Product details
Overview
MAX4591CUE from Maxim Integrated is a high-speed, quad single-pole/single-throw (SPST) analog switch with normally closed (NC) configuration, designed for +12V or +15V single-supply operation. It delivers 16Ω max on-resistance, ≤80ns turn-on time, 5pC max charge injection, 100pA max leakage, and guaranteed 1Ω max channel-to-channel RON match - enabling precision 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 its NC-switch topology, TSSOP-16 package, +70°C commercial temperature grade, low RON flatness (≤1.75Ω), and compatibility with DG611/DG211 pinouts for drop-in replacement in legacy analog switching designs.
Technical Context
The MAX4591CUE implements CMOS-based SPST switches with logic-controlled gate drivers optimized for single-supply operation. Its internal architecture ensures matched RON across all four channels and minimizes charge injection via balanced transistor sizing and layout symmetry.
It supports analog signal ranges from V− (GND) to V+, with clamping diodes protecting inputs against overvoltage. The device guarantees performance over 0°C to +70°C and maintains <5nA COM on-leakage at +85°C - critical for sample-and-hold accuracy and low-distortion audio routing.
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 (ΔRON) | 1Ω max between channels - enables accurate differential signal switching without channel-to-channel gain mismatch. |
| Charge injection | 5pC max - limits voltage glitch in sample-and-hold circuits and preserves ADC input integrity. |
| Turn-on time (tON) | 80ns max - supports high-speed multiplexing in automated test equipment operating up to 10MHz. |
| Off-leakage current | 100pA max at +25°C - maintains signal integrity in high-impedance sensor interfaces and battery-powered systems. |
| Analog signal range | V− to V+ (0V to +12V or +15V) - allows rail-to-rail analog signal handling without external level-shifting. |
| ESD rating | >2000V per Method 3015.7 - provides robust handling during board assembly and field service. |
Pinout & Package
MAX4591CUE is housed in a 16-pin TSSOP package (4.4mm × 5mm body, 0.65mm pitch), optimized for space-constrained PCB layouts while maintaining thermal performance up to +70°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | Logic input (IN1–IN4) | CMOS-compatible control lines: ≤0.8V = logic low (switch ON for NC), ≥5V = logic high (switch OFF). |
| 2, 7, 10, 15 | Analog common terminal (COM1–COM4) | Primary signal path connection point; must be routed with controlled impedance for high-frequency signals. |
| 3, 6, 11, 14 | Normally closed terminal (NC1–NC4) | Default-connected path when INx = low; open-circuited when INx = high - used for fail-safe signal routing. |
| 4 | Negative supply (V−) | Internally tied to GND in single-supply mode; required for proper biasing of internal protection diodes. |
| 5 | Ground (GND) | Reference node for logic inputs and substrate connection; must be low-inductance for noise-sensitive applications. |
| 13 | Positive supply (V+) | +12V or +15V analog power rail; sequencing before logic inputs prevents latch-up and overvoltage stress. |
| 12 | No connection (N.C.) | Unbonded pad - must remain unconnected to avoid parasitic coupling or ESD path disruption. |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) switch topology | Ensures default signal continuity during power loss or logic fault - critical for safety-critical guidance and control systems. |
| Guaranteed RON flatness ≤1.75Ω | Maintains consistent gain across full analog input range (0V to +12V), eliminating distortion in video and audio signal paths. |
| Break-before-make timing (MAX4593 only) | Not applicable - MAX4591CUE is pure NC SPST; no inter-channel switching overlap or signal shorting risk. |
| PIN-compatible with DG611/DG211 | Enables direct PCB-level replacement in existing designs using industry-standard quad analog switch footprints. |
| Low 5pC charge injection | Reduces settling error in precision data acquisition systems, allowing faster sampling rates without added hold capacitor size. |
Applications
| Test Equipment | Sample-and-Hold Circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG611DN | 16-pin SOIC package; 18Ω RON max; 100pA leakage; same NC topology and pinout. | Higher thermal resistance (SOIC vs. TSSOP); less suitable for high-density or thermally constrained layouts. | Select DG611DN only if SOIC footprint is mandatory and board area permits larger package. |
| MAX4591EUE | Same electrical specs but rated for −40°C to +85°C extended temperature range. | Required for automotive, industrial, or outdoor deployments where ambient exceeds +70°C. | Choose MAX4591EUE when operating beyond commercial temperature limits - no PCB change needed. |
Compared with DG611DN, MAX4591CUE offers superior thermal performance and smaller footprint; compared with MAX4591EUE, it trades extended temperature capability for lower cost and optimized supply chain availability in commercial-grade programs.

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. Operating above +15V risks exceeding guaranteed RON, leakage, and timing specifications - always observe the +12V/+15V recommended supply range for MAX4591CUE to ensure compliance with datasheet performance.
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, Maxim specifies the MAX391 family instead. Attempting to apply negative voltage to V− on MAX4591CUE violates absolute maximum ratings and may cause permanent damage.
Is MAX4591CUE pin-compatible with DG611 devices?
Yes, MAX4591CUE is pin-compatible with DG611/DG211 series devices in TSSOP-16 and SOIC-16 packages. The IN, COM, NC, V+, V−, and GND pin assignments match exactly - enabling drop-in replacement without PCB modification, provided the supply voltage and temperature requirements align.
What is the guaranteed on-resistance match between channels for MAX4591CUE?
MAX4591CUE guarantees ≤1Ω maximum on-resistance match (ΔRON) between any two channels at +25°C with +12V supply. This specification holds across the full 0°C to +70°C commercial temperature range and ensures consistent gain and signal fidelity in multi-channel instrumentation designs using MAX4591CUE.
How does charge injection affect system performance when using MAX4591CUE?
MAX4591CUE specifies ≤5pC maximum charge injection, which directly impacts settling time and voltage error in sample-and-hold and switched-capacitor circuits. In a 1nF hold capacitor, this yields ≤5mV glitch - acceptable for 12-bit systems but requiring additional filtering or larger capacitors for 14-bit+ precision applications using MAX4591CUE.
