Product details
Overview
The MAX4695ETC+ 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 precision audio/video routing in battery-powered systems.
For engineers reviewing the MAX4695ETC+ datasheet, MAX4695ETC+ pinout, MAX4695ETC+ application, or MAX4695ETC+ 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 at +2.7V to +3.3V supplies.
Technical Context
The MAX4695ETC+ implements two independent CMOS SPDT switches with break-before-make switching action, ensuring no signal shorting during state transitions. Its channel-matched RON (≤3Ω max) and flatness (≤10Ω max) enable high-fidelity signal routing across the full 0V to V+ analog range.
Designed for low-voltage portable systems, it supports 1.8V logic thresholds (VIL = 0.5V, VIH = 1.4V at +3V supply) and delivers >300MHz -3dB bandwidth with only 4pC charge injection-critical for sample-and-hold and data-acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply-enables direct integration into Li-ion (3.0–3.7V) and USB-powered (5V) systems without level-shifting. |
| On-Resistance (RON) | 60Ω(max) at +2.7V supply-ensures minimal signal attenuation and gain error in sensor/ADC interface paths. |
| RON Matching | 3Ω(max) between channels-preserves amplitude balance in differential or stereo signal paths. |
| Turn-On / Turn-Off Time | tON = 30ns, tOFF = 18ns at +3V-supports high-speed multiplexing in digital audio and serial data routing. |
| Crosstalk | -82dB at 1MHz-prevents audible interference between adjacent audio channels or RF/data lines. |
| Charge Injection | 4pC-limits voltage glitch on sampled nodes, critical for 12-bit+ ADC front-ends and precision DAC outputs. |
| Off-Isolation | -75dB at 1MHz-maintains signal integrity when unused channels are disconnected in multi-source systems. |
Pinout & Package
MAX4695ETC+ is housed in a 3mm × 3mm, 12-pin Thin QFN package with exposed thermal pad (TQFN-12), optimized for space-constrained portable designs and thermal performance in continuous switching operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | CMOS-compatible logic inputs controlling Switch 1 and Switch 2 independently; accept 1.8V logic levels at +2.7V to +3.3V supply. |
| COM1, COM2 | Analog common terminals | Bidirectional signal ports-connect to source or load; support rail-to-rail analog signals (0V to V+). |
| NO1, NO2 | Normally open analog terminals | Connect to COMx when corresponding INx = high; used for active-path routing in SPDT configuration. |
| NC1, NC2 | Normally closed analog terminals | Connect to COMx when corresponding INx = low; provide default-path continuity during power-up or logic low states. |
| V+ | Positive supply input | Single supply rail (+1.8V to +5.5V); powers internal switch circuitry and defines analog signal ceiling. |
| GND | Ground reference | Return path for supply current and analog signal reference; must be low-impedance for THD < 0.03%. |
| Pins 6 & 10 | No connection (N.C.) | Unbonded die pads-must remain unconnected on PCB; no electrical function or thermal role. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without clipping-enables direct interfacing with op-amps, ADCs, and DACs operating at full supply swing. |
| Break-before-make switching | Guaranteed ≤2ns tBBM prevents momentary shorting between NOx and NCx-essential for avoiding signal corruption in relay-replacement applications. |
| Low THD (0.03%) | Minimizes harmonic distortion in audio paths-meets fidelity requirements for MP3 players and cellular phone handsets. |
| 1.8V logic compatibility | Operates with core logic voltages down to 1.8V-eliminates need for external level shifters in modern ultra-low-power SoC interfaces. |
| High off-isolation (-75dB) | Blocks leakage between active and inactive channels-critical for maintaining SNR in multi-channel data acquisition and 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 |
|---|---|---|---|
| ADG726BRUZ | Higher RON (85Ω max at +3V), slower tON/tOFF (45ns/35ns), no guaranteed RON matching spec | Less suitable for precision audio or matched-channel instrumentation where RON tracking is critical | Prefer MAX4695ETC+ when RON matching ≤3Ω and tBBM ≤2ns are required. |
| TS5A23157DCUR | Lower supply range (1.65V–5.5V), higher RON (120Ω max at +3V), no specified charge injection or THD | Acceptable for general-purpose I/O switching but not for high-fidelity audio or precision data acquisition | Choose MAX4695ETC+ for applications demanding ≤4pC charge injection and 0.03% THD in battery-operated gear. |
Compared with ADG726BRUZ and TS5A23157DCUR, the MAX4695ETC+ uniquely combines guaranteed RON matching, sub-2ns break-before-make timing, and industry-leading THD-making it the preferred choice for high-integrity portable signal routing where parameter consistency directly impacts system accuracy.

FAQ
What is the maximum supply voltage rating for the MAX4695ETC+?
The MAX4695ETC+ has an absolute maximum supply voltage (V+) of +6V, but its operational range is strictly +1.8V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. For reliable long-term operation, maintain V+ within the specified 1.8V–5.5V window-especially critical in battery-fed systems where voltage spikes may occur during charging cycles. The MAX4695ETC+'s internal protection diodes clamp signals beyond V+ or GND, but only if forward current remains below 20mA.
Does the MAX4695ETC+ support rail-to-rail analog signal switching?
Yes, the MAX4695ETC+ fully supports rail-to-rail analog signal handling: analog voltages from GND to V+ pass through the switch with minimal RON variation. This is confirmed by test data showing RON flatness ≤10Ω over the full 0V to V+ range at +2.7V supply. The device's bidirectional architecture allows COM_, NO_, and NC_ pins to serve as either input or output-enabling flexible signal flow in audio, sensor, and data-path applications without external biasing. The MAX4695ETC+ maintains this capability across its entire operating temperature range (-40°C to +85°C).
What is the guaranteed on-resistance matching between channels for the MAX4695ETC+?
The MAX4695ETC+ guarantees on-resistance matching (∆RON) of ≤3Ω maximum at +2.7V supply and +25°C, defined as RON(max) − RON(min) across both SPDT switches. This specification holds over the full industrial temperature range (-40°C to +85°C) and is 100% tested at +85°C. Tight matching ensures amplitude consistency in stereo audio paths, differential sensor interfaces, or any application where relative signal gain between channels must remain stable. The MAX4695ETC+ achieves this via matched FET design and process-controlled threshold tracking-distinct from typical analog switches that only specify typical matching.
Can the MAX4695ETC+ operate with 1.8V logic inputs while powered from a 2.7V supply?
Yes-the MAX4695ETC+ is explicitly designed for 1.8V logic compatibility when V+ is between +2.7V and +3.3V. Its input logic thresholds are VIL = +0.5V (max) and VIH = +1.4V (min) under those conditions, allowing direct interfacing with 1.8V-core microcontrollers and baseband processors without level shifters. Input leakage remains ≤±1µA across temperature, preserving drive strength. This feature is validated in the Electrical Characteristics table for +3V supply and is integral to the MAX4695ETC+'s role in ultra-low-power portable systems where mixed-voltage domain interoperability is essential.
What is the charge injection specification for the MAX4695ETC+, and why does it matter?
The MAX4695ETC+ specifies 4pC maximum charge injection-measured with VGEN = 0V, RGEN = 0Ω, and CL = 1.0nF. This low value minimizes voltage glitches on high-impedance nodes (e.g., sample-and-hold capacitors or DAC output filters), preventing errors in precision data acquisition and audio reconstruction. In practice, 4pC translates to <1mV step error on a 4.7nF hold capacitor-a key requirement for 12-bit+ resolution systems. The MAX4695ETC+ achieves this via balanced switch architecture and careful layout, distinguishing it from alternatives with ≥8pC injection that degrade dynamic performance.
