Product details
Overview
MAX4648EUT+T from Maxim Integrated is a single-pole/single-throw (SPST) analog switch with normally open (NO) configuration, designed for bidirectional rail-to-rail signal routing in high-precision analog and mixed-signal systems. It delivers 25Ω max on-resistance at ±15V supplies, 2Ω max on-resistance flatness, 1nA max off-leakage at +25°C, and operates from dual ±4.5V to ±20V or single +9V to +36V supplies - enabling use in telecom line cards and test instrumentation front-ends.
For engineers reviewing the MAX4648EUT+T datasheet, MAX4648EUT+T pinout, MAX4648EUT+T application, or MAX4648EUT+T equivalent, key selection criteria include guaranteed RON flatness over full signal range, sub-100ns switching times (tON/tOFF = 100ns typ), low charge injection (4pC), and SOT23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4648EUT+T implements a CMOS-based SPST switch architecture with complementary transistor pairs optimized for symmetric conduction and minimal signal distortion. Its control logic accepts standard TTL/CMOS input levels (VIH = 2.4V, VIL = 0.8V) without requiring a separate logic supply (VL), simplifying biasing in dual-supply systems.
It supports true rail-to-rail analog signal handling across the full supply range (VCOM from V− to V+), with off-isolation of −92dB at 1MHz and THD of 0.006% (20Hz–20kHz), making it suitable for audio routing and precision measurement signal paths where harmonic integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 25Ω max at ±15V supplies - ensures minimal voltage drop and gain error in precision signal paths |

Pinout & Package
MAX4648EUT+T is housed in a RoHS-compliant 6-pin SOT23 package (package code U6SN-1), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads optimized for reflow soldering and high-density layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO (Normally Open) | Analog switch terminal disconnected from COM when IN = 0; connects to COM when IN = 1 |
| 2 | V− | Negative supply rail input - must be connected for dual-supply operation; tied to GND for single-supply use |
| 3 | IN | Digital control input - active-high logic; no VL supply required; compatible with 3V/5V logic families |
| 4 | GND | Ground reference for logic and substrate - must be connected even in dual-supply configurations |
| 5 | V+ | Positive supply rail input - sets upper analog signal limit (VCOM ≤ V+) |
| 6 | COM | Common analog terminal - bidirectional signal path shared between NO and internal switch element |
Key Features
| Feature | Design Value |
|---|---|
| No VL logic supply needed | Eliminates dedicated logic rail - reduces BOM count and simplifies power tree in dual-supply systems |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables direct interfacing with op-amp outputs and DACs without level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRMZ-REEL7 | Higher RON (3.8Ω typ), lower leakage (0.15nA), requires VL supply | Better for ultra-low-leakage medical sensor front-ends; less suitable for dual-supply telecom without VL rail | Select when sub-nA leakage and <5Ω RON outweigh need for VL-free operation |
| TS5A23157DCUR | Single-supply only (+1.65V to +5.5V), 0.9Ω RON, smaller 6-pin SC70 package | Optimized for portable battery-powered audio routing; incompatible with ±15V or +36V systems | Select for low-voltage, high-density consumer audio designs - not a dual-supply replacement |
Compared with ADG1419BRMZ-REEL7 and TS5A23157DCUR, the MAX4648EUT+T uniquely supports wide dual-supply operation without VL, delivering 25Ω RON and 1nA leakage in a proven SOT23-6 package - making it optimal for telecom infrastructure and industrial test gear where supply flexibility and reliability are prioritized over ultra-low RON.

FAQ
What is the maximum supply voltage range supported by the MAX4648EUT+T?
The MAX4648EUT+T supports dual-supply operation from ±4.5V to ±20V and single-supply operation from +9V to +36V. Absolute maximum ratings specify V+ up to +44V and V− down to −44V, but continuous operation beyond ±20V or +36V violates the specified operating range and risks reliability degradation. Always observe the recommended supply limits in the Electrical Characteristics table for guaranteed performance.
Does the MAX4648EUT+T require a separate logic supply voltage (VL)?
No, the MAX4648EUT+T does not require a separate VL supply. Its digital control input (IN) accepts standard TTL/CMOS logic levels (VIH = 2.4V min, VIL = 0.8V max) referenced to GND, regardless of whether the device is powered from dual ±15V or single +12V supplies. This eliminates the need for an additional logic rail and simplifies system power architecture.
What is the typical on-resistance flatness of the MAX4648EUT+T and why does it matter?
The MAX4648EUT+T guarantees on-resistance flatness of 2Ω max over its full specified analog signal range. This means the variation in RON across all input voltages (e.g., from V− to V+) stays within 2Ω - critical for minimizing harmonic distortion and amplitude-dependent gain errors in audio, instrumentation, and precision measurement applications where signal integrity must remain consistent across dynamic range.
Can the MAX4648EUT+T be used in single-supply applications with a grounded V− pin?
Yes, the MAX4648EUT+T can operate in single-supply mode by connecting V− to GND and applying V+ between +9V and +36V. In this configuration, the analog signal range extends from 0V to V+, and RON increases slightly (60Ω max at +12V). The device retains all core functionality including rail-to-rail signal handling, 100ns switching, and 1nA leakage - making it viable for industrial sensor interfaces and DC-coupled multiplexers.
How does the MAX4648EUT+T compare to the MAX4647EUT+T in terms of switching behavior?
The MAX4648EUT+T is a normally open (NO) SPST switch: COM connects to NO only when IN = 1. In contrast, the MAX4647EUT+T is normally closed (NC): COM connects to NC when IN = 0 and disconnects when IN = 1. Both share identical electrical specs (RON, leakage, speed, supply range), but their default states differ - MAX4648EUT+T provides fail-open safety in power-sensitive systems, while MAX4647EUT+T offers fail-closed continuity.
