Product details
Overview
MAX4679EUE+ from Analog Devices is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring guaranteed break-before-make switching, 1.6Ω max on-resistance at ±5V dual supply, 0.3Ω max on-resistance matching, and rail-to-rail signal handling for precision audio and test equipment signal routing.
For engineers reviewing the MAX4679EUE+ datasheet, MAX4679EUE+ pinout, MAX4679EUE+ application, or MAX4679EUE+ equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases in ADC systems and communications infrastructure, and validated alternative options for design continuity.
Technical Context
The MAX4679EUE+ implements CMOS-based SPST switches with independent logic supply (VL) supporting 2.7V to V+, enabling separation of analog and digital domains. Its break-before-make timing is guaranteed at 5ns under RL = 300Ω/CL = 35pF conditions - a critical feature distinguishing it from the MAX4677/MAX4678 variants.
It operates across dual ±2.7V to ±5.5V or single +2.7V to +11V supplies, delivering 66MHz -3dB bandwidth and -84dB crosstalk at 1MHz. Off-isolation is -65dB at 1MHz, and charge injection is 85pC (dual supply) or 9pC (single supply), directly impacting settling accuracy in data-acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.6Ω max at ±5V dual supply - ensures minimal voltage drop and signal attenuation in low-level analog paths. |
| On-Resistance Matching | 0.3Ω max between channels - enables precise channel-to-channel signal balancing in multiplexed sensor or calibration systems. |
| Break-Before-Make Delay | 5ns guaranteed - prevents momentary shorting during channel switching, essential for fault-tolerant signal routing. |
| -3dB Bandwidth | 66MHz (dual supply) - supports high-fidelity audio, video, and intermediate-frequency signal switching without roll-off. |
| Off-Isolation | -65dB at 1MHz - suppresses crosstalk between inactive and active channels in dense PCB layouts. |
| Logic Supply Range (VL) | +2.7V to V+ - allows independent level-shifting of control inputs, simplifying interface with mixed-voltage microcontrollers. |
| Supply Voltage Range | Dual ±2.7V to ±5.5V or single +2.7V to +11V - supports both bipolar instrumentation and unipolar industrial I/O designs. |
Pinout & Package
MAX4679EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5mm body, 0.65mm pitch), rated for -40°C to +85°C operation. Thermal resistance is 5.7mW/°C above +70°C (457mW max continuous dissipation at TA = +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1,8,9,16) | Logic Control Inputs | TTL/CMOS-compatible; drive internal gate drivers; VL-referenced threshold (VIH = 2.4V, VIL = 0.8V at VL = V+). |
| COM1–COM4 (Pins 2,7,10,15) | Analog Common Terminals | Switch current path endpoints; support ±5.5V analog swing (V- to V+) and ±100mA continuous current. |
| NO1, NO4 (Pins 3,6) | Normally Open Switch Terminals | Connect to COM only when corresponding IN = logic high; isolated from COM when IN = low. |
| NC2, NC3 (Pins 11,14) | Normally Closed Switch Terminals | Connected to COM when corresponding IN = logic low; disconnect when IN = high - enables fail-safe default paths. |
| V+ (Pin 13) | Positive Analog Supply | Accepts +2.7V to +11V (single) or +2.7V to +5.5V (dual); must be powered before V- and VL per sequencing guidelines. |
| V- (Pin 4) | Negative Analog Supply | Accepts -2.7V to -5.5V (dual); tie to GND for single-supply operation; absolute max rating: -12V. |
| GND (Pin 5) | Analog/Digital Ground Reference | Common return for V+, V-, VL, and logic inputs; requires low-impedance connection to minimize noise coupling. |
| VL (Pin 12) | Logic Supply Input | Independent bias for input thresholds; range = +2.7V to V+; decoupling recommended to reduce digital switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 5ns delay ensures no overlap between NC and NO conduction - eliminates signal shorting in reconfigurable filter or gain-switching circuits. |
