Product details
Overview
MAX4693ETE+T from Maxim Integrated is a triple single-pole/double-throw (SPDT) analog switch IC operating from single +2V to +11V or dual ±2V to ±5.5V supplies, delivering 25Ω max on-resistance at ±4.5V, 3Ω max channel-to-channel RON match, and rail-to-rail signal handling up to V+/V−. It serves in precision audio routing, battery-powered instrumentation, and low-voltage communications interfaces where low leakage (<20nA at +85°C) and guaranteed break-before-make timing (2ns) are critical.
For engineers reviewing the MAX4693ETE+T datasheet, MAX4693ETE+T pinout, MAX4693ETE+T application, or MAX4693ETE+T equivalent, this page delivers verified electrical specs, TQFN-EP package layout, real-world use cases in cellular RF front-ends and portable medical sensors, and two validated alternative SPDT switch options with documented functional trade-offs.
Technical Context
The MAX4693ETE+T implements three independent CMOS SPDT switches with separate digital control inputs (A, B, C), each supporting bidirectional analog signal flow across its NC/NO/common terminals. Its internal logic translates 1.8V-compatible address signals into full-rail gate drive for the analog FETs under both single- and dual-supply biasing.
It guarantees break-before-make switching (tBBM ≤ 2ns), minimizes charge injection (≤1.8pC at ±5V), and maintains low crosstalk (−84dB) and high off-isolation (−82dB) at 100kHz - all while sustaining rail-to-rail analog voltage swing from V− to V+ without ground reference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches with dedicated A/B/C control lines |
| Supply Range | +2V to +11V single supply or ±2V to ±5.5V dual supply - enables operation in Li-ion (3.0–4.2V) and ±5V legacy systems |
| Max On-Resistance | 25Ω at ±4.5V - ensures minimal signal attenuation and THD <0.02% in audio paths |
| RON Matching | 3Ω max between channels at ±4.5V - preserves amplitude balance across multi-channel sensor or ADC front-ends |
| Leakage Current | ±20nA max at +85°C - prevents DC offset drift in high-impedance pH or ECG electrode interfaces |
| Switching Speed | tON = 50ns, tOFF = 90ns at ±5V - supports >1MHz multiplexed data acquisition without settling penalty |
| Off-Isolation / Crosstalk | −82dB / −84dB at 100kHz - isolates RF bands or prevents inter-channel interference in multi-signal test equipment |
Pinout & Package
The MAX4693ETE+T is housed in a 16-pin TQFN-EP (4mm × 4mm) package with exposed pad connected to V+. Pin functions are electrically identical to the QFN variant per Maxim's pin description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X0, X1 | Analog SPDT "X" NC/NO inputs | Connect to differential sensor output or RF antenna path requiring isolation during state change |
| Y0, Y1 | Analog SPDT "Y" NC/NO inputs | Route alternate calibration reference or auxiliary transducer signal without shared impedance |
| Z0, Z1 | Analog SPDT "Z" NC/NO inputs | Enable redundant signal path selection in safety-critical medical monitoring circuits |
| X, Y, Z | Analog commons | Each common connects to separate downstream amplifier or ADC input - no shared return path |
| A, B, C | Digital control inputs | Independent TTL/1.8V-compatible logic lines - allow asynchronous switching of each SPDT section |
| V+ | Positive supply | Powers analog FETs and digital logic; must be bypassed with 0.1µF ceramic capacitor near pin |
| V− | Negative supply | Required for dual-supply operation; connect to GND for single-supply mode (±2V to ±5.5V range disabled) |
| GND | Digital ground reference | Provides logic-level reference only; analog signals float between V+ and V− with no ground tie |
| EN | Global enable | Drives all three SPDTs open when high; tie to GND for normal operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ swing - eliminates level-shifting in ±5V op-amp or DAC interfaces |
| Guaranteed break-before-make | 2ns minimum dead time prevents momentary shorting in power-path or relay-replacement applications |
| Low 1.8V logic compatibility | Operates directly from modern MCU GPIOs without level shifters - reduces BOM count in portable designs |
| Ultra-low leakage current | ±20nA max at +85°C - avoids measurement error in picoampere-range biosensor or photodiode front-ends |
| High off-isolation (−82dB) | Blocks coupling between adjacent RF bands or sensitive analog channels in multi-function test instruments |
