Product details
Overview
The MAX4591CSE 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 20Ω max on-resistance, ≤80ns turn-on time, 100pA max leakage, 5pC max charge injection, and 1.75Ω max RON flatness - enabling precision signal routing in test equipment and audio/video switching systems.
For engineers reviewing the MAX4591CSE datasheet, MAX4591CSE pinout, MAX4591CSE application, or MAX4591CSE equivalent, key selection criteria include guaranteed channel-to-channel RON match (≤1Ω), ESD robustness (>2000V), low-temperature drift leakage (5nA max at +85°C), and pin compatibility with DG611/DG211 families for drop-in upgrades.
Technical Context
This device implements CMOS-based SPST switching architecture with logic-controlled gate drive, supporting rail-to-rail analog signal ranges up to V+ (12V or 15V) and GND. Its internal structure ensures matched transistor pairs per channel to guarantee ≤1Ω RON matching and ≤1.75Ω RON flatness over the full signal range.
Designed for single-supply use only, the MAX4591CSE integrates ESD protection diodes rated >2000V (Method 3015.7) and features break-before-make timing (5–20ns) only in the MAX4593 variant - not applicable to MAX4591CSE, which uses independent SPST NC switches without inter-channel timing coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 20Ω max at +12V supply - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| Turn-on time (tON) | 80ns max - enables high-speed multiplexing in data acquisition and real-time control loops. |
| Charge injection | 5pC max - reduces sampling error in sample-and-hold circuits and ADC front-ends. |
| Off-leakage current | 100pA max at +25°C - preserves signal integrity in high-impedance sensor interfaces. |
| RON flatness | 1.75Ω max - maintains consistent gain and linearity across full analog input range (0V to V+). |
| ESD rating | >2000V per Method 3015.7 - supports robust handling and board-level reliability without external protection. |
| Supply range | +12V or +15V single supply - simplifies power design by eliminating dual-rail requirements. |
Pinout & Package
MAX4591CSE is housed in a 16-pin narrow SO (Small Outline) package with standard 150-mil body width and 1.27mm pitch. Pin functions are fully defined per Maxim's functional diagrams and truth tables for the MAX4591 family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Drive ≥5V for logic "1" (open circuit), ≤0.8V for logic "0" (closed path); active-low logic for NC function. |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Signal return path shared with NC contacts; must remain within V− to V+ range (0V to +15V). |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog outputs | Connected to COM when IN = 0; open when IN = 1 - provides fail-safe closed-path default state. |
| V+ (Pin 13) | Positive supply | +12V or +15V analog/digital supply; powers internal switch array and logic interface. |
| GND (Pin 5) | Ground reference | Common return for logic and analog sections; requires low-impedance connection to minimize noise coupling. |
| V− (Pin 4) | Negative supply | Internally tied to GND; not used as negative rail - device operates single-supply only. |
| N.C. (Pin 12) | No connection | Unbonded pad; must be left floating - no electrical or thermal function. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON match | ≤1Ω max between all four channels - eliminates gain mismatch in multi-channel instrumentation. |
| Low charge injection | 5pC max - prevents DC offset errors in precision sampling and hold applications. |
| High off-isolation | 72dB at 10MHz - suppresses crosstalk between inactive channels in dense PCB layouts. |
| Temperature-stable leakage | 5nA max at +85°C - ensures reliable operation in industrial and military environments. |
| Pin compatibility | Direct replacement for DG611 and DG211 families - enables legacy system upgrades without layout changes. |
Applications
| Test Equipment | Audio/Video Switching |
|---|---|
Use Scenario: Automated test systems routing multiple sensor signals to a single DMM or oscilloscope input. IC Role / Device Role / Timing Role: Quad NC analog switch providing fail-closed signal path during power-up or controller reset. Use Value: Ensures continuity of critical measurement paths before firmware initialization - avoids open-circuit faults during boot. | Use Scenario: Consumer AV receivers selecting between HDMI, coaxial, and optical audio sources. IC Role / Device Role / Timing Role: Low-distortion analog switch routing line-level audio signals with minimal THD+N degradation. Use Value: 20Ω RON and 1.75Ω flatness preserve frequency response flatness (<±0.1dB) across 20Hz–20kHz band. |

IC Role / Device Role / Timing Role: Charge-injection-optimized switch gating the hold capacitor during acquisition phase. Use Value: 5pC max charge injection limits aperture error to <1LSB in 16-bit systems sampling at 1MSPS. | Use Scenario: Secure voice communication units requiring ESD-hardened signal routing in field-deployed radios. IC Role / Device Role / Timing Role: Ruggedized analog switch isolating antenna receive paths from baseband processing stages. Use Value: >2000V ESD rating meets MIL-STD-883 Method 3015.7 - eliminates need for external TVS diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DG611DN | Higher RON (45Ω typ), slower tON (120ns), no guaranteed RON match spec | Limited to non-critical signal routing where precision matching is unnecessary | Select DG611DN only if cost sensitivity outweighs performance requirements for RON flatness and speed. |
| MAX4617ESE | Lower supply voltage (up to +12V only), 10Ω RON, but NO-only configuration (no NC function) | Suitable for new designs needing lower on-resistance but unable to use NC default state | Choose MAX4617ESE when fail-open behavior is acceptable and tighter RON tolerance is required. |
Compared with DG611DN and MAX4617ESE, the MAX4591CSE uniquely combines NC default state, guaranteed 1Ω RON matching, and 5pC charge injection - making it irreplaceable in safety-critical sample-and-hold and self-test architectures requiring deterministic closed-path behavior at power-on.

FAQ
What is the maximum operating supply voltage for the MAX4591CSE?
The MAX4591CSE supports absolute maximum ratings of −0.3V to +17V on V+, with guaranteed operation at +12V or +15V single supply. Operation above +15V risks permanent damage, and the device is not rated for dual-supply configurations - V− must be tied to GND. The MAX4591CSE datasheet specifies full parametric performance only at +12V and +15V nominal supplies.
Does the MAX4591CSE support break-before-make switching?
No, the MAX4591CSE does not implement break-before-make functionality. It contains four independent normally closed (NC) SPST switches with no timing coordination between channels. Break-before-make behavior is exclusive to the MAX4593 variant (which integrates two NO and two NC switches with controlled transition timing), and is not present in MAX4591CSE's architecture or truth table.
What is the guaranteed on-resistance flatness specification for MAX4591CSE at +12V supply?
The MAX4591CSE guarantees 1.75Ω maximum on-resistance flatness (RFLAT(ON)) over the full analog signal range (V− to V+) when operated at +12V supply. This parameter is measured with ICOM = −10mA and VNO/VNC swept across 3V, 6V, and 9V - ensuring consistent signal gain and linearity in precision analog gain blocks and programmable attenuators.
Can the MAX4591CSE be used with a +5V supply?
No, the MAX4591CSE is not specified for +5V operation. Its logic thresholds (VINH ≥5V, VINL ≤0.8V) and analog performance (RON, leakage, switching speed) are characterized only for +12V and +15V supplies. For low-voltage applications, Maxim recommends the pin-compatible MAX391 family - using +5V supply with degraded RON and higher leakage compared to MAX4591CSE.
Is the MAX4591CSE RoHS compliant and lead-free?
Yes, the MAX4591CSE is RoHS compliant and lead-free. Per Maxim's packaging documentation, the "CSE" suffix denotes a 16-pin narrow SO package with lead-free (Pb-free) finish and halogen-free molding compound. The device meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards.
