Product details
Overview
The MAX4699ETE+ 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, featuring 75Ω max on-resistance at +3V, 35ns turn-on time, rail-to-rail signal handling, and break-before-make switching-used in audio/video routing and battery-powered portable equipment.
For engineers reviewing the MAX4699ETE+ datasheet, MAX4699ETE+ pinout, MAX4699ETE+ application, or MAX4699ETE+ equivalent, key selection criteria include guaranteed channel matching (≤4Ω), low leakage (≤1nA at +85°C), -76dB off-isolation at 1MHz, and compatibility with 1.8V logic inputs when powered from +3V.
Technical Context
The MAX4699ETE+ implements two independent DPDT switches, each controlled by dedicated digital inputs (IN1/IN2 for Switches 1–2; IN3/IN4 for Switches 3–4), enabling simultaneous configuration of four SPDT paths. Its CMOS architecture ensures bidirectional signal flow, rail-to-rail analog voltage support (0V to V+), and guaranteed break-before-make timing (≤1ns) to prevent transient shorting.
It operates without external logic supply-unlike the MAX4702-and uses standard TTL/CMOS-compatible control thresholds (VIH = +1.4V, VIL = +0.5V at +3V V+). On-resistance flatness remains ≤12Ω over full signal range, and crosstalk is limited to -79dB at 1MHz, supporting high-fidelity signal integrity in multi-channel routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply-enables direct integration into 1.8V, 2.7V, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 75Ω max at +3V supply-ensures minimal signal attenuation and voltage drop in low-power analog paths. |
| RON Matching | 4Ω max between channels-critical for balanced differential signaling and precision multiplexing. |
| Turn-On/Off Time | tON = 35ns, tOFF = 20ns at +3V-supports high-speed signal switching in audio, video, and data acquisition. |
| Off-Isolation | -76dB at 1MHz-prevents signal bleed between inactive channels in dense routing applications. |
| Leakage Current | ±1nA max at +85°C-maintains signal integrity in high-impedance sensor or bias networks over temperature. |
| Bandwidth | -3dB bandwidth = 250MHz-preserves signal fidelity up to UHF frequencies in RF-adjacent analog paths. |
Pinout & Package
The MAX4699ETE+ is housed in a 16-pin, 4mm × 4mm TQFN-EP package with exposed pad (EP) requiring connection to GND for thermal and electrical performance.

| 2 (V+) | Positive power supply input | Accepts +1.8V to +5.5V; powers internal switch core and level-shifting circuitry. |
| 3 (NC4) | Analog output - normally closed terminal of Switch 4 | Connected to COM4 when all control inputs are low; default path for fail-safe routing. |
| 4 (COM4) | Analog common terminal of Switch 4 | Central node for Switch 4; routes signals to NO4 or NC4 based on IN3/IN4 state. |
| 5 (NO4) | Analog output - normally open terminal of Switch 4 | Active path for Switch 4 when IN3/IN4 = logic high; complements NC4 for DPDT operation. |
| 6 (IN3, IN4) | Digital control inputs for Switches 3 and 4 | Independent TTL/CMOS-compatible inputs; high = connect COMx to NOx, low = connect COMx to NCx. |
| 7 (NC3) | Analog output - normally closed terminal of Switch 3 | Default path for Switch 3; maintains continuity during power-up or logic reset. |
| 8 (COM3) | Analog common terminal of Switch 3 | Shared signal node for Switch 3; supports bidirectional analog signal flow. |

| 11 (NC1) | Analog output - normally closed terminal of Switch 1 | Default path for Switch 1; ensures defined signal state before control activation. |
| 12 (COM2) | Analog common terminal of Switch 2 | Second independent common node; allows concurrent dual-path routing. |

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 3mm × 3mm TQFN package, identical DPDT topology and electrical specs-but lacks IN3/IN4 pins; uses shared IN1/IN2 for both switch pairs. | Reduced control flexibility: cannot independently toggle Switches 3–4; suited for synchronous dual-path routing only. | Select MAX4701ETE+ when board space is constrained and independent control of all four SPDT sections is unnecessary. |
| ADG732BRUZ | 32-channel SPST switch in 32-TSSOP; higher channel count but no DPDT structure-requires external logic to emulate break-before-make. | Not functionally equivalent: lacks native DPDT configuration, higher on-resistance (4.5Ω typ), and no guaranteed break-before-make timing. | Choose ADG732BRUZ only for high-channel-count, low-density routing where discrete control logic can manage sequencing. |
Compared with MAX4701ETE+, the MAX4699ETE+ offers independent control of all four SPDT sections via dedicated inputs, enabling asynchronous switching critical for fault-tolerant designs; versus ADG732BRUZ, it delivers native DPDT functionality with guaranteed break-before-make and lower leakage-making it superior for precision analog routing where channel coordination and signal integrity are paramount.

FAQ
What is the maximum supply voltage rating for the MAX4699ETE+?
The MAX4699ETE+ has an absolute maximum supply voltage (V+) of +6V. Operation is specified from +1.8V to +5.5V; exceeding +6V risks permanent damage. At +5.5V, on-resistance drops to 40Ω max, improving conduction efficiency in higher-voltage systems while maintaining compatibility with 5V logic domains.
Does the MAX4699ETE+ require a separate logic supply voltage (VL)?
No, the MAX4699ETE+ does not require a VL supply. Unlike the MAX4702, it derives all logic thresholds internally from V+. Its digital inputs are 1.8V-logic compatible when operated from a +3V supply, with VIH = +1.4V and VIL = +0.5V-eliminating the need for auxiliary voltage rails and simplifying system power architecture.
How is break-before-make timing guaranteed in the MAX4699ETE+?
The MAX4699ETE+ guarantees break-before-make timing of ≤1ns at +3V (TMIN to TMAX), verified by design and tested per Figure 3 in the datasheet. This is achieved through internal timing control circuitry that enforces a non-overlapping window between channel disconnect and reconnect-preventing momentary shorts in DPDT configurations critical for relay-replacement and signal integrity.
Can the MAX4699ETE+ handle analog signals beyond the supply rails?
No, the MAX4699ETE+ supports rail-to-rail analog signals only-from GND to V+. Voltages outside this range (e.g., negative signals or >V+) exceed absolute maximum ratings and may trigger internal ESD clamps, causing increased on-resistance or damage. External protection diodes (as shown in Figure 1) are required for overvoltage tolerance, but reduce usable signal range by ~0.7V.
What is the thermal significance of the exposed pad (EP) on the MAX4699ETE+ package?
The exposed pad (EP) on the MAX4699ETE+'s 4mm × 4mm TQFN package must be soldered to a GND plane to achieve rated thermal performance: 1666.7mW continuous power dissipation at +70°C with 20.8mW/°C derating above. Omitting EP connection reduces thermal capacity by >40%, risking junction temperature exceedance and parametric drift under sustained load.
