Product details
Overview
MAX4697EBT-T from Maxim Integrated is a normally closed (NC), single-pole/single-throw (SPST) analog switch operating from a single +2.0V to +5.5V supply, delivering 35Ω max on-resistance at +3V, 2Ω max RON matching, and 80ns max turn-on time. It supports rail-to-rail signal handling and is used in battery-operated audio routing and relay replacement where low leakage (<1nA at +25°C) and fast switching are critical.
For engineers reviewing the MAX4697EBT-T datasheet, MAX4697EBT-T pinout, MAX4697EBT-T application, or MAX4697EBT-T equivalent, this page provides verified electrical parameters, UCSP package layout, real-world use scenarios, and functionally comparable alternatives for low-voltage analog signal path design.
Technical Context
The MAX4697EBT-T implements a CMOS transmission-gate architecture with complementary P- and N-channel devices enabling rail-to-rail analog conduction and 1.8V logic compatibility at +2.7V to +3.3V supplies. Its digital control input accepts TTL/CMOS levels up to +5.5V independent of V+, supporting mixed-voltage system interfacing.
As a normally closed switch, it conducts by default when IN = LOW (≤0.5V), opens when IN = HIGH (≥1.4V), and guarantees sub-25ns turn-off with <1nA off-leakage across –40°C to +85°C. The device exhibits 13Ω max RON flatness over full signal range and –75dB off-isolation at 100kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +5.5V single supply - enables direct integration into 2.5V, 3.3V, and 5V systems without level shifters. |
| On-Resistance (RON) | 35Ω max at +3V - ensures minimal signal attenuation and voltage drop in low-power audio and sensor paths. |
| RON Matching | 2Ω max between channels - critical for matched gain/phase in differential or dual-path signal routing. |
| Turn-On/Off Time | tON = 80ns max, tOFF = 25ns max - supports high-speed multiplexing in portable communications circuits. |
| Off-Leakage Current | ±1nA max at +25°C - preserves battery life and signal integrity in always-on sensor monitoring nodes. |
| Bandwidth | >200MHz –3dB - suitable for composite video, USB 1.1, and baseband RF signal switching. |
| Logic Compatibility | 1.8V CMOS at +2.7V–+3.3V; TTL/CMOS at +4.5V–+5.5V - simplifies host MCU interface across voltage domains. |
Pinout & Package
MAX4697EBT-T uses a 6-bump, 0.5mm pitch chip-scale package (UCSP™) measuring 1.50mm × 1.02mm. The package features a 3×2 solder bump array with bottom-side terminations only - no leads or exposed pads.
| 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 - active-low logic: IN ≤ 0.5V closes switch, IN ≥ 1.4V opens switch. |
| B3 | GND | Analog/digital ground reference - requires low-impedance connection to minimize noise coupling. |
| A1 | NC | Normally closed analog terminal - conducts to COM when IN = LOW; open when IN = HIGH. |
| A2 | COM | Common analog port - bidirectional signal path; connects to NC when switch is closed. |
| A3 | - | No connection - unused bump; electrically isolated and not bonded internally. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Supports analog signals from GND to V+ without clipping - eliminates need for external biasing in portable audio front-ends. |
| Low Charge Injection (8pC) | Minimizes voltage glitch on sampled-hold nodes - essential for precision ADC input multiplexing. |
| –75dB Off-Isolation @ 100kHz | Prevents crosstalk between inactive channels in multi-signal routing applications like PCMCIA card muxing. |
| UCSP Footprint (1.50mm × 1.02mm) | Reduces PCB area by >70% vs. SOT-23 - enables ultra-compact designs in cellular phones and wearables. |
| Guaranteed Break-Before-Make | Not applicable - MAX4697EBT-T is SPST NC; break-before-make is exclusive to MAX4698 SPDT variant. |
Applications
| Audio Signal Routing | Portable Sensor Multiplexing |
|---|---|
|
Use Scenario: Switching microphone or headphone signals in MP3 players and Bluetooth headsets with automatic mute during state transitions. IC Role / Device Role / Timing Role: Normally closed analog switch providing default audio path continuity until firmware commands disconnect.