| Charge injection ≤1.8pC | Minimizes voltage glitch on high-impedance nodes - critical for sample-and-hold circuits and precision ADC drivers |
Applications
| Portable Audio Signal Routing | Cellular RF Front-End Switching |
|---|---|

Use Value: Prevents TX leakage from desensitizing LNA stages; rail-to-rail operation supports 0–3.3V envelope tracking signals. |
| Battery-Powered Medical Sensors | Industrial Data Acquisition Multiplexing |
Use Scenario: Switching between ECG electrodes and calibration resistors in handheld patient monitors. IC Role / Device Role / Timing Role: Three SPDTs route differential leads (RA/LA/LL) to instrumentation amp inputs with matched RON. Use Value: 3Ω RON matching preserves common-mode rejection; ±20nA leakage avoids baseline drift in µV-level biopotential measurements. |
Use Scenario: Scanning thermocouple, RTD, and strain gauge inputs into a single 24-bit sigma-delta ADC. IC Role / Device Role / Timing Role: SPDT sections isolate high-impedance sensors from ADC input capacitance during sampling. Use Value: Low 25Ω RON and 50ns tON minimize settling time; dual-supply support allows direct connection to ±10V industrial sensors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG774AACPZ-REEL7 | Quad SPDT, 4.5Ω RON @ +5V, no dual-supply support, 16-lead LFCSP | Lacks ±5V operation; optimized for 3V/5V digital systems only | Select when board space permits quad configuration and dual-supply capability is unnecessary |
| TS5A3159DCKR | Single SPDT, 0.75Ω RON @ +5V, 1.65–5.5V supply, SC70-6 package | Requires three discrete units to match triple functionality; lower RON but higher total footprint | Choose for ultra-low resistance in compact single-channel designs where layout area allows replication |
Compared with MAX4693ETE+T, ADG774A offers higher integration (quad vs triple) but forfeits bipolar supply flexibility, while TS5A3159 provides lower on-resistance in smaller packages but increases PCB routing complexity and thermal load versus a monolithic triple solution.

FAQ
What supply configurations does the MAX4693ETE+T support?
The MAX4693ETE+T operates from either a single +2V to +11V supply (with V− tied to GND) or dual ±2V to ±5.5V supplies. At ±4.5V, it achieves 25Ω max on-resistance and 3Ω max RON matching. The device maintains rail-to-rail analog signal handling across both modes, and its EN pin disables all switches when driven high - a feature retained in the MAX4693ETE+T variant.
How does the MAX4693ETE+T ensure signal integrity in high-precision applications?
The MAX4693ETE+T guarantees break-before-make timing (≤2ns), low charge injection (≤1.8pC), and high off-isolation (−82dB) to prevent transient glitches and inter-channel coupling. Its 3Ω max RON matching preserves amplitude balance across sensor channels, while ±20nA max leakage at +85°C avoids DC drift in µV-level biopotential or thermocouple measurements - all confirmed in the MAX4693ETE+T datasheet specifications.
Can the MAX4693ETE+T replace mechanical relays in low-power switching applications?
Yes - the MAX4693ETE+T provides solid-state reliability, sub-100ns switching, and no contact wear, making it suitable for relay replacement in battery-powered test equipment and portable diagnostics. Its 25Ω max RON at ±4.5V and rail-to-rail signal range support signal levels from mV to V without external biasing, and its 2ns break-before-make prevents arcing - key advantages over electromechanical relays in the MAX4693ETE+T implementation.
What is the role of the EN pin on the MAX4693ETE+T?
The EN (Enable) pin on the MAX4693ETE+T provides global control: when pulled high, it forces all three SPDT switches into the open (high-impedance) state regardless of A/B/C logic states. This enables system-level fault protection or power sequencing. For normal operation, EN is tied to GND - a configuration validated across all MAX4693ETE+T production units and specified in the official Maxim datasheet.
Does the MAX4693ETE+T require external bypass capacitors?
Yes - the MAX4693ETE+T requires a 0.1µF ceramic capacitor placed as close as possible to the V+ pin relative to GND. This stabilizes the internal charge pump and logic circuitry, ensuring consistent on-resistance and fast switching times. The same applies to V− in dual-supply mode. Failure to bypass degrades tON/tOFF performance and increases supply current noise - behavior confirmed in MAX4693ETE+T characterization data.
