Product details
Overview
MAX4695EGC+T 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+T datasheet, MAX4695EGC+T pinout, MAX4695EGC+T application, or MAX4695EGC+T 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+T implements two independent SPDT switches with break-before-make switching action, ensuring no signal shorting during state transitions. Each channel supports bidirectional analog signal flow across the full supply range (GND to V+), with guaranteed RON flatness ≤10Ω over the signal range and <4pC charge injection.
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 achieves >300MHz -3dB bandwidth and maintains high off-isolation (-75dB at 1MHz) while consuming only 1µA supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into low-power portable systems without level-shifting. |
| Max On-Resistance (RON) | 60Ω at +2.7V - ensures minimal signal attenuation and voltage drop in low-voltage audio paths. |
| RON Matching | ≤3Ω max between channels - critical for balanced differential signal routing and precision instrumentation. |
| Turn-On / Turn-Off Time | tON = 30ns, tOFF = 18ns at +3V - supports high-speed multiplexing in data-acquisition and communications circuits. |
| Crosstalk | -82dB at 1MHz - prevents audible interference between adjacent audio channels in MP3 players and handsets. |
| Off-Isolation | -75dB at 1MHz - blocks leakage from active to inactive signal paths in relay-replacement applications. |
| Charge Injection | 4pC - minimizes voltage glitches at COM pins during switching, preserving signal integrity in sample-hold circuits. |
Pinout & Package
MAX4695EGC+T is housed in a space-saving 3mm × 3mm, 12-pin Thin QFN package (TQFN) with exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital Control Inputs | CMOS/TTL-compatible logic inputs controlling Switch 1 and Switch 2 independently; low-threshold operation enables 1.8V system interfacing. |
| COM1, COM2 | Analog Common Terminals | Bidirectional signal ports connecting to source/destination nodes; support rail-to-rail analog swing (GND to V+). |
| NO1, NO2 | Normally Open Terminals | Signal paths closed when corresponding IN_ = logic high; used for default-open routing configurations. |
| NC1, NC2 | Normally Closed Terminals | Signal paths closed when corresponding IN_ = logic low; provides complementary switching states per channel. |
| V+ | Positive Supply Input | Single power rail for analog and digital sections; must be applied before analog signals to prevent latch-up. |
| GND | Ground Reference | Common return path for supply and analog signals; requires low-impedance PCB connection for noise immunity. |
| Pin 6 & Pin 10 | No Connection (N.C.) | Unbonded die pads - must remain unconnected on PCB; no internal circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping - essential for full-swing audio and sensor interfaces. |
| Break-before-make switching | Guaranteed ≤2ns dead time prevents momentary shorting between NO/NC paths - eliminates signal corruption in critical routing. |
| Low THD (0.03%) | Preserves audio fidelity in portable media devices by minimizing harmonic distortion across 20Hz–20kHz band. |
| 1.8V logic compatibility | Accepts 1.8V input thresholds at +2.7V to +3.3V supply - simplifies interface with modern low-voltage microcontrollers and FPGAs. |
| High off-isolation (-75dB) | Blocks coupling from active to inactive channels - improves channel separation in multi-source audio/video systems. |

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+ | Higher RON (120Ω max at +3V), slower tON/tOFF (60ns/40ns), same 12-pin TQFN package. | Targeted at cost-sensitive industrial controls where speed and on-resistance are less critical. | Select MAX4692ETE+ only if 60Ω RON and 30ns switching are not required. |
| ADG726BRUZ | Lower RON (4.5Ω typ at +5V), but higher supply minimum (+3V), no 1.8V logic compatibility, 24-pin TSSOP package. | Suited for high-precision instrumentation with ample board space and stable +5V rails. | Choose ADG726BRUZ when ultra-low RON and thermal stability outweigh size and low-voltage logic needs. |
Compared with MAX4692ETE+, the MAX4695EGC+T delivers half the on-resistance and twice the speed-critical for portable audio fidelity. Against ADG726BRUZ, it trades absolute RON performance for 1.8V logic support and 40% smaller footprint, making it optimal for space-constrained, battery-operated designs.

FAQ
What is the maximum supply voltage rating for MAX4695EGC+T?
The MAX4695EGC+T has an absolute maximum supply voltage (V+) of +6V. Operation beyond this limit risks permanent damage. For reliable long-term use, the recommended operating range remains +1.8V to +5.5V as specified in the datasheet. Exceeding +6V violates Absolute Maximum Ratings and may compromise internal ESD protection structures.
Does MAX4695EGC+T support bidirectional analog signal flow?
Yes, MAX4695EGC+T supports fully bidirectional analog signal routing on all COM_, NO_, and NC_ pins. Each switch channel passes signals equally well in either direction, with identical RON, leakage, and bandwidth specifications regardless of signal polarity-enabling flexible PCB layout and reuse in transmit/receive paths.
What is the guaranteed on-resistance matching between channels for MAX4695EGC+T?
The MAX4695EGC+T guarantees ≤3Ω maximum on-resistance matching (∆RON) between its two SPDT channels when operated at +2.7V supply and +25°C. This specification holds across the full temperature range (-40°C to +85°C) and ensures consistent gain and phase response in differential or parallel signal paths.
Can MAX4695EGC+T operate with a 1.8V logic input while powered from a 3.3V supply?
Yes, MAX4695EGC+T accepts 1.8V logic-high inputs (VIH ≥ 1.4V) when powered from a +2.7V to +3.3V supply. Its digital inputs are explicitly designed for 1.8V CMOS compatibility in this supply range, eliminating the need for external level shifters in mixed-voltage systems such as those using 1.8V FPGAs and 3.3V analog rails.
What is the thermal pad configuration for the MAX4695EGC+T TQFN package?
The MAX4695EGC+T uses a 12-pin Thin QFN package (3mm × 3mm × 0.8mm) with an exposed thermal pad on the underside. This pad must be soldered to a PCB copper pour for effective heat dissipation and mechanical stability. The datasheet specifies no electrical connection-only thermal and mechanical anchoring is required.
