Analog Devices Inc./Maxim Integrated MAX4616EGE

Overview

MAX4616EGE from Maxim Integrated is a quad, single-pole/single-throw (SPST) CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, operating from +2V to +5.5V. It delivers 10Ω max on-resistance at +5V, 12ns turn-on time, and rail-to-rail signal handling (GND to V+), enabling precise low-voltage signal routing in battery-powered audio and data-acquisition systems.

For engineers reviewing the MAX4616EGE datasheet, MAX4616EGE pinout, MAX4616EGE application, or MAX4616EGE equivalent, key selection criteria include guaranteed on-resistance matching (≤1Ω), <6nA off-leakage at +85°C, TTL/CMOS logic compatibility, and pin compatibility with 74HC4066/MAX4610 for drop-in replacement in legacy designs.

Technical Context

The MAX4616EGE integrates four independent SPST switches-two NO (IN1/IN3 control NO1/NO3) and two NC (IN2/IN4 control NC2/NC4)-with complementary logic states per channel. Its CMOS architecture ensures symmetrical conduction, flat on-resistance (<1Ω variation over full signal range), and bidirectional analog signal paths between COM and NO/NC terminals.

All digital inputs meet TTL/CMOS thresholds (+0.8V low, +2.4V high at +5V supply), and internal protection diodes clamp analog signals to within ±0.3V of GND/V+, supporting robust operation in mixed-signal environments without external clamping. The device is specified across –40°C to +85°C and supports rail-to-rail analog voltages up to V+.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for MAX4616EGE?

The MAX4616EGE has an absolute maximum supply voltage (V+) of +6V, but its recommended operating range is +2V to +5.5V. Operation above +5.5V risks permanent damage and violates the guaranteed specifications in the datasheet. For reliable long-term performance, maintain V+ within the specified 2V–5.5V window, especially in temperature-critical applications.

Does MAX4616EGE support rail-to-rail analog signal switching?

Yes, the MAX4616EGE supports true rail-to-rail analog signal handling: signals from GND to V+ can pass through any COM–NO or COM–NC path without clipping or distortion. This capability is inherent to its CMOS design and is verified across the full operating temperature range (–40°C to +85°C), making it ideal for single-supply systems where signal headroom is constrained.

How does the on-resistance matching specification apply to MAX4616EGE?

The MAX4616EGE guarantees on-resistance matching of ≤1Ω maximum between any two channels (ΔR_ON = R_ON(max) – R_ON(min)). This is measured under identical conditions (e.g., +5V supply, V_COM = 1V–4.5V) and ensures predictable gain/attenuation balance in multi-channel routing or differential signal paths-critical for instrumentation and measurement accuracy.

Can MAX4616EGE be used with a 3.3V microcontroller logic interface?

Yes, the MAX4616EGE accepts TTL/CMOS logic levels: at +5V supply, its input thresholds are +0.8V (V_{IN_L}) and +2.4V (V_{IN_H}), which are fully compatible with 3.3V GPIO outputs. Even at lower supplies (e.g., +3.3V), the device maintains valid logic recognition, ensuring robust control from modern low-voltage MCUs without external level translators.

What is the off-leakage current specification for MAX4616EGE at elevated temperature?

The MAX4616EGE specifies a maximum off-leakage current of 6nA at T_A = +85°C, tested across all NO and NC terminals. This value is 100% production-tested at hot temperature and correlated to +25°C performance. Such ultra-low leakage preserves signal integrity in high-impedance sample-and-hold circuits and sensor interfaces where even picoampere-level errors degrade accuracy.
