Analog Devices Inc./Maxim Integrated MAX4516EUK+T

Overview

MAX4516EUK+T 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, 1nA off-leakage at +25°C, and rail-to-rail signal handling - enabling precise signal routing in battery-powered audio/video systems and low-voltage data-acquisition circuits.

For engineers reviewing the MAX4516EUK+T datasheet, MAX4516EUK+T pinout, MAX4516EUK+T application, or MAX4516EUK+T equivalent, key selection criteria include guaranteed ±1V to ±6V dual-supply compatibility, SOT23-5 package constraints, NO switching behavior, and leakage-critical analog path integrity in portable instrumentation.

Technical Context

The MAX4516EUK+T uses fully differential CMOS switch architecture with independent V+ and V− supply rails driving both analog conduction paths and internal logic-level translators. Its digital input is referenced solely to V+, eliminating ground dependency and supporting true dual-supply logic interfacing.

All analog terminals (COM, NO, IN) feature reverse ESD diodes clamped to V+ and V−, making leakage current highly dependent on signal voltage relative to supply rails. On-resistance flatness (6Ω max) and charge injection (20pC max) are specified across full analog signal range (±4.5V at ±5V supplies), ensuring minimal distortion in precision AC-coupled paths.

FAQ

What is the maximum allowable analog signal voltage range for MAX4516EUK+T?

The MAX4516EUK+T supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this means −5V to +5V. Absolute maximum ratings allow V+ up to +13V and V− down to −0.3V, but analog signal must stay within V− to V+ to avoid forward-biasing internal ESD diodes. Exceeding V+ or V− risks damage and uncontrolled leakage.

Does MAX4516EUK+T require a ground connection?

No, the MAX4516EUK+T has no ground pin. Its digital input is referenced to V+, and analog operation depends only on the differential voltage between V+ and V−. This eliminates ground-loop concerns in isolated or floating analog subsystems, but requires all control logic to share the same V+ reference potential.

Can MAX4516EUK+T operate from a single supply?

The MAX4516EUK+T is designed for dual-supply operation (±1V to ±6V). While it may function with a single supply (e.g., V+ = +5V, V− = 0V), its guaranteed specifications - including RON, leakage, and switching speed - apply only under dual-supply conditions. For reliable single-supply use, Maxim recommends the pin-compatible MAX4514EUK+T instead.

What is the meaning of "NO" in MAX4516EUK+T?

"NO" stands for "normally open": the switch path between COM and NO is open (non-conductive) when the IN pin is logic LOW. When IN is driven HIGH (relative to V+), the path closes. This fail-safe behavior prevents unintended signal coupling during power-up or MCU reset, making MAX4516EUK+T suitable for safety-critical analog gating.

How does charge injection affect circuit performance in MAX4516EUK+T applications?

Charge injection (20pC max) causes a voltage glitch ΔVOUT = Q / CL on the switched node when the MAX4516EUK+T turns OFF. In a 100pF sampling capacitor, this yields a 200mV step - unacceptable for 12-bit+ ADCs. Mitigation requires minimizing CL, using correlated double sampling, or selecting switches with lower Q like the MAX4516EUK+T's 20pC spec versus older 50pC alternatives.
