Product details
Overview
The MAX4699EGE from Maxim Integrated is a low-voltage, dual double-pole/double-throw (DPDT) CMOS analog switch operating from a single +1.8V to +5.5V supply. It delivers 75Ω max on-resistance at +3V, 35ns turn-on time, rail-to-rail signal handling, and break-before-make switching-enabling precise audio/video signal routing in space-constrained portable devices.
For engineers reviewing the MAX4699EGE datasheet, MAX4699EGE pinout, MAX4699EGE application, or MAX4699EGE equivalent, this device supports high-fidelity signal path selection in battery-powered equipment where low leakage (<1nA), tight channel matching (≤4Ω), and 250MHz bandwidth are critical design requirements.
Technical Context
The MAX4699EGE implements two independent DPDT switches, each controlled by dedicated logic inputs (IN1/IN2 for Switches 1–2; IN3/IN4 for Switches 3–4), enabling simultaneous reconfiguration of two bidirectional signal paths. Its CMOS architecture ensures rail-to-rail analog conduction with guaranteed break-before-make timing (≤1ns) to prevent signal shorting during transition.
It operates without external logic supply-digital inputs are 1.8V-logic compatible at +3V V+, eliminating need for level shifters. On-resistance flatness remains ≤12Ω over full signal range (0V to V+), and off-isolation reaches –76dB at 1MHz, supporting clean multiplexing in sensitive analog front-ends.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4701ETE | Same dual-DPDT function but in 3mm × 3mm TQFN; 1.8V-logic compatible; identical RON (75Ω max @ +3V) and timing specs. | Smaller footprint (3×3mm vs. 4×4mm); same temperature range (–40°C to +85°C); RoHS-compliant variant available. | Select MAX4701ETE when board space is constrained and 3mm × 3mm package compatibility is verified. |
| ADG732BRUZ | 32-channel SPST switch (not DPDT); 4.5Ω RON @ +3V; 12ns tON; requires separate logic supply for 1.8V interface. | Higher channel count but different topology-suited for large-scale multiplexing, not DPDT signal inversion or swapping. | Choose ADG732BRUZ only for high-density SPST routing; not a functional replacement for MAX4699EGE's dual-DPDT architecture. |
Compared with MAX4701ETE, the MAX4699EGE offers identical electrical performance in a larger 4×4mm package-beneficial for thermal management and hand-soldering. Versus ADG732BRUZ, it provides native DPDT functionality without external logic or layout redesign, simplifying stereo/audio path control.

FAQ
What is the maximum supply voltage rating for the MAX4699EGE?
The MAX4699EGE has an absolute maximum supply voltage (V+) of +6V, but its specified operational range is +1.8V to +5.5V. Operating beyond +5.5V risks permanent damage and violates the device's guaranteed specifications-including on-resistance, leakage, and switching speed-so +5.5V is the recommended upper limit for reliable long-term use of the MAX4699EGE.
Does the MAX4699EGE require a separate logic supply voltage?
No, the MAX4699EGE does not require a separate logic supply. Its digital inputs (IN1–IN4) are 1.8V-logic compatible when operated from a +3V analog supply, eliminating the need for VL or level-shifting circuitry. This distinguishes it from the MAX4702, which mandates a dedicated VL input-confirming that the MAX4699EGE functions with a single +1.8V to +5.5V rail.
What is the guaranteed break-before-make interval for the MAX4699EGE?
The MAX4699EGE guarantees a break-before-make (BBM) interval of ≤1ns under typical conditions (+2.7V to +3.3V supply, 25°C), measured with RL = 300Ω and CL = 35pF. This ultra-short BBM time prevents signal shorting during state transitions and is validated across the full –40°C to +85°C temperature range-ensuring robust operation in the MAX4699EGE's target applications.
Can the MAX4699EGE handle rail-to-rail analog signals?
Yes, the MAX4699EGE supports true rail-to-rail analog signal handling-from GND to V+-with minimal variation in on-resistance across the full range. This capability is confirmed in the Typical Operating Characteristics (Figures toc01–toc04), where RON remains stable even at VCOM = 0V or VCOM = V+, making the MAX4699EGE suitable for unipolar and bipolar signal paths without external biasing.
What package variant does the MAX4699EGE use, and is it RoHS-compliant?
The MAX4699EGE uses a 16-pin, 4mm × 4mm × 0.9mm TQFN package (drawing 21-0106E, variant G1644-1). Per Maxim's official part number table, this variant is **not RoHS/lead-free**-unlike the MAX4699ETE+ variant, which uses a thinner 0.8mm TQFN and carries the '+' suffix indicating RoHS compliance. Therefore, the MAX4699EGE requires leaded assembly processes.
