Product details
Overview
The MAX4693EGE+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. It serves as a precision signal routing device in low-voltage portable audio and communications circuits.
For engineers reviewing the MAX4693EGE+T datasheet, MAX4693EGE+T pinout, MAX4693EGE+T application, or MAX4693EGE+T equivalent, key selection criteria include guaranteed break-before-make timing (2ns), low 1nA leakage at +85°C, 16-pin QFN-EP package with exposed pad, and compatibility with 1.8V logic at +3V supply.
Technical Context
The MAX4693EGE+T implements three independent SPDT switches, each controlled by dedicated digital inputs (A, B, C), enabling simultaneous but isolated switching of three analog paths. Its CMOS architecture supports bidirectional signal flow and rail-to-rail operation across the full analog supply range.
It features internal logic-level translators that convert 1.8V/3V/5V-compatible digital inputs into full V+/V− gate drive signals, decoupling logic and analog domains. Break-before-make timing is guaranteed at ≤2ns to prevent signal shorting during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Single +2V to +11V or dual ±2V to ±5.5V - enables flexible power architecture in battery-powered and bipolar systems |
| On-Resistance (RON) | 25Ω max at ±4.5V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match | 3Ω max between channels at ±4.5V - critical for matched gain/phase in multi-channel instrumentation |
| Leakage Current | ±20nA max at +85°C - preserves DC accuracy in high-impedance sensor interfaces |
| Break-Before-Make | 2ns max - prevents momentary short-circuiting of analog sources during switching |
| Switching Time (tON/tOFF) | 35ns/60ns typ at +5V - supports audio-band and moderate-speed data routing |
| Logic Compatibility | 1.8V logic at +3V supply; TTL at +5V - simplifies interface with mixed-voltage microcontrollers |
Pinout & Package
The MAX4693EGE+T is housed in a 16-pin QFN-EP (4mm × 4mm) package with exposed thermal pad connected to V+. Pin functions are validated per Maxim's official datasheet revision 6 (2012).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switches and internal logic; must be bypassed with 0.1µF capacitor |
| V- | Negative supply input | Required for dual-supply operation; connect to GND for single-supply use |
| GND | Digital ground reference | Reference for logic inputs only; analog signals are referenced solely to V+/V− |
| EN | Enable control | Active-high; drives all three SPDTs open when high - provides global shutdown |
| A, B, C | Digital control inputs | Independent control of X, Y, Z SPDTs respectively - no shared address decoding |
| X, Y, Z | Common terminals | Bidirectional analog nodes connecting to NC/NO paths - define signal routing center points |
| X0/X1, Y0/Y1, Z0/Z1 | SPDT switch terminals | Normally closed (X0/Y0/Z0) and normally open (X1/Y1/Z1) paths - support fail-safe or default-state designs |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full dynamic range in audio and sensor front-ends |
| Guaranteed break-before-make | 2ns maximum transition gap prevents cross-conduction - eliminates risk of source shorting in power-sensitive circuits |
| Low 1nA leakage at +85°C | Minimizes error in high-impedance measurement paths (e.g., pH sensors, photodiode amps) |
| 16-pin QFN-EP with exposed pad | Enables efficient thermal dissipation and compact layout - critical for space-constrained handheld devices |
| 1.8V logic compatibility at +3V supply | Direct interfacing with ultra-low-power MCUs (e.g., ARM Cortex-M0+) without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4693ETE+T | 16-pin TQFN-EP package (4mm × 4mm); identical electrical specs and pinout | Slightly higher thermal resistance vs. QFN-EP; same PCB footprint but different solder profile | Select for legacy TQFN assembly lines or where enhanced mechanical robustness is prioritized |
| ADG774AARUZ | Quad SPDT, 16-pin TSSOP; 4.5Ω RON at +5V; no dual-supply support; 3.5ns tBBM | Limited to single +2.7V to +5.5V operation; higher RON and slower break-before-make | Choose when quad-channel count is required and bipolar supply is unnecessary |
Compared with MAX4693ETE+T, the MAX4693EGE+T offers lower thermal resistance via its QFN-EP exposed pad; versus ADG774AARUZ, it delivers superior dual-supply flexibility, lower RON, and faster break-before-make-critical for precision bipolar signal routing.

FAQ
What supply configurations does the MAX4693EGE+T support?
The MAX4693EGE+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 requires proper supply bypassing (0.1µF ceramic capacitor at V+) and observes strict sequencing: V+ first, then V−, then logic inputs.
How is the MAX4693EGE+T pinout structured for triple SPDT control?
The MAX4693EGE+T uses dedicated digital inputs A, B, and C to independently control its three SPDT switches (X, Y, Z). Each SPDT has a common terminal (X, Y, Z) and two switched paths (X0/X1, Y0/Y1, Z0/Z1). EN provides global enable/disable. Pin mapping is fixed per Maxim's datasheet: pins 1,3,4,8,9,11,12,15,16 serve as analog I/O; pins 2 (GND), 6 (V+), 10 (EN), 13 (X), 14 (V−) handle power/control.
Does the MAX4693EGE+T guarantee break-before-make timing, and why does it matter?
Yes, the MAX4693EGE+T guarantees ≤2ns break-before-make timing. This ensures the normally closed (NC) path opens before the normally open (NO) path closes, preventing momentary short-circuits between analog sources. In audio or sensor applications, this eliminates audible pops, measurement glitches, or damage to upstream drivers caused by unintended current flow.
What is the leakage performance of the MAX4693EGE+T over temperature?
The MAX4693EGE+T specifies ±20nA max off-leakage current at +85°C and ±2nA typical at +25°C. On-state leakage is also ±20nA max at +85°C. This low leakage preserves DC accuracy in high-impedance circuits (e.g., medical sensors or precision thermistor networks), where even nanoampere errors translate to significant voltage offsets.
Can the MAX4693EGE+T interface directly with 1.8V logic systems?
Yes, the MAX4693EGE+T supports 1.8V logic-compatible inputs when operated from a +3V supply - VIH = +1.4V min and VIL = +0.4V max are met. This allows direct connection to low-voltage microcontrollers (e.g., STM32L series) without external level shifters, reducing BOM cost and board area in battery-powered designs.
