Product details
Overview
MAX4516CUK from Maxim Integrated is a single-pole/single-throw (SPST), normally open (NO), CMOS analog switch optimized for low-voltage dual-supply operation. It delivers 20Ω on-resistance at ±5V supplies, 1nA off-leakage at +25°C, and rail-to-rail signal handling across ±1V to ±6V supplies-enabling precise signal routing in battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4516CUK datasheet, MAX4516CUK pinout, MAX4516CUK application, or MAX4516CUK equivalent, key selection criteria include guaranteed on-resistance flatness (6Ω), fast switching (tON = 100ns), low charge injection (20pC max), and SOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The MAX4516CUK implements a CMOS transmission-gate architecture with separate V+ and V− supply pins that define both analog signal range and internal logic thresholds. Its digital input is referenced to V+, supporting CMOS-compatible logic levels without a ground reference.
Internal ESD diodes clamp analog pins to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. The device exhibits tON > tOFF behavior at ±5V and maintains stable on-resistance over temperature (±125°C max) and supply voltage variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 20Ω max at ±5V - ensures minimal signal attenuation in precision analog paths |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces |
| Supply Range | ±1V to ±6V dual - supports ultra-low-voltage battery operation down to ±1V |
| Switching Speed | tON = 100ns, tOFF = 75ns - enables reliable timing in multiplexed data acquisition |
| Charge Injection | 20pC max - minimizes voltage glitch during switching in sample-and-hold circuits |
| On-Resistance Flatness | 6Ω max - maintains consistent gain/attenuation across full analog signal range |
| Analog Signal Range | Rail-to-rail (V− to V+) - allows full utilization of supply headroom in bipolar signal chains |
Pinout & Package
MAX4516CUK is housed in a 5-pin SOT23-5 package with exposed pad not internally connected. Pin 1 = IN (digital control), Pin 2 = NO (normally open switch terminal), Pin 3 = V− (negative supply), Pin 4 = COM (common analog terminal), Pin 5 = V+ (positive supply). No internal connections exist at unused positions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Digital control input | CMOS-compatible logic input referenced to V+; drives internal gate transistors |
| NO (Pin 2) | Normally open analog terminal | Connects to COM only when IN = HIGH; bidirectional signal path |
| V− (Pin 3) | Negative supply rail | Sets lower analog voltage limit and powers internal logic; clamped by ESD diodes |
| COM (Pin 4) | Common analog terminal | Primary signal I/O node; interchangeable as input or output in bidirectional operation |
| V+ (Pin 5) | Positive supply rail | Sets upper analog voltage limit and powers internal logic; defines logic threshold reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4514CUK | Single-supply only (+2V to +12V); no V− pin; logic threshold referenced to GND | Designed for systems with grounded logic domains and unipolar supplies | Select when V− rail is unavailable and logic interface uses standard 0V/GND reference |
| ADG1219BRMZ | Higher RON (120Ω typ), wider temp range (−40°C to +125°C), different pinout (SOIC-8) | Targeted at industrial environments requiring extended temperature operation and higher ESD robustness | Choose for harsh environments where guaranteed 120Ω RON is acceptable and SOIC-8 layout is feasible |
Compared with MAX4516CUK, MAX4514CUK eliminates the negative supply but sacrifices dual-rail flexibility and rail-to-rail analog range, while ADG1219BRMZ trades on-resistance and package size for broader temperature coverage and industrial-grade reliability-making MAX4516CUK optimal for compact, battery-powered designs demanding low RON and bipolar signal handling.

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power-management ICs for demanding industrial, communications, and consumer applications.
The MAX4516/MAX4517 family was engineered specifically for low-voltage, low-leakage, rail-to-rail analog switching in portable and battery-sensitive systems-prioritizing on-resistance stability, charge injection control, and dual-supply flexibility over raw speed or high-voltage tolerance.
FAQ
What is the maximum supply voltage range supported by the MAX4516CUK?
The MAX4516CUK operates continuously with dual supplies from ±1V up to ±6V. Absolute maximum ratings allow V+ up to +13V and V− down to −0.3V, but guaranteed performance-including on-resistance, leakage, and switching speed-is specified only across the ±1V to ±6V range. For reliable operation, maintain supplies within ±5.5V per the electrical characteristics table.
Is the MAX4516CUK pin-compatible with other devices in the MAX4516/MAX4517 family?
Yes-the MAX4516CUK shares identical pinout and functionality with all SOT23-5 variants in the MAX4516 series (e.g., MAX4516EUK, MAX4516CSA), differing only in temperature grade and packaging markings. It is not pin-compatible with DIP or SO packages due to different pin counts and layouts, nor with MAX4517 variants which have inverted logic control (NC instead of NO).
How does the logic-level input of the MAX4516CUK interface with standard 3.3V or 5V microcontrollers?
The MAX4516CUK's IN pin is referenced to V+, not ground-so its logic thresholds scale with V+. At V+ = +5V, VIH = 3.5V and VIL = 1.5V, making it compatible with 5V CMOS outputs. At V+ = +3.3V, thresholds shift proportionally (~2.3V/0.8V), requiring level matching if driven by 5V logic. Direct connection to 5V TTL may exceed absolute maximum ratings and is not recommended.
Can the MAX4516CUK handle AC-coupled audio signals without distortion?
Yes-the MAX4516CUK supports rail-to-rail analog signals and exhibits low total harmonic distortion (<0.01% at 1kHz) due to its 20Ω RON, 6Ω flatness, and symmetric charge injection. When used with proper biasing (e.g., DC restoration or coupling capacitors), it maintains signal fidelity across the audio band (20Hz–20kHz) with >86dB off-isolation at 100kHz.
What thermal considerations apply to the MAX4516CUK in continuous operation?
The MAX4516CUK has a thermal derating factor of 7.1mW/°C above +70°C in SOT23-5 package, with maximum continuous power dissipation of 571mW at TA = +70°C. Junction temperature must remain below +150°C; for ambient temperatures up to +85°C, keep total power below ~450mW. Layout should include adequate copper pour on V+ and V− pads to enhance heat dissipation.
