Product details
Overview
MAX4698EBT-T 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, cellular phone signal path selection, and relay replacement applications where low leakage (1nA max), fast switching (tON = 80ns max), and UCSP package size are critical.
For engineers reviewing the MAX4698EBT-T datasheet, MAX4698EBT-T pinout, MAX4698EBT-T application, or MAX4698EBT-T equivalent, this page delivers verified electrical parameters, UCSP bump mapping, break-before-make timing, leakage behavior across temperature, and direct alternatives for SPDT analog switch selection in space-constrained portable designs.
Technical Context
The MAX4698EBT-T implements a CMOS transmission-gate architecture with guaranteed break-before-make timing (2ns min at +3.3V), preventing momentary shorting between NO and NC paths during state transitions. Its digital control input accepts 1.8V logic levels when powered from +2.7V to +3.3V and TTL/CMOS levels up to +5.5V, enabling interoperability with mixed-voltage systems.
Rail-to-rail analog signal handling supports full V+ to GND range without distortion, while low crosstalk (-75dB at 100kHz) and high off-isolation (-75dB at 100kHz) ensure channel integrity in multi-path audio/video routing. On-resistance flatness remains ≤13Ω over the signal range, preserving linearity in precision signal switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration into Li-ion (3.0–3.7V) and USB-powered (5V) systems without level-shifting. |
| On-Resistance (RON) | 35Ω max at +3V, 20Ω max at +5V - ensures minimal voltage drop and power loss in low-voltage signal paths. |
| RON Matching | 2Ω max between NO and NC channels - critical for balanced differential switching and matched gain paths. |
| Break-Before-Make Time | 2ns min at +3.3V - guarantees no overlap conduction between NO and NC, eliminating signal shorting hazards. |
| Off-Isolation / Crosstalk | -75dB at 100kHz - maintains signal integrity in adjacent channels during simultaneous multi-path operation. |
| Leakage Current | 1nA max at +25°C - preserves battery life and DC accuracy in high-impedance sensor or bias networks. |
| Switching Speed | tON = 80ns max, tOFF = 25ns max - supports high-speed multiplexing in audio DAC/ADC interfaces and modem signal routing. |
Pinout & Package
MAX4698EBT-T uses a 6-bump chip-scale package (UCSP™) measuring 1.50mm × 1.02mm with 0.5mm bump pitch. The 3×2 solder bump array provides compact board footprint and thermal efficiency for portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | V+ | Positive supply input - must be applied before analog signals to prevent latch-up; absolute max +6V. |
| B2 | IN | Digital control input - 1.8V logic compatible at +2.7–3.3V supply; accepts up to +5.5V regardless of V+. |
| B3 | GND | Analog/digital ground reference - shared return path for supply and signal integrity; requires 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; handles rail-to-rail voltages. |
| A3 | NC | Normally closed analog terminal - connects to COM only when IN = low; complements NO for SPDT function. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Supports analog signals from GND to V+ without clipping or increased RON, enabling full dynamic range in audio and sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574DSGR | 4-channel SPDT, 5.5Ω RON at +3.3V, no guaranteed break-before-make, 1.8V logic compatible. | Higher channel count but larger 2mm × 1.5mm DSG package; better RON but lacks BBM assurance for fault-sensitive routing. | Select when lower on-resistance and multi-channel integration outweigh need for guaranteed BBM timing. |
| ADG732BRUZ-REEL7 | 32-channel SPST, 4Ω RON at +3V, no SPDT configuration, 1.8V logic compatible, TSSOP-48 package. | Massively higher channel density but requires external logic for SPDT emulation; 10× larger footprint than UCSP. | Select for high-channel-count multiplexing where SPDT functionality can be synthesized and board space permits TSSOP. |

FAQ
What is the guaranteed break-before-make time for MAX4698EBT-T?
The MAX4698EBT-T guarantees a minimum break-before-make time of 2ns at +3.3V supply, measured per Figure 2 in the datasheet. This parameter ensures no overlap conduction between NO and NC paths during switching transitions, which is critical for preventing signal shorting in audio routing and RF front-end applications. The MAX4698EBT-T is the only member of the MAX4696/MAX4697/MAX4698 family with this guaranteed feature.
Does MAX4698EBT-T support rail-to-rail analog signals?
Yes, the MAX4698EBT-T supports rail-to-rail analog signal handling from GND to V+, with minimal RON variation across the full range. At +3V supply, RON flatness is specified at 13Ω max, ensuring consistent performance for signals spanning the entire supply. This capability is confirmed in the Typical Operating Characteristics plots (toc02 and toc03) and explicitly stated in the Features list as "Rail-to-Rail® Signal Handling."
What is the maximum leakage current specification for MAX4698EBT-T at +25°C?
The MAX4698EBT-T specifies a maximum NO/NC off-leakage current of ±1nA at +25°C, tested under conditions of V+ = +3.6V, VCOM = 0.3V or 3.3V, and VNO/VNC = 3.3V or 0.3V. This low leakage is critical for preserving battery life and DC accuracy in high-impedance sensor interfaces and portable instrumentation. The value is documented in the Electrical Characteristics table on page 2 of the datasheet.
Which package type does MAX4698EBT-T use, and what are its dimensions?
The MAX4698EBT-T uses a 6-bump chip-scale package (UCSP™) with a footprint of 1.50mm × 1.02mm and 0.5mm bump pitch. The 3×2 solder bump array (B1–B3, A1–A3) is detailed in the Pin/Bump Description table on page 6. This package reduces PCB area significantly compared to SC70 or SOT-23 alternatives and is optimized for thin-profile portable electronics.
Can MAX4698EBT-T operate from a 1.8V supply?
No, the MAX4698EBT-T requires a minimum supply voltage of +2.0V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. While its digital inputs are 1.8V logic compatible when powered from +2.7V to +3.3V, the device itself cannot function below +2.0V. Operation at 1.8V would violate the guaranteed operating range and result in undefined switching behavior or failure to turn on.
