Product details
Overview
MAX4698EUB from Maxim Integrated is a single-pole/double-throw (SPDT) analog switch with break-before-make switching action, 35Ω max on-resistance at +3V supply, 2Ω max RON matching, and rail-to-rail signal handling from +2.0V to +5.5V. It operates in battery-powered audio routing and low-voltage communications circuits where low charge injection (8pC) and fast switching (tON = 80ns max) are critical.
For engineers reviewing the MAX4698EUB datasheet, MAX4698EUB pinout, MAX4698EUB application, or MAX4698EUB equivalent, this page delivers verified electrical parameters, UCSP package layout, SPDT functional behavior, break-before-make timing, and direct alternatives for signal-path redesign in portable electronics and interface conditioning.
Technical Context
The MAX4698EUB implements a CMOS transmission-gate architecture optimized for low-voltage operation, supporting 1.8V logic compatibility at +2.7V to +3.3V supplies and TTL/CMOS levels at +4.5V to +5.5V. Its internal control logic guarantees break-before-make timing (tBBM = 2ns min) to prevent signal shorting during channel transitions.
It features rail-to-rail analog signal handling across the full V+ range (0V to V+), with <1nA off-leakage at +25°C and -75dB off-isolation at 100kHz. The device maintains ≤13Ω RON flatness over its signal range, ensuring minimal distortion in audio and video paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 35Ω at +3V supply - ensures minimal voltage drop and power loss in low-voltage signal paths |
| RON matching | 2Ω max between NO and NC channels - enables precise differential or dual-path signal routing without gain mismatch |
| tON/tOFF | 80ns/25ns max at +2.7V - supports high-speed multiplexing in digital audio and serial interface switching |
| Break-before-make time | 2ns min - eliminates momentary short-circuit risk when toggling between analog sources |
| Off-isolation | -75dB at 100kHz - suppresses crosstalk between inactive and active signal paths in multi-channel systems |
| Charge injection | 8pC typical - minimizes glitch-induced DC offset in precision sampling and sensor front-ends |
| Supply range | +2.0V to +5.5V single supply - simplifies power design in mixed-voltage portable platforms |
Pinout & Package
The MAX4698EUB is housed in a 6-bump, 0.5mm pitch chip-scale package (UCSP™) measuring 1.50mm × 1.02mm. This ultra-compact footprint reduces PCB area by >70% versus SO-8 equivalents and supports fine-pitch automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | V+ | Positive supply input - must be applied before analog signals to avoid latch-up; absolute max +6V |
| B2 | IN | Digital control input - accepts 1.8V logic at +2.7V–+3.3V supply or TTL/CMOS at +4.5V–+5.5V |
| B3 | GND | Analog/digital ground reference - shared return path requiring low-impedance PCB connection |
| A1 | NO | Normally open analog terminal - connects to COM only when IN = high; bidirectional signal path |
| A2 | COM | Common analog terminal - serves as input or output depending on signal direction and switch state |
| A3 | NC | Normally closed analog terminal - connects to COM only when IN = low; complements NO for SPDT routing |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from 0V to V+ without clipping - essential for full-swing audio and sensor outputs |
| Guaranteed break-before-make | Prevents transient shorting between NO and NC paths - required for safe source selection in power-sensitive circuits |
| Low leakage current | <1nA off-leakage at +25°C - preserves signal integrity in high-impedance sensor and medical monitoring paths |
| High bandwidth | >200MHz -3dB bandwidth - enables clean switching of composite video, USB 1.1, and baseband RF signals |
| UCSP package | 1.50mm × 1.02mm footprint with 0.5mm bump pitch - enables ultra-thin portable designs and high-density layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG821BRMZ | 4.5Ω RON at +3V, but 1.6mm × 1.6mm MSOP-8 package - larger footprint, higher cost per mm² | Lacks guaranteed break-before-make; requires external timing control for safe channel switching | Choose ADG821BRMZ only if lower RON outweighs PCB area penalty and system-level timing complexity. |
| TS5A23157DCUR | 0.9Ω RON at +3V, 6-pin X2SON package (1.0mm × 1.0mm), but 10nA max off-leakage - 10× higher than MAX4698EUB | Higher leakage limits use in precision sensor interfaces; no specified break-before-make guarantee | Prefer TS5A23157DCUR for ultra-low-loss audio line driving where leakage is not critical and layout space is extremely tight. |
Compared with ADG821BRMZ and TS5A23157DCUR, the MAX4698EUB uniquely balances ultra-small UCSP size, guaranteed break-before-make, and sub-1nA leakage - making it optimal for battery-powered devices requiring both signal integrity and mechanical miniaturization.

FAQ
What is the guaranteed break-before-make timing for MAX4698EUB?
The MAX4698EUB guarantees a minimum break-before-make time of 2ns at +3.3V supply, measured under standard test conditions (Figure 2). This parameter is production-tested and ensures no overlap between NO and NC conduction paths during switching - critical for preventing signal shorts in audio and RF routing applications. The MAX4698EUB datasheet specifies tBBM across the full -40°C to +85°C temperature range.
Does MAX4698EUB support rail-to-rail analog signals?
Yes, the MAX4698EUB supports rail-to-rail analog signal handling from 0V to V+, meaning signals can swing across the entire supply range without clipping or increased distortion. This capability is confirmed in the "Analog Signal Range" specification (0V to V+) and validated in Typical Operating Characteristics (TOC01–TOC03). The MAX4698EUB maintains ≤13Ω RON flatness over this range, preserving signal fidelity in audio and sensor applications.
What is the maximum supply voltage rating for MAX4698EUB?
The absolute maximum supply voltage for MAX4698EUB is +6V, though recommended operating range is +2.0V to +5.5V. Exceeding +6V risks permanent damage, as stated in the Absolute Maximum Ratings table. The device draws only 1µA supply current at +3.3V or +5.5V, and its logic inputs tolerate up to +5.5V regardless of V+ level - a key feature documented in the Applications Information section of the MAX4698EUB datasheet.
How does MAX4698EUB compare to MAX4696EUB and MAX4697EUB?
The MAX4698EUB is an SPDT switch with both NO and NC terminals, whereas MAX4696EUB is SPST normally open and MAX4697EUB is SPST normally closed. All three share identical UCSP-6 packaging, supply range (+2.0V to +5.5V), RON specs, and timing performance. Only MAX4698EUB provides break-before-make functionality and RON matching (2Ω max) between its two switched paths - differentiating it for dual-source selection tasks where channel coordination is mandatory.
What is the thermal performance of MAX4698EUB in its UCSP package?
The MAX4698EUB UCSP package has a thermal resistance (θJA) of 125°C/W and a continuous power dissipation limit of 808mW at +70°C ambient, derating by 10.1mW/°C above that temperature. Its operating range is -40°C to +85°C, and all electrical parameters are production-tested at +25°C then correlated across temperature. The MAX4698EUB's low 1µA supply current and 35Ω RON minimize self-heating, supporting reliable operation in thermally constrained handheld enclosures.
