Product details
Overview
MAX4591CUE+ from Maxim Integrated is a high-speed, precision quad SPST analog switch with four normally closed (NC) channels, designed for +12V or +15V single-supply operation. It delivers 16Ω max on-resistance, ≤80ns turn-on time, ≤45ns turn-off time, 5pC max charge injection, and 100pA max leakage at +25°C - enabling accurate signal routing in test equipment and guidance systems.
For engineers reviewing the MAX4591CUE+ datasheet, MAX4591CUE+ pinout, MAX4591CUE+ application, or MAX4591CUE+ equivalent, key selection criteria include guaranteed 1Ω max channel-to-channel RON match, 1.75Ω max RON flatness over signal range, ESD >2000V per Method 3015.7, and pin compatibility with DG611/DG211 families for drop-in replacement in legacy designs.
Technical Context
The MAX4591CUE+ implements CMOS transmission-gate architecture with logic-controlled NC switching, supporting analog signal ranges from V− to V+ (0V to +12V or +15V). Its internal protection diodes clamp signals exceeding supply rails, and it guarantees break-before-make timing only in MAX4593 variants - not applicable to MAX4591CUE+.
It operates across 0°C to +70°C ambient temperature, with leakage rising to 5nA max at +85°C and RON flatness degrading predictably per typical curves (toc02/toc03). Supply current remains below 1µA across temperature and voltage, ensuring minimal system power impact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 16Ω max at +12V supply - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| RON Match | 1Ω max between channels - enables matched gain/attenuation in multi-channel sampling or differential signal routing |
| RON Flatness | 1.75Ω max over 0–10V signal range - maintains consistent channel behavior across full analog input span |
| Charge Injection | 5pC max - limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| Leakage Current | 100pA max at +25°C, 5nA max at +85°C - prevents DC offset drift in high-impedance sensor interfaces |
| Switching Speed | tON ≤80ns, tOFF ≤45ns - supports multiplexing of signals up to ~10MHz without significant settling delay |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling margin during board assembly and field service |
Pinout & Package
MAX4591CUE+ is housed in a 16-pin TSSOP package (3.1mm × 5.1mm, 0.65mm pitch), rated for 0°C to +70°C operation. The package is RoHS-compliant and moisture-sensitive level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Drive ≥5V for logic high (open switch), ≤0.8V for logic low (closed switch) - compatible with TTL/CMOS levels |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal path endpoints - connect to downstream circuitry (e.g., ADC input, amplifier output) |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog terminals | Connected to COM when IN = low; isolated when IN = high - defines default-closed signal path |
| V+ (Pin 13) | Positive supply rail | +12V or +15V analog/digital supply - must be powered before logic inputs to avoid latch-up |
| GND (Pin 5) | Ground reference | Common return for analog and digital sections - requires low-impedance PCB connection |
| V− (Pin 4) | Negative supply terminal | Internally tied to GND in single-supply mode - must be connected to ground |
| N.C. (Pin 12) | No connection | Not internally bonded - leave unconnected and unpopulated on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Quad NC topology | Provides fail-safe closed-path default state - critical for safety-critical signal monitoring or biasing circuits |
| Guaranteed RON matching | 1Ω max mismatch enables precise ratiometric measurements across multiple channels without calibration |
| Low charge injection (5pC) | Minimizes hold-mode voltage step in sample-and-hold stages, reducing aperture error in data acquisition |
| Single +12V/+15V operation | Eliminates need for dual supplies - simplifies power design and reduces BOM count in industrial control modules |
| Pin compatibility with DG611/DG211 | Enables direct upgrade path from older analog switches without PCB redesign or firmware changes |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4591EUE+ | Same electrical specs, but rated for -40°C to +85°C operating range and packaged in 16-pin TSSOP | Suitable for extended-temperature industrial or automotive environments where MAX4591CUE+'s 0°C to +70°C range is insufficient | Select MAX4591EUE+ when operating outside commercial temperature range; otherwise MAX4591CUE+ offers cost advantage |
| DG611DN | Pin-compatible 16-pin SOIC variant with 20Ω RON, 100ns tON, and no guaranteed RON match or flatness specs | Acceptable for non-precision applications like audio routing or general-purpose signal gating where speed and matching are secondary | Choose DG611DN only if cost or legacy SOIC footprint drives selection; MAX4591CUE+ provides superior precision and speed |
Compared with MAX4591EUE+, MAX4591CUE+ trades extended temperature capability for lower unit cost in commercial-grade systems; versus DG611DN, it delivers tighter RON matching, faster switching, and guaranteed flatness - essential for metrology and data acquisition.

FAQ
What is the maximum supply voltage rating for MAX4591CUE+?
The MAX4591CUE+ has an absolute maximum V+ rating of +17V, but it is fully specified for reliable operation at +12V or +15V single-supply conditions. Operation above +15V is not characterized and may compromise RON, leakage, or lifetime reliability. Always observe the recommended operating range of 12V to 15V for MAX4591CUE+ to ensure compliance with all guaranteed specifications.
Does MAX4591CUE+ support dual-supply operation?
No, MAX4591CUE+ is designed exclusively for single-supply operation with V− tied to GND. For dual-supply or low-voltage applications (e.g., ±5V or +3.3V), refer to the MAX391 family instead. Attempting to apply negative voltage to V− on MAX4591CUE+ violates absolute maximum ratings and risks permanent damage.
Is MAX4591CUE+ pin-compatible with DG611 devices?
Yes, MAX4591CUE+ is explicitly stated as pin-compatible with DG611/DG612/DG613 and DG211/DG212/DG213 families in its datasheet. This includes identical pin assignments for IN, COM, NC/NO, V+, GND, and V− - enabling drop-in replacement in existing layouts without PCB modification.
What is the guaranteed on-resistance flatness specification for MAX4591CUE+?
MAX4591CUE+ guarantees 1.75Ω maximum on-resistance flatness over the full analog signal range (0V to +10V) when operated at +12V supply. This parameter is measured as the difference between maximum and minimum RON across the signal range and is critical for minimizing harmonic distortion in AC-coupled signal paths.
How does temperature affect leakage current in MAX4591CUE+?
At +25°C, MAX4591CUE+ exhibits ≤100pA max off-leakage; this increases to ≤5nA max at +85°C. The datasheet confirms this rise is monotonic and predictable, with typical curves (toc04) showing sub-nA behavior up to +70°C - aligning with MAX4591CUE+'s commercial temperature grade (0°C to +70°C).
