Product details
Overview
MAX4693EBE+T from Maxim Integrated is a triple single-pole/double-throw (SPDT) analog switch IC designed for bidirectional rail-to-rail signal routing in low-voltage systems. It operates from single +2V to +11V or dual ±2V to ±5.5V supplies, delivers 25Ω max on-resistance at ±4.5V, guarantees break-before-make switching, and supports 1.8V logic compatibility at +3V supply - ideal for battery-powered audio/video multiplexing in cellular handsets.
For engineers reviewing the MAX4693EBE+T datasheet, MAX4693EBE+T pinout, MAX4693EBE+T application, or MAX4693EBE+T equivalent, this page provides verified electrical specs, UCSP package layout, real-world use scenarios, and two validated alternative SPDT switch options for space-constrained portable designs.
Technical Context
The MAX4693EBE+T implements three independent CMOS SPDT switches with separate digital control inputs (A, B, C), each driving one switch pair (X, Y, Z). Its internal architecture uses matched P- and N-channel MOSFETs to achieve rail-to-rail analog conduction and guaranteed break-before-make timing of ≤2ns.
It supports both unipolar and bipolar operation: V− connects to GND for single-supply use or to negative rail for ± supplies; analog signal range spans V− to V+, and all digital inputs are level-shifted internally to drive gate voltages across the full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches (X, Y, Z), each with dedicated control input (A/B/C) |
| Supply Range | +2V to +11V single supply or ±2V to ±5.5V dual supply - enables flexible power architecture in mixed-signal systems |
| On-Resistance (max) | 25Ω at ±4.5V - ensures minimal signal attenuation and distortion in audio paths up to 20kHz |
| On-Resistance Matching | 3Ω max between channels at ±4.5V - critical for balanced differential signal routing and channel-to-channel consistency |
| Leakage Current (max) | ±20nA at +85°C - preserves signal integrity in high-impedance sensor or bias networks |
| Break-Before-Make Time | ≤2ns - prevents momentary short-circuit during switching, essential for glitch-free audio/video source selection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4693EGE+ | Same die, 16-pin QFN-EP package (4mm × 4mm); exposed pad requires thermal anchoring | Better thermal dissipation but 4× larger PCB footprint than UCSP; suited for industrial temperature test fixtures | Select when thermal management outweighs size constraints and reflow profile supports exposed-pad soldering |

FAQ
What supply voltages does the MAX4693EBE+T support?
The MAX4693EBE+T operates from 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 guaranteed break-before-make timing. The device maintains rail-to-rail analog signal handling across the full supply range, and its digital inputs are 1.8V logic-compatible at +3V supply.
How is the MAX4693EBE+T pinout configured for SPDT operation?
The MAX4693EBE+T features three independent SPDT switches: X (controlled by pin C4/A), Y (controlled by D4/B), and Z (controlled by D3/C). Each has dedicated normally closed (e.g., A1/X0) and normally open (e.g., B1/X1) inputs, plus a common terminal (e.g., A2/X). Pin C2 (EN) globally disables all switches when high. V+ (C3) and V− (B2) set analog signal bounds; GND (B3) serves as digital reference.
Does the MAX4693EBE+T support rail-to-rail analog signals?
Yes, the MAX4693EBE+T supports true rail-to-rail analog signal handling from V− to V+. When operated from ±5V supplies, signals can swing from -5V to +5V; under single +5V supply (V− = GND), signals span 0V to +5V. This capability is enabled by internal level-shifting circuitry that drives switch gates across the full supply range, preserving signal integrity without external biasing.
What is the leakage current specification for the MAX4693EBE+T at elevated temperature?
The MAX4693EBE+T guarantees ±20nA maximum off-leakage current (IW(OFF), IX(OFF), IY(OFF), IZ(OFF)) over the full operating temperature range of -40°C to +85°C, with typical values of ±2nA at +25°C. This low leakage ensures minimal error in high-impedance sensor interfaces and precision bias networks, even in thermally demanding environments like enclosed handheld devices.
Is the MAX4693EBE+T compatible with 1.8V logic control signals?
Yes, the MAX4693EBE+T supports 1.8V logic-compatible digital inputs when powered from a +3V supply - VIH is guaranteed ≥1.4V and VIL ≤0.4V. This allows direct interfacing with modern low-voltage microcontrollers and FPGAs without level-shifting circuitry, reducing BOM count and layout complexity in battery-operated systems.
