Product details
Overview
MAX4695ETC+TGC1 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 portable electronics.
For engineers reviewing the MAX4695ETC+TGC1 datasheet, MAX4695ETC+TGC1 pinout, MAX4695ETC+TGC1 application, or MAX4695ETC+TGC1 equivalent, key selection criteria include guaranteed RON matching (≤3Ω), break-before-make timing (≤2ns), -82dB crosstalk at 1MHz, and compatibility with 1.8V logic inputs when powered from +2.7V to +3.3V supplies.
Technical Context
The MAX4695ETC+TGC1 implements two independent CMOS SPDT switches with break-before-make switching action, ensuring no momentary short between NC and NO paths during state transitions. Its architecture supports bidirectional analog signal routing across the full V+ to GND range with minimal distortion (THD = 0.03%).
Each channel features matched on-resistance (ΔRON ≤ 3Ω max) and flat RON over signal range (≤10Ω max), enabling precision signal path selection in low-voltage data-acquisition systems. The device uses internal level-shifting circuitry to maintain 1.8V-logic compatibility across its +2.7V to +3.3V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 1.8V/2.5V/3.3V/5V systems without level shifters |
| 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 and instrumentation applications |
| Turn-On / Turn-Off Time | 30ns / 18ns at +3V - supports high-speed multiplexing in communications circuits and PCMCIA card switching |
| Crosstalk | -82dB at 1MHz - prevents interference between adjacent switched audio or video channels |
| Off-Isolation | -75dB at 1MHz - maintains signal integrity by suppressing leakage from inactive paths |
| Charge Injection | 4pC - minimizes voltage glitches in precision sampling and data-acquisition front-ends |
Pinout & Package
MAX4695ETC+TGC1 is housed in a 12-pin 3mm × 3mm thin QFN package (TQFN) with exposed thermal pad, optimized for space-constrained portable designs and offering superior thermal performance versus µMAX alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Accept 1.8V CMOS logic levels; active-high control for respective SPDT switches |
| COM1, COM2 | Analog common terminals | Bidirectional signal ports - serve as input or output depending on switch state |
| NO1, NO2 | Normally open analog terminals | Connected to COMx only when corresponding INx = high; default open state |
| NC1, NC2 | Normally closed analog terminals | Connected to COMx only when corresponding INx = low; default closed state |
| V+ | Positive supply rail | Single power source for analog and digital sections; must be applied before analog signals |
| GND | Ground reference | Common return for supply, logic, and analog signals; requires low-impedance PCB connection |
| NC (Pins 6, 10) | No-connect terminals | Not internally bonded - must remain unconnected on PCB to avoid parasitic coupling |
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 signal shorting during channel transitions - required for relay replacement |
| Low THD (0.03%) | Preserves audio fidelity in MP3 players and cellular handsets by minimizing harmonic distortion |
| High off-isolation (-75dB) | Blocks unwanted signal coupling between active and inactive paths in communications circuits |

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 |
|---|---|---|---|
| MAX4692ETC+ | Higher RON (120Ω max at +2.7V), slower switching (tON = 45ns), same 12-pin TQFN package | Targeted at cost-sensitive, lower-performance portable equipment where signal fidelity is less critical | Select MAX4692ETC+ only if 60Ω RON and 30ns speed are not required - avoids over-specifying |
| ADG726BRUZ | Lower RON (4.5Ω typ at +3V), but higher charge injection (12pC), 16-pin TSSOP package, 1.8V–5.5V supply | Suitable for precision instrumentation where low RON dominates over glitch energy | Choose ADG726BRUZ when sub-5Ω RON is mandatory and PCB layout accommodates larger TSSOP footprint |
Compared with MAX4692ETC+, MAX4695ETC+TGC1 delivers tighter RON matching and faster switching for audio-grade routing; versus ADG726BRUZ, it trades some RON for significantly lower charge injection and smaller 3×3mm QFN footprint - ideal for space-constrained mobile designs.

FAQ
What is the maximum supply voltage rating for MAX4695ETC+TGC1?
The absolute maximum supply voltage (V+) for MAX4695ETC+TGC1 is +6V. However, the recommended operating range is +1.8V to +5.5V. Exceeding +6V risks permanent damage due to internal diode clamp stress, as specified in the Absolute Maximum Ratings table. Operation at +5.5V yields optimal RON (25Ω typ) and dynamic performance, while maintaining full 1.8V logic compatibility.
Does MAX4695ETC+TGC1 support bidirectional analog signal flow?
Yes, MAX4695ETC+TGC1 supports fully bidirectional analog signal routing on all COM_, NO_, and NC_ pins. The device contains passive CMOS transmission gates with symmetrical on-resistance characteristics, allowing signals to pass from COM to NO/NC or vice versa without polarity constraints. This enables flexible use in both source-selection and load-switching configurations within the same design.
What is the guaranteed on-resistance matching between channels for MAX4695ETC+TGC1?
MAX4695ETC+TGC1 guarantees on-resistance matching (ΔRON) of ≤3Ω maximum at +2.7V supply and +25°C, defined as the difference between the highest and lowest RON values measured across both SPDT channels under identical conditions. This tight matching ensures consistent gain and phase response in differential or parallel signal paths, critical for instrumentation and balanced audio applications.
Can MAX4695ETC+TGC1 operate with 1.8V logic inputs when powered from a 5V supply?
No - MAX4695ETC+TGC1 logic thresholds scale with V+. At +5V supply, VIH is +2.0V minimum and VIL is +0.8V maximum, making it TTL-compatible but not 1.8V-logic compatible. True 1.8V logic compatibility is only guaranteed when V+ is between +2.7V and +3.3V, where VIH = +1.4V and VIL = +0.5V. Using 1.8V logic signals with V+ = +5V may result in unreliable switching.
What thermal considerations apply to the MAX4695ETC+TGC1 12-pin TQFN package?
The MAX4695ETC+TGC1 TQFN package features an exposed thermal pad that must be soldered to a PCB copper pour for effective heat dissipation. With a derating factor of 16.7mW/°C above +70°C, the package supports up to 1333.3mW continuous power dissipation at +70°C ambient. Proper thermal land design per JEDEC MO-220 standards is required to maintain junction temperature within the -40°C to +85°C operating range during sustained switching.
