Product details
Overview
MAX4515ESA from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST), CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It operates from +2V to +12V single supply, delivers 10Ω on-resistance at +12V, guarantees ≤20nA off-leakage at +85°C, and supports TTL/CMOS logic compatibility with +5V supply - ideal for battery-powered audio switching and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4515ESA datasheet, MAX4515ESA pinout, MAX4515ESA application, or MAX4515ESA equivalent, this page provides verified pin assignments, real-world leakage and timing specs, confirmed SOT23-5 package mapping, and two validated alternative parts for NC SPST analog switch replacement in portable and industrial signal-path designs.
Technical Context
The MAX4515ESA implements a complementary CMOS transmission-gate architecture with internal level-shifting logic, enabling rail-to-rail analog signal handling across its full +2V to +12V supply range. Its digital control input accepts 0.8V–2.4V thresholds at +5V supply, ensuring direct interface with standard logic without external level translation.
It features break-before-make timing (tON = 150ns, tOFF = 100ns at +5V), 10pC charge injection, and ESD protection diodes clamping analog pins to V+ and GND - critical for maintaining signal integrity in high-impedance sensor or audio paths where leakage and transient errors must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - conducts when control input is LOW, blocks when HIGH. |
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 12V systems without dual-supply complexity. |
| On-Resistance | 10Ω max at +12V supply - ensures minimal insertion loss and voltage drop in precision signal paths. |
| Off-Leakage Current | ≤20nA at +85°C - preserves accuracy in high-impedance sensor or battery-monitoring circuits over temperature. |
| Charge Injection | 10pC max - limits voltage glitch on switched capacitive loads (e.g., ADC sample capacitors) to <1mV with 10nF load. |
| Switching Speed | tON = 150ns, tOFF = 100ns at +5V - supports multiplexing of audio-band and medium-speed data signals. |
| Logic Compatibility | 0.8V–2.4V input thresholds at +5V - interoperates directly with 5V TTL and CMOS outputs without pull-ups or translators. |
Pinout & Package
SOT23-5 surface-mount package (3.0mm × 1.75mm footprint, 1.3mm height), rated for -40°C to +85°C operation, with exposed pad not internally connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No connection | Not internally bonded - must be left floating or grounded per layout best practice; no electrical function. |
| 2 - IN | Digital control input | Active-low logic: LOW = switch ON (NC path closed); HIGH = switch OFF (NC path open). |
| 3 - GND | Analog/digital ground reference | Common return for V+, analog signals, and logic - requires low-impedance PCB plane for leakage and noise control. |
| 4 - V+ | Positive supply rail | Powers analog switches and internal logic; also ties substrate - must be decoupled within 1cm of pin. |
| 5 - COM | Common analog terminal | Center node of NC switch; bidirectional - connects to NC terminal when IN = LOW. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to V+ - eliminates level-shifting needs in mixed-supply systems. |
| Guaranteed low on-resistance flatness | ΔRON ≤ 3Ω over full signal range at +5V - maintains consistent gain and linearity across audio and sensor signals. |
| Break-before-make timing | tON > tOFF at +5V - prevents momentary shorting between channels in multi-switch configurations. |
| Low charge injection (10pC) | Minimizes settling error in sample-and-hold or switched-capacitor circuits - critical for 12-bit+ ADC front-ends. |
| ESD-protected analog terminals | Internal diodes clamp NO/NC/COM to V+ and GND - withstands >2000V HBM without external protection components. |
Applications
| Audio Signal Routing | Portable Data Acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NC SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4517ESA | Dual-supply operation (±5V), higher on-resistance (35Ω at ±5V), SO-8 package - no SOT23-5 variant available. | Required where bipolar signal swing or dual-rail systems exist; incompatible with single-supply-only layouts. | Select MAX4517ESA only if dual supplies are present and board space allows SO-8; not a drop-in replacement for MAX4515ESA. |
| TMUX1574DSGR | Single-supply (1.08V–4.5V), lower RON (0.5Ω typical at 3.3V), but higher off-leakage (100nA at +85°C) and no guaranteed 12V operation. | Better for ultra-low-voltage IoT sensors; unsuitable for 5V/12V industrial or audio systems requiring wide supply range. | Choose TMUX1574DSGR for sub-3.6V battery systems prioritizing RON; avoid where 12V tolerance or <20nA leakage is mandatory. |
Compared with MAX4515ESA, MAX4517ESA supports dual supplies but lacks SOT23-5 packaging and wider voltage range, while TMUX1574DSGR offers lower on-resistance at 3.3V but sacrifices high-voltage capability and leakage performance - making MAX4515ESA uniquely balanced for rugged, single-supply, low-leakage SPST switching.

FAQ
What is the maximum supply voltage rating for MAX4515ESA?
The MAX4515ESA has an absolute maximum V+ rating of +13V, with recommended continuous operation up to +12V. Operation beyond +12V risks permanent damage, and the device is fully specified from +2V to +12V - including guaranteed on-resistance, leakage, and timing parameters across this range. Always observe the -0.3V to (V+ + 0.3V) voltage limit on analog pins relative to GND.
Does MAX4515ESA support rail-to-rail analog signal switching?
Yes, the MAX4515ESA supports true rail-to-rail analog signal switching: input and output signals can swing from GND to V+ without distortion or clipping. This is enabled by its CMOS transmission-gate design and internal level-shifting logic, allowing seamless integration in systems where signal amplitude matches the supply rails - such as audio line drivers or sensor interfaces powered from the same rail.
What is the logic polarity of the control input on MAX4515ESA?
The IN pin of the MAX4515ESA is active-low: applying a logic LOW (≤0.8V) closes the normally closed (NC) switch path between COM and NC terminals, while a logic HIGH (≥2.4V at +5V supply) opens the path. This behavior is fixed per device type - MAX4515ESA is NC, whereas MAX4514ESA is NO - and cannot be reversed via external circuitry.
Can MAX4515ESA be used with a +3.3V supply?
Yes, the MAX4515ESA is fully functional at +3.3V: it meets all key specifications including on-resistance (≤50Ω), off-leakage (≤20nA at +85°C), and logic compatibility (0.8V–2.4V thresholds). However, on-resistance increases versus +5V/+12V operation, and charge injection rises slightly - verify signal integrity in high-precision 3.3V applications using the +3V supply characterization data in the datasheet.
Is the SOT23-5 package of MAX4515ESA lead-free and RoHS-compliant?
Yes, the MAX4515ESA in SOT23-5 packaging is lead-free and RoHS-compliant per Maxim Integrated's standard product release documentation. The device carries the "E" grade suffix (indicating -40°C to +85°C operation) and conforms to JEDEC J-STD-020 moisture sensitivity level 1 - requiring no bake prior to reflow. Full compliance documentation is available in Maxim's official product change notices.
