal for lowest on-resistance in high-current paths.
Does MAX4611CSD+ require external pull-up or pull-down resistors on its INx pins?
No, MAX4611CSD+ does not require external biasing on IN1–IN4. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (+0.8V VIL, +2.4V VIH) when operated from a +5V supply, allowing direct connection to microcontroller GPIOs, FPGA outputs, or logic gates without pull resistors. Input current remains ±0.1µA across temperature, minimizing loading on driving circuits.
How does the normally closed (NC) topology of MAX4611CSD+ affect system safety in power-loss scenarios?
The NC configuration of MAX4611CSD+ ensures that all four analog paths remain conductive (COMx ↔ NCx) when INx is un-driven or held HIGH - providing inherent fail-safe continuity. In a power-loss event where V+ collapses or control logic resets, the switches default to closed state, maintaining signal integrity in critical monitoring or alarm paths. This contrasts with NO devices like MAX4610CSD+, which would open under the same conditions.
Can MAX4611CSD+ handle bipolar analog signals such as ±2.5V?
No, MAX4611CSD+ cannot handle true bipolar signals. Its analog signal range is strictly 0V to V+, meaning it only supports unipolar operation. Applying negative voltages to COMx, NCx, or NOx pins violates the absolute maximum rating of –0.3V and risks forward-biasing internal ESD diodes, causing excessive leakage or latch-up. For ±2.5V signals, a dual-supply switch like MAX301 or ADG1414 is required.
What is the thermal performance of the 14-pin narrow SO package used in MAX4611CSD+?
The MAX4611CSD+ in 14-pin narrow SO has a power dissipation limit of 640mW at +70°C ambient, with a thermal derating factor of 8.00mW/°C above that temperature. At +85°C ambient, usable power drops to 520mW. This package offers superior thermal resistance compared to TSSOP (6.3mW/°C) and DIP (10.00mW/°C), making it preferred for sustained operation in compact enclosures or stacked PCB layouts where airflow is limited.
