Product details
Overview
MAX4575ESA from Maxim Integrated is a dual normally open (NO) single-pole/single-throw (SPST) CMOS analog switch, designed for rail-to-rail signal routing in low-voltage systems. It operates from +2V to +12V single supply, delivers 70Ω max on-resistance at +5V, guarantees 0.5nA off-leakage at +25°C, and withstands ±15kV ESD (HBM/IEC air-gap) on NO/NC pins-enabling robust audio switching and relay replacement in battery-powered test equipment.
For engineers reviewing the MAX4575ESA datasheet, MAX4575ESA pinout, MAX4575ESA application, or MAX4575ESA equivalent, key selection criteria include its dual NO topology, SO-8 package compatibility, guaranteed on-resistance flatness (2Ω typ), TTL/CMOS logic interface, and -3dB bandwidth exceeding 300MHz for high-fidelity signal integrity.
Technical Context
The MAX4575ESA implements two independent, bidirectional SPST switches with CMOS transmission-gate architecture, each controlled by dedicated TTL/CMOS-compatible digital inputs (IN1, IN2). Its internal SCR-based ESD protection activates within nanoseconds when NO/NC pins exceed supply rails, clamping ±15kV transients without latchup.
Signal handling is rail-to-rail across the full +2V to +12V supply range, with on-resistance matching of 0.5Ω (typ) between channels and flatness of 2Ω (typ) over the analog input range-critical for low-distortion (<0.015% THD) audio and precision data-acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply-supports direct integration into 3.3V and 5V battery-powered systems without level-shifting. |
| On-Resistance (max) | 70Ω at +5V-ensures minimal voltage drop and power loss in signal paths carrying up to ±10mA continuous current. |
| Off-Leakage Current | 0.5nA at +25°C-preserves accuracy in high-impedance sample-and-hold and sensor front-end circuits. |
| -3dB Bandwidth | >300MHz-enables clean switching of video, RF control, and fast digital signals without attenuation. |
| ESD Protection | ±15kV HBM and IEC 1000-4-2 air-gap on NO/NC pins-eliminates need for external TVS diodes in handheld or industrial I/O interfaces. |
| THD + Noise | 0.015% at 20Hz–20kHz-meets fidelity requirements for professional audio routing and studio-grade signal conditioning. |
| Turn-On/Off Time | 90ns/50ns typical at +5V-supports high-speed multiplexing in automated test equipment with sub-100ns channel settling. |
Pinout & Package
MAX4575ESA is housed in an 8-pin SO (SOIC) package (0.150" wide), RoHS-compliant with lead-free option available. Pin layout follows industry-standard SO-8 footprint, enabling drop-in compatibility with existing PCB layouts using similar analog switches.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO1 | Normally open terminal of Switch 1-connects to COM1 only when IN1 = logic high; isolated otherwise. |
| 2 | COM1 | Common terminal of Switch 1-carries bidirectional analog signal between NO1 and internal switch path. |
| 3 | IN2 | Digital control input for Switch 2-TTL/CMOS compatible; drives internal gate to close NO2–COM2 path. |
| 4 | GND | Analog and digital ground reference-must be low-impedance connection to minimize noise coupling into analog paths. |
| 5 | NO2 | Normally open terminal of Switch 2-connects to COM2 only when IN2 = logic high; provides second independent routing path. |
| 6 | COM2 | Common terminal of Switch 2-serves as shared signal node for Switch 2's bidirectional conduction path. |
| 7 | IN1 | Digital control input for Switch 1-accepts 0.8V/2.4V logic thresholds; enables precise timing-controlled switching. |
| 8 | V+ | Positive supply input-powers internal logic and switch circuitry; requires local 0.1µF bypass capacitor for ESD transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NO topology | Two independent normally open switches-ideal for enabling signal paths on demand while maintaining default isolation. |
| Rail-to-rail analog range | Full signal swing from GND to V+-preserves dynamic range in low-voltage audio and sensor interfaces without clipping. |
| On-resistance matching | 0.5Ω typical between channels-minimizes gain error and crosstalk in differential or parallel-switched configurations. |
| Charge injection | 4pC typical-reduces glitch-induced errors in sample-and-hold and switched-capacitor circuits. |
| Break-before-make timing | Not applicable-MAX4575ESA has NO-only configuration; break-before-make is exclusive to MAX4577 (NO+NC). |
Applications
| Audio Signal Routing | Automated Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4541ESA | Pin-compatible but NC-only dual switch; same SO-8 package and ESD rating; 150Ω max RON at +3V. | Used where default-closed signal paths are required (e.g., fail-safe sensor monitoring). | Select MAX4541ESA only if NC functionality is mandatory; MAX4575ESA offers lower RON and better matching for NO-dominant routing. |
| ADG1419BRMZ | Single-supply +5V–±15V operation; 0.6Ω RON matching; higher 1.8nA leakage; no integrated ±15kV ESD protection. | Suitable for precision instrumentation requiring ultra-low RON flatness but mandates external ESD components. | Choose ADG1419BRMZ for sub-1Ω matching needs; MAX4575ESA provides integrated ESD robustness and broader supply flexibility. |
Compared with MAX4541ESA and ADG1419BRMZ, the MAX4575ESA uniquely combines dual NO topology, ±15kV on-chip ESD protection, and 70Ω max on-resistance in SO-8-making it optimal for cost-sensitive, space-constrained, and field-deployed systems requiring zero external protection.

FAQ
What is the maximum supply voltage the MAX4575ESA can tolerate?
The MAX4575ESA supports a continuous single-supply range of +2V to +12V, with an absolute maximum rating of +13V on V+. Operation near +12V requires a minimum 0.1µF bypass capacitor from V+ to GND, placed as close as possible to the IC, to ensure stability during ESD events and high-current transients.
Does the MAX4575ESA support rail-to-rail analog signal switching?
Yes, the MAX4575ESA fully supports rail-to-rail analog signal switching-its CMOS transmission-gate design allows input signals from GND to V+ without clipping or distortion. This capability is confirmed across the entire specified temperature range (-40°C to +85°C) and supply voltages (+2V to +12V).
How does the ESD protection on the MAX4575ESA work, and what standards does it meet?
The MAX4575ESA integrates on-chip bidirectional SCRs on NO/NC pins, providing ±15kV protection per Human Body Model (HBM) and IEC 1000-4-2 air-gap discharge, plus ±8kV per IEC 1000-4-2 contact discharge. During an ESD event, the SCR triggers in nanoseconds and safely shunts current to GND-no external components needed for Level 4 system compliance.
Can the MAX4575ESA be used in audio applications, and what performance metrics support this?
Yes, the MAX4575ESA is explicitly qualified for low-distortion audio applications. Its 0.015% THD+N at 20Hz–20kHz, >300MHz -3dB bandwidth, and 20pF NO/NC off-capacitance ensure minimal signal degradation, phase shift, or crosstalk-validated in audio routing, mixer, and headphone amplifier enable-path designs.
What is the function of Pin 1 and Pin 5 on the MAX4575ESA?
Pin 1 is NO1 (Normally Open terminal of Switch 1), and Pin 5 is NO2 (Normally Open terminal of Switch 2). Both remain electrically isolated from their respective COM pins (Pins 2 and 6) until their corresponding control inputs (IN1 on Pin 7 and IN2 on Pin 3) are driven high-enabling precise, independent activation of two signal paths in the MAX4575ESA.
