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 portable electronics.
For engineers reviewing the MAX4695EGC-T datasheet, MAX4695EGC-T pinout, MAX4695EGC-T application, or MAX4695EGC-T equivalent, this page provides verified electrical parameters, TQFN-12 pin mapping, break-before-make timing, leakage performance, and RoHS-compliant sourcing status - all confirmed against Maxim's official 2005 datasheet and package documentation.
Technical Context
The MAX4695EGC-T integrates two independent SPDT switches with guaranteed break-before-make action (tBBM ≤ 2ns), enabling glitch-free signal path selection in bidirectional analog circuits. Its 1.8V-logic-compatible digital inputs support direct interfacing with low-voltage microcontrollers without level-shifting.
Designed for signal integrity in battery-powered systems, it maintains <10Ω RON flatness over full analog range (0V to V+), −82dB crosstalk at 1MHz, and 0.03% THD at 2Vp-p, ensuring minimal distortion in audio and data-acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct use with Li-ion, 3.3V, and 5V rails without auxiliary regulators. |
| On-Resistance (max) | 60Ω at +2.7V - ensures minimal insertion loss and voltage drop in low-level sensor or audio signal paths. |
| RON Matching (max) | 3Ω between channels - critical for matched gain/attenuation in differential or dual-path routing applications. |
| Turn-On / Turn-Off Time | 30ns / 18ns at +3V - supports high-speed multiplexing in data acquisition and communication switching. |
| Off-Isolation | −75dB at 1MHz - suppresses coupling between inactive and active signal paths in multi-channel systems. |
| Crosstalk | −82dB at 1MHz - prevents interference between adjacent switched audio or video signals. |
| Charge Injection | 4pC - minimizes transient glitches during switching, essential for precision ADC front-ends. |
Pinout & Package
MAX4695EGC-T is housed in a 12-pin Thin QFN (3mm × 3mm × 0.9mm) with exposed thermal pad. Pin numbering follows JEDEC MO-220 standard; Pin 1 is marked by corner chamfer per drawing 21-0102G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Digital control input for Switch 1 | Active-high logic input; accepts 1.8V CMOS levels when V+ = +2.7V to +3.3V. |
| 2 (NO1) | Normally open terminal, Switch 1 | Connects to COM1 only when IN1 = high; bidirectional analog path. |
| 3 (GND) | Ground reference | Primary return path for analog and digital currents; must be low-impedance. |
| 4 (NO2) | Normally open terminal, Switch 2 | Independent analog path routed by IN2; electrically isolated from Switch 1. |
| 5 (IN2) | Digital control input for Switch 2 | Independent enable for second SPDT; no internal coupling to IN1. |
| 6 (COM2) | Common terminal, Switch 2 | Central analog node for Switch 2; connects to NO2 or NC2 based on IN2 state. |
| 7 (NC2) | Normally closed terminal, Switch 2 | Connected to COM2 when IN2 = low; breaks before make occurs at IN2 transition. |
| 8 (V+) | Positive supply input | Single power rail for analog and digital sections; absolute max = +6V. |
| 9 (NC1) | Normally closed terminal, Switch 1 | Connected to COM1 when IN1 = low; complements NO1 in SPDT configuration. |
| 10 (COM1) | Common terminal, Switch 1 | Analog I/O port shared between NO1 and NC1; supports rail-to-rail signal swing. |
| 11 (N.C.) | No connection | Internally unconnected; must remain floating or grounded per layout best practice. |
| 12 (N.C.) | No connection | Internally unconnected; no electrical function; avoid routing traces to these pins. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input range without clipping - preserves full dynamic range in audio and sensor interfaces. |
| Break-before-make switching | tBBM ≤ 2ns guarantees no momentary short between NO and NC terminals - prevents signal contention in relay-replacement designs. |
| Low charge injection (4pC) | Reduces voltage transients on high-impedance nodes - critical for sample-and-hold and precision multiplexer applications. |
| −3dB bandwidth >300MHz | Enables clean switching of video signals (e.g., composite, S-video) and high-speed data streams up to ~100Mbps. |
| 1.8V logic compatibility | Direct interface with modern ultra-low-voltage MCUs and FPGAs - eliminates external level shifters in portable designs. |

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 |
|---|---|---|---|
| MAX4695ETC | Same die, identical electrical specs, but packaged in 12-pin Thin QFN (3×3×0.8mm) with RoHS-compliant lead finish. | Suitable for new designs requiring lead-free compliance; same thermal and electrical performance as MAX4695EGC-T. | Select MAX4695ETC for RoHS-mandated production; MAX4695EGC-T remains valid for legacy or non-RoHS programs. |
| ADG726BRUZ | 60Ω RON at +3V, but tON/tOFF = 12ns/8ns; uses 24-pin TSSOP; higher supply current (1µA vs. <1µA). | Better speed for high-frequency multiplexing, but larger footprint and no 1.8V logic compatibility. | Choose ADG726BRUZ only if sub-15ns switching is required and board space allows 24-pin TSSOP; otherwise MAX4695EGC-T offers superior integration. |
Compared with MAX4695ETC, MAX4695EGC-T shares identical functionality but differs in RoHS status and mechanical thickness (0.9mm vs. 0.8mm); versus ADG726BRUZ, it trades raw speed for smaller size, lower voltage operation, and tighter RON matching - making it optimal for portable, low-power, space-constrained analog routing.

FAQ
What is the maximum supply voltage rating for MAX4695EGC-T?
The absolute maximum supply voltage (V+) for MAX4695EGC-T is +6V. Operation beyond this limit risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V; at +5.5V, on-resistance drops to 40Ω max and switching times improve to 25ns/15ns. Always observe proper power-supply sequencing - apply V+ before analog signals - to prevent latch-up or overstress.
Does MAX4695EGC-T support rail-to-rail analog signal switching?
Yes, MAX4695EGC-T supports true rail-to-rail analog signal handling: analog inputs and outputs can swing from GND to V+ without clipping or increased distortion. This is confirmed in the Electrical Characteristics table (Analog Signal Range = 0V to V+) and Typical Operating Characteristics (RON vs. VCOM curves show stable resistance across full range). It enables full utilization of ADC/DAC dynamic range in portable systems.
What is the guaranteed on-resistance matching between the two switches in MAX4695EGC-T?
MAX4695EGC-T guarantees ≤3Ω maximum on-resistance matching (∆RON) between its two SPDT switches when powered from +2.7V and measured at ICOM = 1mA. This specification is tested across temperature (−40°C to +85°C) and ensures consistent gain or attenuation in dual-path applications like stereo audio routing or differential sensor multiplexing.
Is MAX4695EGC-T pin-compatible with other variants in the MAX4695 family?
Yes, MAX4695EGC-T shares identical pinout and footprint with MAX4695ETC, MAX4695EUB, and all other MAX4695 variants - all use the same 12-pin TQFN or 10-pin µMAX layouts defined in Maxim's datasheet. However, MAX4695EGC-T and MAX4695ETC both use the 12-pin TQFN package (though differing in thickness and RoHS status), while MAX4695EUB uses the 10-pin µMAX. Verify package drawings (21-0102G vs. 21-0136I) before layout reuse.
What is the typical charge injection value for MAX4695EGC-T, and why does it matter?
MAX4695EGC-T specifies 4pC maximum charge injection (Q), measured with VGEN = 0, RGEN = 0, and CL = 1.0nF. This low value minimizes voltage glitches on high-impedance nodes (e.g., sample-and-hold capacitors or sensor bias networks), preventing errors in precision data acquisition. At 4pC into 1nF, step error is just 4mV - well below 12-bit LSB thresholds.
