Analog Devices Inc./Maxim Integrated MAX4693EGE

Overview

MAX4693EGE from Maxim Integrated is a triple single-pole/double-throw (SPDT) analog switch IC configured for bidirectional rail-to-rail signal routing. It operates from single +2V to +11V or dual ±2V to ±5.5V supplies, delivers 25Ω max on-resistance at ±4.5V, guarantees break-before-make switching, and supports 1.8V logic compatibility at +3V supply - ideal for low-voltage audio/video routing in portable communications equipment.

For engineers reviewing the MAX4693EGE datasheet, MAX4693EGE pinout, MAX4693EGE application, or MAX4693EGE equivalent, key selection criteria include guaranteed channel-to-channel R_ON matching (≤3Ω at ±4.5V), low 1nA leakage current, fast 90ns transition time, and QFN-EP package compatibility with high-density PCB layouts.

Technical Context

The MAX4693EGE implements three independent SPDT switches, each with dedicated digital control inputs (A, B, C) and common terminals (X, Y, Z). Its CMOS architecture enables rail-to-rail analog signal handling across V+ and V−, with internal level translators supporting 1.8V/3V/5V logic interfaces without external biasing.

Break-before-make timing is guaranteed at ≤2ns, preventing signal shorting during state transitions. The device uses reverse-biased ESD diodes between each analog pin and V+/V− to clamp overvoltage, with leakage current dominated by differential diode conduction rather than channel conduction.

Key Specifications

Pinout & Package

The MAX4693EGE is housed in a 16-pin QFN-EP (4mm × 4mm) package with exposed pad connected to V+. Pin functions are validated per Maxim's official datasheet Rev 6 (1/2012).

FAQ

What supply configurations does the MAX4693EGE support?

The MAX4693EGE supports both single-supply operation from +2V to +11V (with V− tied to GND) and dual-supply operation from ±2V to ±5.5V. At ±4.5V, it achieves 25Ω max on-resistance and 3Ω max R_ON matching. The MAX4693EGE datasheet specifies absolute maximum ratings up to +12V differential (V+ − V−), but operation beyond ±5.5V is not characterized.

Does the MAX4693EGE require external level shifters for 1.8V logic control?

No. The MAX4693EGE features built-in logic-level translators that accept 1.8V logic inputs when operated from a +3V supply, and TTL-compatible inputs at +5V. This eliminates external level shifters in mixed-voltage systems. The MAX4693EGE pinout assigns A, B, and C directly to GPIOs without additional conditioning.

How is break-before-make timing ensured in the MAX4693EGE?

The MAX4693EGE guarantees break-before-make timing of ≤2ns across temperature and supply conditions, as verified in the datasheet's Figure 4 test circuit. This is achieved through internal timing control circuitry that delays connection of the new path until the previous path is fully disconnected - preventing transient shorts in critical analog routing.

Can the MAX4693EGE handle bipolar analog signals in single-supply mode?

No. In single-supply mode (V− = GND), the MAX4693EGE supports rail-to-rail analog signals from 0V to V+, not below ground. Bipolar signal handling requires dual-supply operation with V− negative. The MAX4693EGE analog signal range is strictly bounded by V− and V+, with no capability to pass signals outside that window.

What is the thermal performance advantage of the MAX4693EGE's QFN-EP package?

The MAX4693EGE's 16-pin QFN-EP package includes an exposed pad thermally connected to V+, providing 1481mW continuous power dissipation at +70°C (derated 18.5mW/°C above). This exceeds the 659mW rating of the UCSP variant, making the MAX4693EGE better suited for sustained switching in thermally demanding modem or instrumentation applications.
