Product details
Overview
The MAX4695EUB+ 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 - used for audio/video routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4695EUB+ datasheet, MAX4695EUB+ pinout, MAX4695EUB+ application, or MAX4695EUB+ 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 MAX4695EUB+ implements two independent CMOS SPDT switches with break-before-make switching action, ensuring no signal shorting during state transitions. Each channel supports bidirectional analog signals spanning GND to V+, with guaranteed RON flatness ≤10Ω over full signal range and charge injection as low as 4pC.
Its digital control inputs accept 1.8V CMOS logic levels when powered from +2.7V to +3.3V, and TTL-compatible thresholds at +5V. The device features low leakage (±1nA off-state, ±2nA on-state) and high-frequency performance: >300MHz -3dB bandwidth and -75dB off-isolation at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct interface with Li-ion, 3.3V, and 5V systems without level shifting. |
| On-Resistance (RON) | 60Ω max at +2.7V - ensures minimal signal attenuation and gain error in precision sensor or audio paths. |
| RON Matching | 3Ω max between channels - critical for balanced differential signal routing and multiplexer accuracy. |
| Turn-On / Turn-Off Time | tON = 30ns, tOFF = 18ns at +3V - supports high-speed signal switching in data acquisition and communications circuits. |
| Crosstalk | -82dB at 1MHz - prevents interference between adjacent switched channels in multi-signal routing applications. |
| Off-Isolation | -75dB at 1MHz - maintains signal integrity by suppressing coupling from active to inactive channels. |
| Charge Injection | 4pC max - minimizes voltage glitches at COM pins during switching, essential for sample-and-hold and ADC front-ends. |
Pinout & Package
MAX4695EUB+ uses the 10-pin µMAX® package (3.0mm × 3.0mm × 0.8mm, exposed pad), optimized for space-constrained portable designs. Pin numbering follows JEDEC MS-012 standard with Pin 1 marked by dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Switch 1 | Active-high logic input; drives NO1/NC1 connection state; 1.8V CMOS compatible at +2.7V–+3.3V V+. |
| 2 (NO1) | Normally open terminal, Switch 1 | Analog path connected to COM1 only when IN1 = high; bidirectional signal pin with RON ≤60Ω. |
| 3 (GND) | Ground reference | Primary return path for analog and digital circuitry; must be low-impedance for THD <0.03% performance. |
| 4 (NO2) | Normally open terminal, Switch 2 | Independent analog path for second SPDT; matched RON and flatness to Switch 1 for synchronized routing. |
| 5 (IN2) | Digital control input for Switch 2 | Independent logic control; allows asynchronous switching of dual channels without shared timing constraints. |
| 6 (COM2) | Common terminal, Switch 2 | Central analog node for Switch 2; handles bidirectional signals up to rail-to-rail (GND to V+). |
| 7–8 (N.C.) | No connection | Unbonded pins; must remain unconnected per datasheet - no internal function or thermal role. |
| 9 (NC1) | Normally closed terminal, Switch 1 | Connected to COM1 when IN1 = low; complements NO1 for true SPDT functionality in relay-replacement use cases. |
| 10 (COM1) | Common terminal, Switch 1 | Primary analog I/O node for Switch 1; shares same RON, leakage, and bandwidth specs as COM2. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from GND to V+ without clipping - enables direct interfacing with op-amps and ADCs across full supply range. |
| Break-before-make switching | Guaranteed tBBM ≤2ns prevents momentary shorting between NO and NC paths - critical for avoiding signal corruption in audio/video muxes. |
| Low THD (0.03%) | Preserves audio fidelity in MP3 players and cellular handsets by minimizing harmonic distortion in 20Hz–20kHz band. |
| 1.8V logic compatibility | Accepts standard low-voltage logic thresholds (VIH = 1.4V, VIL = 0.5V) at +2.7V supply - eliminates need for external level shifters in modern SoC interfaces. |
| High off-isolation (-75dB) | Blocks unwanted signal coupling between channels at 1MHz - essential for maintaining SNR in communication circuits and PCMCIA card signal routing. |

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 |
|---|---|---|---|

FAQ
What is the maximum supply voltage rating for the MAX4695EUB+?
The MAX4695EUB+ has an absolute maximum supply voltage (V+) of +6V. Operation beyond this limit risks permanent damage. The recommended operating range is +1.8V to +5.5V. At +5.5V, the device delivers 25Ω typical on-resistance and maintains full specification compliance across -40°C to +85°C. Always apply V+ before analog signals to prevent latch-up or ESD stress.
Does the MAX4695EUB+ support true break-before-make switching, and is it guaranteed?
Yes, the MAX4695EUB+ guarantees break-before-make (BBM) switching with tBBM ≤2ns at both +3V and +5V supplies, confirmed in the Electrical Characteristics tables. This prevents momentary shorting between NO and NC terminals during state transitions - a critical requirement for protecting downstream circuitry in audio, communications, and data-acquisition applications.
Can the MAX4695EUB+ operate with 1.8V logic inputs while powered from a 2.7V supply?
Yes. When powered from +2.7V to +3.3V, the MAX4695EUB+ accepts 1.8V CMOS logic levels: VIH = +1.4V (min), VIL = +0.5V (max). This eliminates external level shifters in modern low-voltage SoC designs. Input leakage remains ≤±1µA, and logic thresholds track supply voltage linearly per Figure 9 in the datasheet.
What is the typical on-resistance flatness of the MAX4695EUB+ over its analog signal range?
The MAX4695EUB+ guarantees RON flatness ≤10Ω max over the full analog signal range (GND to V+) when powered from +2.7V. At +5V, flatness improves to ≤8Ω max. This tight variation ensures consistent gain and minimal distortion across the signal swing - vital for precision instrumentation and high-fidelity audio routing where amplitude accuracy is critical.
How does the MAX4695EUB+ perform in terms of off-isolation and crosstalk at 1MHz?
At 1MHz, the MAX4695EUB+ delivers -75dB off-isolation (COM to OFF-state NO/NC) and -82dB crosstalk (between active and inactive channels), both measured with 50Ω source/load and 5pF stray capacitance. These values are guaranteed across -40°C to +85°C and ensure signal integrity in dense PCB layouts and multi-channel routing applications like PCMCIA cards and cellular baseband switching.
