Analog Devices Inc./Maxim Integrated MAX4515EPA+

Overview

MAX4515EPA+ 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 a single +2V to +12V 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/video switching and low-voltage data-acquisition systems.

For engineers reviewing the MAX4515EPA+ datasheet, MAX4515EPA+ pinout, MAX4515EPA+ application, or MAX4515EPA+ equivalent, this page provides verified electrical parameters, thermal-rated performance (–40°C to +85°C), SOT23-5 and DIP package details, leakage behavior across temperature, and validated alternative parts for NC SPST analog switch selection.

Technical Context

The MAX4515EPA+ implements a CMOS transmission-gate architecture with internal level-shifting logic that translates TTL/CMOS input signals into full-rail gate drive for the analog switch. Its V+ and GND pins power both analog and digital sections, with ESD diodes clamping each signal terminal to V+ and GND - defining its absolute maximum analog voltage range as –0.3V to (V+ + 0.3V).

It features break-before-make timing (t_ON = 150ns, t_OFF = 100ns at +5V), 10pC charge injection, and guaranteed on-resistance flatness of ≤3Ω over signal range - enabling precision DC-coupled signal paths in instrumentation and communications circuits where signal integrity and minimal distortion are critical.

FAQ

What is the operating temperature range of the MAX4515EPA+?

The MAX4515EPA+ is rated for operation from –40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. The 'E' grade suffix explicitly denotes this temperature capability, distinguishing it from the 'C' grade (0°C to +70°C). All electrical specifications - including on-resistance, leakage current, and switching times - are guaranteed across this full range.

Does the MAX4515EPA+ support rail-to-rail analog signal switching?

Yes, the MAX4515EPA+ supports rail-to-rail analog signal switching. As stated in the General Description, "Each switch can handle rail-to-rail analog signals," meaning signals from GND to V+ pass without clipping. This is enabled by its CMOS transmission-gate architecture and internal level-shifting logic, which ensures full conduction across the entire supply range - a key feature validated in the Analog Signal Range parameter (0V to V+) across all supply voltages (+2V to +12V).

What is the maximum on-resistance of the MAX4515EPA+ at +5V supply?

The maximum on-resistance of the MAX4515EPA+ at +5V supply is 20Ω. This value is explicitly guaranteed in the Electrical Characteristics table under "On-Resistance" for V+ = +5V conditions (V+ = +4.5V to +5.5V, VCOM = 3.5V, ICOM = 1mA). The datasheet further confirms this is a production-tested limit, not just a typical value, ensuring design margin for precision analog paths.

How does the logic control interface of the MAX4515EPA+ work?

The MAX4515EPA+ uses an active-low digital control input (IN pin). When IN is low (≤0.8V), the NC switch closes, connecting COM to NC; when IN is high (≥2.4V at +5V supply), the switch opens. Its logic thresholds (0.8V to 2.4V) ensure TTL/CMOS compatibility with +5V systems. The internal level shifter converts this logic signal into full-rail gate drive - eliminating need for external translators and enabling direct interfacing with microcontrollers and FPGAs.

Is the MAX4515EPA+ pin-compatible with the MAX4514EPA+?

Yes, the MAX4515EPA+ is pin-compatible with the MAX4514EPA+. Both share identical 8-pin DIP pinouts: COM (pin 1), NC (pin 2), N.C. (pins 3,5,7), GND (pin 4), IN (pin 6), and V+ (pin 8). The only functional difference is their default state - MAX4515EPA+ is normally closed (NC), while MAX4514EPA+ is normally open (NO). This allows direct substitution in layouts where the required default state aligns with the application's safety or power-up behavior.
