Product details
Overview
MAX4676EUT+T from Maxim Integrated is a single-pole, single-throw (SPST) analog switch with normally closed (NC) configuration, designed for precision signal routing in low-distortion, rail-to-rail applications. It delivers 3Ω maximum on-resistance (RON), 0.7Ω RON flatness, and <0.1nA off-leakage at +25°C, operating from dual ±2.7V to ±5.5V or single +2.7V to +5.5V supplies in a 6-pin SOT23 package - ideal for ADC front-ends and automated test equipment.
For engineers reviewing the MAX4676EUT+T datasheet, MAX4676EUT+T pinout, MAX4676EUT+T application, or MAX4676EUT+T equivalent, key selection criteria include NC switching behavior, sub-1nA leakage performance, 250MHz –3dB bandwidth, dual-supply rail-to-rail signal handling, and compatibility with 75Ω single-ended systems and high-reliability reed relay replacement.
Technical Context
The MAX4676EUT+T implements a CMOS transmission-gate architecture optimized for low charge injection (31pC typical) and minimal signal distortion across its full analog input range. Its logic-controlled NC topology ensures default conduction when IN is low, with fast switching (tON = 350ns typ, tOFF = 55ns typ under dual supply) and tight RON matching over temperature and voltage.
It supports both dual-supply (±2.7V to ±5.5V) and single-supply (+2.7V to +5.5V) operation without external biasing, maintaining specified RON, isolation (–75dB at 1MHz, dual supply), and bandwidth (250MHz) within its absolute max ratings - including V+ to V– ≤12V and continuous ±100mA channel current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | SPST, Normally Closed (NC) - conducts by default; breaks path when logic high applied to IN |
| On-Resistance (RON) | 3Ω max (dual ±5V); enables low insertion loss and minimal gain error in precision signal paths |
| RON Flatness | 0.7Ω max (dual supply); ensures consistent gain and linearity across full ±3.3V analog signal range |
| Off-Leakage Current | ±0.1nA max at +25°C; preserves accuracy in high-impedance sensor/ADC inputs and sample-hold circuits |
| Bandwidth (–3dB) | 250MHz (dual supply); supports high-speed video, RF sampling, and broadband communications routing |
| Supply Range | Dual ±2.7V to ±5.5V or single +2.7V to +5.5V; interoperable with mixed-signal systems using ±5V DACs or +3.3V logic |
| Charge Injection | 31pC typical; minimizes voltage glitch on sampled nodes in data-acquisition and multiplexed ADC systems |
Pinout & Package
MAX4676EUT+T is housed in a space-saving 6-pin SOT23-6 package (JEDEC MO-178AA), with exposed pad not electrically connected. Pin 1 is marked with a dot; device orientation follows standard SOT23 top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - V+ | Positive supply rail | Accepts +2.7V to +5.5V (single) or +2.7V to +5.5V (dual); must be powered before V– and logic inputs |
| 2 - COM | Analog common terminal | Primary signal path node; connects to NC when IN = low; rated for ±100mA continuous current |
| 3 - V− | Negative supply rail | Accepts –2.7V to –5.5V (dual only); clamping diodes protect against overvoltage beyond V− ±0.3V |
| 4 - GND | Ground reference | Logic and substrate reference; bypass with 0.1µF capacitor to V+ for noise immunity |
| 5 - NC | Normally closed analog terminal | Conducts to COM when IN = low; open-circuit when IN = high; 85pF off-capacitance minimizes crosstalk |
| 6 - IN | Logic control input | CMOS-compatible (VIH = 2.4V, VIL = 0.8V); 0.005µA leakage enables direct microcontroller GPIO drive |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from V− to V+ without clipping - critical for ±5V op-amp interfaces and audio line drivers |
| –75dB off-isolation at 1MHz (dual supply) | Prevents signal bleed-through in multi-channel multiplexers and sensitive receiver front-ends |
| 250MHz on-channel bandwidth | Enables transparent routing of composite video, USB 1.1, or baseband IF signals without attenuation |
| <1µA total supply current | Reduces system power budget in battery-powered DAS, portable instrumentation, and always-on monitoring nodes |
| Space-efficient 6-pin SOT23-6 | Offers same PCB footprint as discrete MOSFET switches while delivering superior matching, leakage, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4675EUT+T | Same package and pinout, but Normally Open (NO) configuration; identical RON, leakage, and bandwidth specs | Requires active-high enable for conduction; unsuitable where default-closed path is mandatory (e.g., safety interlocks) | Select MAX4675EUT+T only when circuit logic requires NO behavior - not a drop-in replacement for MAX4676EUT+T |
| ADG1419BRMZ-REEL | SPST NC switch in 10-lead MSOP; 0.9Ω RON max, but higher 1.5nA off-leakage and +4.5V to +16.5V single-supply only | Better RON for precision instrumentation, but lacks dual-supply support and fails rail-to-rail operation below +4.5V | Choose ADG1419BRMZ-REEL for ultra-low RON in high-voltage single-supply systems; not suitable for ±5V or low-leakage <1nA designs |
Compared with MAX4675EUT+T (NO variant) and ADG1419BRMZ-REEL (higher-voltage, higher-leakage alternative), MAX4676EUT+T uniquely combines NC default state, dual-supply flexibility, sub-0.1nA leakage, and rail-to-rail operation - making it the only choice for fail-safe, low-noise, mixed-supply analog routing.

FAQ
What is the default switching state of the MAX4676EUT+T?
The MAX4676EUT+T is a normally closed (NC) analog switch: COM and NC terminals are conductive when the IN pin is logic low (≤0.8V). Applying a logic high (≥2.4V) to IN opens the path. This fail-safe behavior ensures signal continuity during power-up, reset, or controller failure - a key distinction from the NO-configured MAX4675EUT+T.
Does the MAX4676EUT+T support rail-to-rail analog signals with single-supply operation?
Yes, the MAX4676EUT+T supports rail-to-rail analog signals from 0V to V+ in single-supply mode (V+ = +2.7V to +5.5V, V− = GND). Its CMOS transmission gate architecture maintains low RON and flatness across the full range, enabling accurate switching of audio, sensor, and video signals without headroom loss - unlike many switches that clip near supply rails.
What is the maximum allowable supply voltage difference between V+ and V− for the MAX4676EUT+T?
The MAX4676EUT+T specifies an absolute maximum V+ to V− differential of 12V. For example, valid dual-supply configurations include ±5V (10V total), ±4.5V (9V), or +5.5V/–2.7V (8.2V). Exceeding 12V risks permanent damage per the Absolute Maximum Ratings table - independent of individual rail voltages.
Can the MAX4676EUT+T be used in a +3.3V-only system with analog signals up to ±2.5V?
No - the MAX4676EUT+T cannot handle analog signals beyond its supply rails. In a +3.3V single-supply system (V− = GND), the input range is strictly 0V to +3.3V. To switch ±2.5V signals, dual-supply operation (e.g., V+ = +3.3V, V− = –3.3V) is required so the signal remains within V− to V+ (–3.3V to +3.3V).
How does charge injection of the MAX4676EUT+T affect precision sampling circuits?
The MAX4676EUT+T exhibits 31pC typical charge injection - the net charge dumped onto the COM node during switching. In a 1nF sampling capacitor, this causes a ~31mV glitch (Q/C), which can corrupt 12-bit+ ADC conversions. Mitigation includes using smaller hold capacitors, adding series resistance to limit peak current, or selecting sample timing to avoid critical acquisition windows - design guidance is provided in Maxim's application notes.