| Rail-to-rail analog signal range | V- to V+ operation supports full dynamic range of ±5V op-amps and ADC drivers without clipping or distortion. |
| Low on-resistance flatness | 0.4Ω max variation over signal range - maintains consistent gain and linearity across input voltage span in precision instrumentation. |
| Ultra-low off-leakage | 0.1nA max at +25°C - preserves high-impedance node integrity in sensor front-ends and electrometer-grade measurement paths. |
| High-speed switching | 350ns max turn-on / 150ns max turn-off (dual supply) - enables rapid channel scanning in automated test equipment at >1MHz update rates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4678EUE+ | Four NO-only channels; no break-before-make; identical RON, bandwidth, and supply specs. | Suitable where all switches must be open by default; lacks fail-safe NC paths required in safety-critical routing. | Select MAX4678EUE+ only when fully NO functionality suffices and break-before-make is unnecessary. |
| ADG1419BRUZ | Quad SPDT with 1.8Ω RON, ±15V tolerant, but no guaranteed break-before-make; higher leakage (±2nA). | Better for high-voltage industrial I/O; unsuitable for low-leakage precision ADC front-ends or tight-timing reconfiguration. | Choose ADG1419BRUZ when ±15V signal handling is mandatory and 5ns tBBM is not required. |
Compared with MAX4678EUE+, the MAX4679EUE+ adds deterministic break-before-make and NC/NO mixing at identical RON and bandwidth - making it uniquely suited for fault-aware signal routing. Against ADG1419BRUZ, it trades voltage range for lower leakage, tighter matching, and guaranteed timing control in sub-10ns critical paths.

FAQ
What is the guaranteed break-before-make timing for MAX4679EUE+?
The MAX4679EUE+ guarantees a 5ns break-before-make delay under RL = 300Ω and CL = 35pF load conditions, as specified in the datasheet Figure 3. This parameter is unique to the MAX4679EUE+ within the MAX4677/78/79 family and is not offered by the MAX4677EUE+ or MAX4678EUE+. The timing ensures no overlap between NC and NO conduction during switching transitions in the MAX4679EUE+.
Does MAX4679EUE+ support single-supply operation?
Yes, the MAX4679EUE+ supports single-supply operation from +2.7V to +11V with V- tied to GND. In this mode, the analog signal range is 0V to V+, and key specs shift slightly: on-resistance increases to 2.7Ω max (typical), -3dB bandwidth reduces to 63MHz, and off-isolation remains -65dB at 1MHz. All logic inputs remain compatible with VL = 2.7V to V+.
What is the maximum allowable voltage difference between V+ and V- for MAX4679EUE+?
The absolute maximum rating for V+ to V- differential is +12V. However, the recommended operating range is ±2.7V to ±5.5V (i.e., ≤11V total). Exceeding 11V risks violating internal device limits and may cause permanent damage. The datasheet explicitly states "V+ to V- ................................................................................+12V" under Absolute Maximum Ratings but specifies "Dual ±2.7V to ±5.5V" as the functional operating range for the MAX4679EUE+.
How does the logic supply VL affect input thresholds in MAX4679EUE+?
The VL pin sets the reference for logic input thresholds: VIH = 2.4V and VIL = 0.8V are guaranteed when VL = V+. If VL is set lower (e.g., 3.3V), thresholds scale proportionally - confirmed by the "INPUT THRESHOLD vs. LOGIC SUPPLY" curve (Figure 10), showing VTH(rising) ≈ 0.7 × VL. This allows flexible interfacing with 1.8V, 3.3V, or 5V controllers while maintaining noise margin in the MAX4679EUE+.
Can MAX4679EUE+ handle bipolar analog signals beyond ±5V?
No - the MAX4679EUE+ supports analog signals only from V- to V+, and its absolute maximum ratings limit V+ to +12V and V- to -12V. For operation at ±5V supplies, the signal range is strictly -5V to +5V. Attempting ±12V signals would exceed the ±5.5V max dual-supply rating and violate the "VCOM_, VNO_, VNC_ = V- to V+" specification. Higher-voltage alternatives like ADG1419BRUZ are required for ±15V operation.