IC Role / Device Role / Timing Role: Low-leakage analog gate isolating inactive sensors to prevent loading and power drain on shared ADC inputs. Use Value: ±1nA off-leakage extends battery life in sleep mode; rail-to-rail operation accommodates unbuffered sensor outputs. |
| Relay Replacement | Communications Circuit Switching |
|

IC Role / Device Role / Timing Role: Solid-state SPST NC switch providing fail-safe closed path during power loss or reset events. Use Value: No coil drive circuitry needed; 80ns tON enables rapid test sequence execution; UCSP footprint reduces board cost. |
Use Scenario: Routing RF IF or baseband signals between transceiver chains and antenna switches in cellular modems and 4G/LTE modules. IC Role / Device Role / Timing Role: High-bandwidth analog switch managing signal path selection without degrading SNR or group delay. Use Value: >200MHz –3dB bandwidth supports LTE Band 13/17; –75dB off-isolation prevents inter-band interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4696EBT-T | SPST normally open (NO) configuration; identical RON, timing, and package - complementary logic polarity only. | Used where default-open behavior is required (e.g., safety-critical disconnect on power-up). | Select MAX4696EBT-T when system logic demands active-HIGH enable; MAX4697EBT-T for active-LOW default-closed operation. |
| TMUX1574DSGR | 4-channel SPDT, 5.5Ω RON at +3.3V, 1.8V logic compatible, but larger 2mm × 1.5mm DSBGA package. | Offers multi-channel integration but lacks guaranteed NC default state and UCSP size advantage. | Choose TMUX1574DSGR only if multi-channel consolidation outweighs board space penalty and NC fail-safe requirement. |
Compared with MAX4696EBT-T, MAX4697EBT-T provides inverted control logic and fails closed - critical for safety or default-path applications; versus TMUX1574DSGR, it trades channel count and lower RON for minimal footprint and deterministic NC behavior in space-constrained portable designs.

FAQ
What is the default state of the MAX4697EBT-T analog switch?
The MAX4697EBT-T is a normally closed (NC) SPST analog switch: it conducts between COM and NC terminals when the IN control input is logic LOW (≤0.5V). When IN is driven HIGH (≥1.4V), the switch opens. This fail-safe default-closed behavior makes MAX4697EBT-T ideal for applications requiring continuity during power-down or reset conditions, such as audio mute circuits or sensor bias paths.
Does the MAX4697EBT-T support rail-to-rail analog signal operation?
Yes, the MAX4697EBT-T supports true rail-to-rail analog signal handling - signals from GND to V+ pass through the switch with minimal distortion or RON variation. At +3V supply, RON flatness is specified at 13Ω max over the full 0V to +3V range, and the device maintains <1nA leakage across temperature. This capability eliminates external level-shifting components in portable audio and sensor interfaces.
What package type and dimensions does the MAX4697EBT-T use?
The MAX4697EBT-T uses a 6-bump, 0.5mm pitch chip-scale package (UCSP™) measuring exactly 1.50mm × 1.02mm. It features a 3×2 solder bump array on the bottom surface only - no leads, no exposed thermal pad. This ultra-compact footprint reduces PCB area by over 70% compared to SOT-23 packages and is optimized for high-density portable designs like cellular phones and wearables.
Can the MAX4697EBT-T operate from a 1.8V supply?
No, the MAX4697EBT-T has a minimum supply voltage of +2.0V per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below +2.0V is not characterized or guaranteed - RON, switching speed, and logic threshold margins degrade outside the +2.0V to +5.5V range. For 1.8V systems, consider purpose-designed low-voltage switches such as the TMUX1574 or ADG8xx series.
How does the MAX4697EBT-T compare to the MAX4698EBT-T in terms of functionality?
The MAX4697EBT-T is an SPST NC switch with two terminals (COM and NC); the MAX4698EBT-T is an SPDT switch with three terminals (COM, NO, NC) and guaranteed break-before-make timing. MAX4697EBT-T cannot perform signal path selection between two destinations - it only opens or closes a single path. Use MAX4697EBT-T for simple on/off control; choose MAX4698EBT-T only when dual-output routing with controlled transition timing is required.
