Product details
Overview
MAX4695EGC+ from Maxim Integrated is a low-voltage, dual SPDT analog switch operating from a single +1.8V to +5.5V supply, delivering 60Ω max on-resistance at +2.7V, 30ns turn-on time, and rail-to-rail signal handling for audio/video routing in battery-powered MP3 players and cellular phones.
For engineers reviewing the MAX4695EGC+ datasheet, MAX4695EGC+ pinout, MAX4695EGC+ application, or MAX4695EGC+ equivalent, key selection criteria include guaranteed RON matching (≤3Ω), break-before-make timing (≤2ns), -82dB crosstalk at 1MHz, and 1.8V-logic compatibility with +2.7V to +3.3V supplies.
Technical Context
The MAX4695EGC+ integrates two independent SPDT switches with break-before-make switching action to prevent signal shorting during state transitions. Its CMOS architecture supports bidirectional analog signal flow across COM/NO/NC terminals with guaranteed RON flatness ≤10Ω over full signal range.
Digital control inputs accept 1.8V logic thresholds (VIL = 0.5V, VIH = 1.4V) at +2.7V–+3.3V supply, while analog channels handle rail-to-rail voltages (0V to V+) with <4pC charge injection and 0.03% THD at 2Vp-p.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct interface with Li-ion battery (3.0–3.7V) and 1.8V/3.3V logic domains |
| On-Resistance (RON) | 60Ω max at +2.7V - ensures minimal signal attenuation in low-voltage audio paths |
| RON Matching | 3Ω max between channels - critical for balanced differential signal routing without gain mismatch |
| Turn-On/Off Time | tON = 30ns, tOFF = 18ns at +3V - supports high-speed multiplexing in data-acquisition systems up to ~10MHz |
| Crosstalk | -82dB at 1MHz - prevents audible interference between adjacent audio channels |
| Off-Isolation | -75dB at 1MHz - blocks leakage from active to inactive signal paths in communication circuits |
| Charge Injection | 4pC max - minimizes voltage glitches on sampled-hold nodes in precision ADC front-ends |
Pinout & Package
MAX4695EGC+ is housed in a 3mm × 3mm, 12-pin Thin QFN package (TQFN-12) with exposed thermal pad for enhanced power dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Accept 1.8V CMOS logic; drive internal switch gates - must be driven before analog signals per sequencing guidelines |
| COM1, COM2 | Analog common terminals | Bidirectional signal path hubs - connect to source or load depending on routing configuration |
| NO1, NO2 | Normally open analog terminals | Connect to COM when corresponding IN is high - used for default-open signal paths |
| NC1, NC2 | Normally closed analog terminals | Connect to COM when corresponding IN is low - enable complementary switching topologies |
| V+ | Positive supply input | Single power rail for analog and digital sections - absolute max +6V; requires external decoupling |
| GND | Ground reference | Common return for all analog/digital currents - must be low-impedance to minimize THD degradation |
| Pins 6 & 10 | No connection (N.C.) | Not internally bonded - must remain unconnected per datasheet; no pull-up/down required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - essential for full-scale audio and sensor interfaces |
| Break-before-make switching | Guaranteed ≤2ns interval prevents momentary shorting between NO/NC paths - eliminates pop/click in audio switching |
| Low 4pC charge injection | Reduces voltage step on high-impedance nodes - preserves accuracy in sample-and-hold and multiplexed ADC applications |
| -3dB bandwidth >300MHz | Enables video signal routing (e.g., composite, S-video) without high-frequency roll-off |
| 1.8V logic compatibility | Operates with 1.8V microcontroller GPIOs at +2.7V–+3.3V supply - eliminates level-shifter components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4692ETE+ | Same 12-pin TQFN package; higher RON (120Ω max at +2.7V); slower tON/tOFF | Targeted at cost-sensitive, lower-bandwidth applications where 60Ω RON is not required | Select MAX4692ETE+ only if system tolerates higher on-resistance and reduced bandwidth |
| ADG726BRUZ | 16-pin TSSOP; 4.5Ω RON at +3V but requires dual ±1.8V supplies or +3.3V single supply; no 1.8V logic support | Suited for industrial instrumentation needing ultra-low RON, not portable battery-powered devices | Choose ADG726BRUZ only when ultra-low RON outweighs supply complexity and board area penalty |
Compared with MAX4692ETE+, MAX4695EGC+ delivers 2× lower RON and 2× faster switching for audio fidelity and data rate; versus ADG726BRUZ, it trades 1.8V logic compatibility and single-supply simplicity for slightly higher RON, making it optimal for portable consumer electronics.

FAQ
What is the maximum supply voltage rating for MAX4695EGC+?
The absolute maximum supply voltage (V+) for MAX4695EGC+ is +6V. Operation above this level risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V, with performance parameters like RON and switching speed optimized at +2.7V, +3V, and +5V. Always observe proper power-supply sequencing-apply V+ before analog signals-to avoid latch-up or ESD-induced failure in the MAX4695EGC+.
Does MAX4695EGC+ support true rail-to-rail analog signal switching?
Yes, MAX4695EGC+ supports rail-to-rail analog signal switching, meaning it passes signals from GND to V+ without clipping or distortion. This is confirmed by its analog signal range specification (0V to V+) and verified by typical operating characteristics showing stable RON across the full voltage range. The bidirectional nature of COM/NO/NC terminals allows flexible signal routing in either direction, making the MAX4695EGC+ suitable for both source- and load-side switching in audio and sensor interfaces.
What is the guaranteed on-resistance matching between the two SPDT channels of MAX4695EGC+?
The guaranteed on-resistance matching (∆RON) between the two SPDT channels of MAX4695EGC+ is ≤3Ω at +2.7V supply and +25°C, and ≤4Ω across the full temperature range (-40°C to +85°C). This tight matching ensures minimal gain error when routing differential or parallel signals, directly supporting high-fidelity audio and precision instrumentation applications where channel balance is critical in the MAX4695EGC+.
Can MAX4695EGC+ be used with 1.8V logic controllers powered from a +2.7V supply?
Yes, MAX4695EGC+ is explicitly designed for 1.8V logic compatibility when operated from a +2.7V to +3.3V supply, with VIL = 0.5V (max) and VIH = 1.4V (min) thresholds. This allows direct interfacing with 1.8V GPIOs from microcontrollers or FPGAs without level shifters. The MAX4695EGC+ datasheet confirms this behavior under "Digital I/O" specifications and "Digital Control Inputs" section, ensuring robust noise margins and low power consumption in portable systems.
What is the break-before-make timing specification for MAX4695EGC+?
The break-before-make (BBM) time for MAX4695EGC+ is guaranteed ≤2ns at both +3V and +5V supplies, measured under standard test conditions (VNO/VNC = +1.5V/+3V, RL = 300Ω, CL = 35pF). This ultra-short BBM interval prevents momentary shorting between normally open and normally closed paths, eliminating audible pop/click artifacts in audio switching and signal contention in data-routing applications using the MAX4695EGC+.
