Product details
Overview
MAX4732EBL+T from Maxim Integrated is a dual, normally closed (NC), single-pole/single-throw (SPST) analog switch IC operating from a single +2V to +11V supply. It delivers 50Ω max on-resistance at +3V, 3.5Ω max channel-to-channel RON matching, and rail-to-rail signal handling with <0.1nA leakage current - ideal for low-power audio routing and battery-powered data-acquisition systems.
For engineers reviewing the MAX4732EBL+T datasheet, MAX4732EBL+T pinout, MAX4732EBL+T application, or MAX4732EBL+T equivalent, key selection criteria include NC-switch topology, UCSP-9 package footprint, guaranteed RON flatness ≤9Ω, TTL/CMOS logic compatibility, and -72dB off-isolation at 1MHz.
Technical Context
The MAX4732EBL+T implements two independent NC SPST switches using CMOS process technology, with internal protection diodes enabling robust overvoltage tolerance up to V+ + 0.3V. Its logic inputs accept rail-to-rail voltage levels, ensuring reliable switching across the full +2V to +11V supply range without external level-shifting.
Each switch exhibits matched on-resistance characteristics (≤3.5Ω ΔRON at +3V), low charge injection (7.5pC), and high-frequency performance with 300MHz -3dB bandwidth and -108dB crosstalk at 1MHz - supporting precision signal routing in mixed-signal portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - supports direct integration into Li-ion, 3.3V, and 5V systems without regulators |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal signal attenuation in low-voltage sensor interfaces |
| RON Matching | 3.5Ω max between channels at +3V - critical for matched gain paths in differential or dual-channel circuits |
| Leakage Current | <0.1nA at +25°C - preserves battery life in always-on monitoring nodes |
| Off-Isolation | -72dB at 1MHz - prevents signal coupling between inactive channels in A/V multiplexing |
| Crosstalk | -108dB at 1MHz - enables simultaneous high-fidelity routing of multiple analog signals |
| Turn-On/Off Time | 170ns / 70ns max at +3V - suitable for fast-switching data acquisition and TDM applications |
Pinout & Package
The MAX4732EBL+T is housed in a 1.52mm × 1.52mm, 9-bump UCSP (Ultra-Chip-Scale Package) with bottom-side bumps. This wafer-level chip-scale package minimizes PCB area and thermal resistance while maintaining compatibility with standard reflow processes per JEDEC J-STD-020.

| A2 | COM1 | Common analog node for Switch 1 - bidirectional I/O path shared with NC1 and NO1 |
| A3 | GND | Digital ground reference - must be connected to system ground plane for logic integrity |
| B1 | IN1 | Digital control input for Switch 1 - active-low logic controls NC1/COM1 connection state |
| B3 | IN2 | Digital control input for Switch 2 - independent active-low logic for NC2/COM2 switching |
| C1 | V+ | Positive supply input - bypass with ≥0.1µF capacitor near package for stability above +5V |
| C2 | COM2 | Common analog node for Switch 2 - bidirectional path shared with NC2 |
| C3 | NC2 | Normally closed analog terminal for Switch 2 - connects to COM2 when IN2 = LOW |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4732ETA+ | 8-pin TDFN-EP package (3mm × 3mm); exposed pad improves thermal dissipation | Better suited for higher-current or thermally constrained layouts where UCSP rework is impractical | Select when board assembly uses standard TDFN footprint and thermal management requires exposed pad |
| ADG722BRMZ-REEL7 | 5V-only supply range; 4Ω max RON at +5V; different pinout and NC/NO configuration | Optimized for fixed 5V industrial systems, not battery-powered wide-supply designs | Choose only if supply is strictly +5V and lower RON outweighs supply flexibility and package size trade-offs |
Compared with MAX4732ETA+, the MAX4732EBL+T saves >80% board area but lacks thermal pad; versus ADG722BRMZ-REEL7, it supports wider supply range (+2V to +11V) and ultra-low leakage, making it superior for portable, multi-voltage applications despite higher RON.

FAQ
What is the maximum supply voltage rating for the MAX4732EBL+T?
The MAX4732EBL+T has an absolute maximum supply voltage (V+) of +12V referenced to GND, with recommended operational limit at +11V. When operating near this upper bound, a minimum 0.1µF ceramic bypass capacitor must be placed directly between V+ and GND pins to ensure stability and prevent latch-up. Exceeding +12V risks permanent device damage per Absolute Maximum Ratings.
Does the MAX4732EBL+T support rail-to-rail analog signal operation?
Yes, the MAX4732EBL+T supports true rail-to-rail analog signal operation - signals from GND to V+ pass through the switches with minimal distortion or RON variation. This capability is confirmed across the full specified supply range (+2V to +11V) and is validated by on-resistance curves showing <9Ω flatness over the entire analog input range at +3V.
What is the logic polarity of the control inputs on the MAX4732EBL+T?
The MAX4732EBL+T features active-low logic control: IN1 and IN2 must be driven LOW (≤0.8V) to close the NC switches (connect NC1↔COM1 and NC2↔COM2), and HIGH (≥2.0V at +5V supply) to open them. This behavior is explicitly defined in the truth tables and functional diagrams for MAX4732 variants, distinguishing it from the NO-configured MAX4731.
Can the MAX4732EBL+T be used in a +3.3V system with standard 3.3V GPIOs?
Yes, the MAX4732EBL+T is fully compatible with +3.3V systems. Its VIH threshold is guaranteed ≥2.0V and VIL ≤0.8V across temperature, allowing direct interfacing with 3.3V CMOS outputs. For optimal performance, drive IN1/IN2 rail-to-rail (0V/3.3V) to minimize power consumption and ensure robust switching margins.
What is the thermal profile requirement for soldering the MAX4732EBL+T UCSP package?
The MAX4732EBL+T UCSP requires adherence to JEDEC J-STD-020A, paragraph 7.6, Table 3 for IR/vapor-phase reflow - specifically infrared peak temperature ≤+220°C (15s) or vapor-phase peak ≤+215°C (60s). Preheating is mandatory; hand soldering and wave soldering are prohibited due to bump metallurgy limitations.
