Product details
Overview
MAX4694EBE from Maxim Integrated is a quad single-pole/double-throw (SPDT) analog switch IC in a 16-bump UCSP package (2mm × 2mm), operating from a single +2V to +11V supply. It delivers rail-to-rail signal handling, 35Ω max on-resistance at +5V, <5Ω channel-to-channel on-resistance match, and 1nA typical leakage current - enabling precision signal routing in space-constrained portable audio and battery-powered communication circuits.
For engineers reviewing the MAX4694EBE datasheet, MAX4694EBE pinout, MAX4694EBE application, or MAX4694EBE equivalent, this page provides verified electrical specifications, UCSP package layout, break-before-make timing assurance, low-crosstalk (-87dB @ 100kHz) performance, and direct alternatives for SPDT switching in low-voltage embedded systems.
Technical Context
The MAX4694EBE implements four independent bidirectional SPDT switches with shared digital control: input A selects W/Y paths, input B selects X/Z paths. It lacks V− and EN pins - unlike MAX4691–MAX4693 - confirming its single-supply-only architecture with GND as reference.
All switches feature guaranteed break-before-make operation (≥2ns), 90ns typical transition time, and logic-level compatibility: 1.8V-compatible at +3V supply, TTL-compatible at +5V supply. Analog signal range spans rail-to-rail (0V to V+), with no negative supply required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Four independent SPDT switches (W, X, Y, Z), each with NC/NO paths and common terminal |
| Supply Range | +2V to +11V single supply only - no dual ±V operation; GND used as return |
| On-Resistance (max) | 35Ω at +5V supply - ensures minimal signal attenuation in audio and sensor paths |
| On-Resistance Match | 5Ω max between channels at +2.7V - critical for matched gain or differential signal integrity |
| Leakage Current (max) | 20nA at +85°C - preserves accuracy in high-impedance sensor or bias networks |
| Off-Isolation | -80dB at 0.1MHz - suppresses crosstalk between inactive signal paths |
| Transition Time | 90ns typical - supports fast multiplexing in data acquisition and modem front-ends |
Pinout & Package
MAX4694EBE uses a 16-bump UCSP (Ultra-Chip Scale Package) measuring 2mm × 2mm with 0.5mm pitch. The package has no exposed pad (EP) - unlike QFN variants - and requires JEDEC J-STD-020A IR/VPR reflow profile per Maxim's UCSP reliability notice.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| W0, W1, X0, X1, Y0, Y1, Z0, Z1 | Analog switch NC/NO terminals | Eight dedicated signal endpoints - W0/W1 form first SPDT pair; X/Y/Z follow same topology |
| W, X, Y, Z | Analog common terminals | Four bidirectional switch outputs - each connects to one NC/NO pair based on control inputs |
| A, B | Digital control inputs | A controls W/Y switches; B controls X/Z switches - no enable or address decoding logic |
| GND | Ground reference | Return path for digital logic and analog substrate - must be low-impedance for leakage control |
| V+ | Positive supply | Powers analog switches and internal logic - bypass with 0.1µF capacitor near pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full 0V to V+ voltage swing - enables direct interfacing with op-amps and ADCs without level-shifting |
| Guaranteed break-before-make | ≥2ns minimum dead time prevents momentary shorting during state transitions - essential for power domain isolation |
| Low 1nA typical leakage | Minimizes error in high-Z sensor nodes (e.g., pH electrodes, piezoresistive bridges) across temperature |
| 1.8V logic compatibility | Operates with modern ultra-low-power microcontrollers (e.g., ARM Cortex-M0+) at +3V supply without level shifters |
| UCSP footprint reduction | 2mm × 2mm area - saves >70% board space vs. 4mm × 4mm QFN, critical for cellular phone RF modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4694EGE | Same die in 16-pin QFN-EP (4mm × 4mm); includes exposed pad tied to V+ | Higher thermal dissipation (1481mW vs. 659mW), easier rework, but 4× larger footprint | Select when thermal management > space constraints, or when JEDEC-compliant reflow is unavailable for UCSP |
| TMUX1574RTER | TI quad SPDT with 3.5Ω RON match, 0.5pC charge injection, but requires ≥1.08V logic and no UCSP option | Superior matching and lower charge injection, yet incompatible with 1.8V logic at 3V supply | Prefer for precision instrumentation where leakage and distortion dominate; avoid in 1.8V logic ecosystems |
Compared with MAX4694EGE and TMUX1574RTER, MAX4694EBE uniquely balances ultra-small UCSP size, 1.8V logic compatibility at +3V, and guaranteed break-before-make - making it optimal for space-limited, battery-powered designs where thermal load is moderate.

FAQ
What is the maximum supply voltage for MAX4694EBE?
The MAX4694EBE supports a single positive supply from +2V to +11V. Its absolute maximum rating is +12V on V+, and exceeding this may cause permanent damage. Operation above +11V is not characterized or guaranteed - design margins should maintain ≤+11V under all conditions including ripple and transients.
Does MAX4694EBE support dual-supply operation?
No, MAX4694EBE is single-supply only. Unlike MAX4691/MAX4692/MAX4693, it lacks a V− pin and EN pin. Its pinout includes GND instead of V−, confirming fixed ground reference - dual ±V operation is not supported or electrically possible.
How are the four SPDT switches controlled in MAX4694EBE?
MAX4694EBE uses two digital inputs: A controls switches W and Y (W0/W1 and Y0/Y1), while B controls switches X and Z (X0/X1 and Z0/Z1). Each switch operates independently - setting A=0/B=0 closes W0, X0, Y0, Z0; A=1/B=1 closes W1, X1, Y1, Z1. No enable or address decoding is required.
What is the on-resistance flatness specification for MAX4694EBE?
On-resistance flatness is not specified for MAX4694EBE in the datasheet. While MAX4691–MAX4693 list 3.5Ω max flatness under ±4.5V dual supplies, MAX4694EBE's single-supply configuration omits this parameter - only RON (35Ω max @ +5V) and ΔRON (5Ω max @ +2.7V) are guaranteed.
Can MAX4694EBE be used in automotive applications?
MAX4694EBE is rated for -40°C to +85°C operation and meets industrial temperature requirements, but it is not AEC-Q200 qualified. For automotive use, system-level validation of solder joint reliability (especially under thermal cycling) and board-level ESD protection is required - Maxim's UCSP reliability notice explicitly ties performance to assembly method and PCB material.
