Product details
Overview
MAX4575EUA+ from Maxim Integrated is a dual normally open (NO) SPST CMOS analog switch with ±15kV ESD protection on NO/NC pins, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - designed for low-distortion audio routing and relay replacement in battery-powered test equipment.
For engineers reviewing the MAX4575EUA+ datasheet, MAX4575EUA+ pinout, MAX4575EUA+ application, or MAX4575EUA+ equivalent, this page delivers verified electrical specs, µMAX-8 package details, ESD robustness context, and real-world switching performance metrics for precision analog signal path design.
Technical Context
The MAX4575EUA+ implements dual independent SPST switches with TTL/CMOS-compatible digital control inputs (IN1, IN2), each driving a normally open analog path between COM and NO terminals. Its CMOS architecture enables rail-to-rail analog signal operation from +2V to +12V single supply while maintaining sub-nA leakage and <2Ω on-resistance flatness at +5V.
ESD protection is implemented via on-chip bidirectional SCRs on NO/NC pins, rated for ±15kV (IEC 1000-4-2 air-gap), with 110mA holding current and 3V holding voltage - requiring external current limiting below 35mA at +85°C to ensure automatic SCR turn-off after discharge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths |
| Off-Leakage Current | 0.5nA at +25°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces |
| ESD Protection | ±15kV HBM & IEC 1000-4-2 air-gap - eliminates need for external TVS diodes on NO/NC lines |
| -3dB Bandwidth | >300MHz - supports video, high-speed data acquisition, and broadband communication signals |
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery systems |
| THD | 0.015% - meets fidelity requirements for professional audio switching without audible artifacts |
| Turn-On/Off Time | 90ns/50ns typical at +5V - supports fast multiplexing in automated test and data logging |
Pinout & Package
MAX4575EUA+ is housed in an 8-pin µMAX package (3mm × 3mm, 0.8mm height, exposed pad), optimized for space-constrained portable and instrumentation designs. Pin pitch is 0.65mm; thermal resistance θJA = 243°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO1 | Analog Switch 1 Normally Open terminal | Connects to COM1 when IN1 = logic high; isolated at logic low; ±15kV ESD protected |
| 2 - COM1 | Analog Switch 1 Common terminal | Signal input/output node shared with NO1/NC1; rail-to-rail capable; 12pF off-capacitance |
| 3 - IN2 | Digital Control Input 2 | TTL/CMOS-compatible (VIH = 2.4V, VIL = 0.8V); controls NO2/COM2 path independently |
| 4 - GND | Ground reference | Return path for supply and signal; must be low-impedance for ESD current shunting |
| 5 - NO2 | Analog Switch 2 Normally Open terminal | Connects to COM2 when IN2 = logic high; identical ESD and RON specs as NO1 |
| 6 - COM2 | Analog Switch 2 Common terminal | Independent signal path from COM1; matched RON (0.5Ω typ) enables balanced channel routing |
| 7 - IN1 | Digital Control Input 1 | Directly controls NO1/COM1; no internal pull-up/down; requires clean logic drive |
| 8 - V+ | Positive supply input | Accepts +2V to +12V; bypass with 0.1µF ceramic capacitor close to pin for ESD stability |
Key Features
| Feature | Design Value |
|---|---|
| ±15kV ESD protection on NO/NC pins | Eliminates external protection components and passes IEC 61000-4-2 Level 4 without derating |
| On-resistance matching | 0.5Ω typical between channels at +5V - enables precise differential or ratiometric signal routing |
| Rail-to-rail analog signal range | Supports full-supply-swing signals (e.g., 0–5V, 0–3.3V) without clipping or distortion |
| Low charge injection (4pC) | Minimizes voltage glitch in sample-and-hold and switched-capacitor circuits |
| Bilateral signal flow | Allows signal routing in either direction - essential for bidirectional sensor or audio interface paths |

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 |
|---|---|---|---|
| MAX4541EUA+ | Same pinout, but single-channel NO switch; 100Ω RON max at +5V; no ESD rating specified | Limited to single-path routing; unsuitable for ESD-prone front-panel interfaces | Select only if dual-channel functionality is unnecessary and board layout allows rework to single switch per path |
| ADG1419BRMZ | Single-supply +5V to +16.5V; 0.6Ω RON matching; ±20kV ESD; 10-lead MSOP package | Higher voltage capability and tighter matching, but larger footprint and non-pin-compatible | Prefer for industrial systems needing >12V operation or sub-ohm matching, accepting PCB redesign |
Compared with MAX4541EUA+ and ADG1419BRMZ, the MAX4575EUA+ uniquely balances dual NO topology, µMAX-8 compactness, guaranteed ±15kV ESD, and 70Ω RON in a production-ready, drop-in solution for portable and test equipment where space, reliability, and audio-grade linearity are co-prioritized.

FAQ
What is the maximum supply voltage for MAX4575EUA+?
The MAX4575EUA+ operates from a single supply of +2V to +12V. Its absolute maximum rating is +13V referenced to GND. For reliable operation near +12V, a 0.1µF ceramic bypass capacitor must be placed directly between V+ and GND, as specified in the datasheet to stabilize ESD response and prevent supply rail coupling.
Does MAX4575EUA+ support rail-to-rail analog signals?
Yes, MAX4575EUA+ fully supports rail-to-rail analog signal operation - meaning signals from 0V to V+ (e.g., 0–5V or 0–3.3V) pass through the switch without clipping or distortion. This is enabled by its CMOS process and complementary transistor structure, confirmed in both the General Description and Electrical Characteristics sections of the datasheet.
How does the ±15kV ESD protection work on MAX4575EUA+?
MAX4575EUA+ uses on-chip bidirectional silicon-controlled rectifiers (SCRs) between NO/NC pins and GND to clamp ±15kV ESD transients (per IEC 1000-4-2 air-gap). During an event, the SCR latches on until current falls below its 110mA holding current - so external current limiting below 35mA at +85°C is required to guarantee automatic recovery.
Is MAX4575EUA+ pin-compatible with other devices in the MAX457x family?
Yes, MAX4575EUA+, MAX4576EUA+, and MAX4577EUA+ share identical 8-pin µMAX pinouts and logic interface behavior. The only functional difference is switch configuration: MAX4575EUA+ has two NO switches, MAX4576EUA+ has two NC, and MAX4577EUA+ has one NO + one NC - allowing direct substitution where topology matches.
What is the typical on-resistance matching between the two switches in MAX4575EUA+?
The typical on-resistance matching (∆RON) between the two NO switches in MAX4575EUA+ is 0.5Ω at +5V and +25°C, with a maximum of 3Ω over the full temperature range (-40°C to +85°C). This tight matching is critical for differential signal routing and ratiometric measurement accuracy in precision data acquisition systems.
