Product details
Overview
The MAX4590CWE from Maxim Integrated is a dual SPST normally open (NO) CMOS analog switch with 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - used in automatic test equipment for reed relay replacement where low distortion and high reliability are critical.
For engineers reviewing the MAX4590CWE datasheet, MAX4590CWE pinout, MAX4590CWE application, or MAX4590CWE equivalent, key selection considerations include guaranteed RON match (≤0.25Ω), flat on-resistance (≤0.3Ω over signal range), TTL/CMOS-compatible logic thresholds, off-leakage ≤2.5nA at +85°C, and SOIC-Wide (16-pin) package compatibility.
Technical Context
The MAX4590CWE implements two independent normally open analog switches using enhanced CMOS process technology, supporting bidirectional rail-to-rail analog signals up to ±10V with minimal distortion. Its control logic accepts TTL/CMOS levels across full supply ranges, eliminating level-shifting requirements when operating from ±15V or +12V supplies.
Each switch features matched on-resistance (ΔRON ≤ 0.25Ω), flat on-resistance (RFLAT(ON) ≤ 0.3Ω), and guaranteed ESD protection >2kV per Method 3015.7. Dynamic performance includes tON = 150ns and tOFF = 200ns (typical, VCOM = +10V, RL = 100Ω, CL = 35pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.25Ω max - ensures minimal voltage drop and power loss in precision signal routing paths |
| RON Match Between Channels | 0.25Ω max - enables accurate differential or ratiometric measurements without calibration |
| RON Flatness | 0.3Ω max over ±10V signal range - preserves linearity in audio, instrumentation, and data acquisition |
| Off-Leakage Current | 2.5nA max at +85°C - prevents signal corruption in high-impedance sensor interfaces |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and telecom voltage rails |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) at +12V or ±15V - eliminates external level shifters |
| Turn-On/Off Time | 150ns / 200ns typical - suitable for medium-speed multiplexing and channel switching |
Pinout & Package
MAX4590CWE is housed in a 16-pin Wide SO (SOIC-W) package (7.6mm × 10.3mm body, 1.27mm pitch), RoHS-compliant and rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No-connect (N.C.) | Not internally connected; tie to GND or low-impedance node to improve isolation |
| 2, 7 | COM1, COM2 | Common analog terminals - bidirectional signal path entry/exit points for each switch |
| 9, 16 | NO1, NO2 | Normally open analog terminals - connect to COM only when corresponding IN is high |
| 4 | V− | Negative analog supply - grounded for single-supply operation; sets lower signal rail |
| 5 | GND | Digital/analog reference ground - separate grounding recommended for noise-sensitive layouts |
| 11, 14 | IN1, IN2 | Digital control inputs - active-high logic; drive with 0.8V/2.4V thresholds for TTL/CMOS compatibility |
| 12 | VL | Logic supply input - decouples logic threshold generation from analog supplies; typically +5V |
| 13 | V+ | Positive analog supply - defines upper signal rail; supports up to +36V or +20V (dual) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor and DAC outputs |
| Guaranteed RON flatness | ≤0.3Ω variation across ±10V range - maintains gain accuracy in programmable-gain amplifiers and attenuators |
| Low charge injection | 40pC typical - minimizes transient glitches in sample-and-hold and ADC front-end circuits |
| High off-isolation | −53dB typical at 1MHz - suppresses crosstalk between channels in multi-channel test systems |
| ESD protection | >2kV per Method 3015.7 - improves robustness during board handling and system integration |
Applications
| Reed Relay Replacement | Automatic Test Equipment (ATE) |
|---|---|
Use Scenario: Replacing electromechanical relays in semiconductor wafer probers and PCB functional testers where cycle life and speed limit mechanical solutions. IC Role / Device Role / Timing Role: Dual SPST NO switch routing analog stimulus/sense paths under digital control with sub-200ns switching. Use Value: 100M+ cycle lifetime vs. <1M for reeds, no contact bounce, and 10× faster settling enable higher test throughput. | Use Scenario: Signal routing in modular ATE backplanes connecting DUT interfaces to source-measure units (SMUs) and digitizers. IC Role / Device Role / Timing Role: Precision analog path selector with matched RON and low leakage to preserve measurement integrity across channels. Use Value: ≤0.25Ω RON match eliminates inter-channel gain error; ≤2.5nA off-leakage prevents bias current errors in picoamp-level SMU measurements. |

Use Scenario: Selecting between multiple codec channels or hybrid circuits in VoIP gateways and baseband signal conditioning modules. IC Role / Device Role / Timing Role: Low-distortion analog switch enabling transparent audio path selection without added THD or noise. Use Value: 1.25Ω RON and rail-to-rail support maintain SNR >90dB across 0–4kHz voice band; flat RON avoids frequency-dependent attenuation. | Use Scenario: Supervisory signal routing (ring detect, battery feed, hookswitch) in enterprise telephony line cards. IC Role / Device Role / Timing Role: High-voltage-tolerant analog switch isolating control logic from ±48V tip/ring lines via transformer-coupled interface. Use Value: ±20V dual-supply rating allows direct connection to line interface ICs; >2kV ESD protection withstands field-induced transients on telephone wiring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); RON = 1.3Ω max; no VL pin; requires external logic level translation for ±15V systems | Best suited for new designs with single-supply architecture and space-constrained layouts (16-TSSOP) | Select when simplifying supply architecture outweighs need for dual-supply flexibility and guaranteed RON match |
| TS5A23159DRCR | Lower voltage range (2.5V to 5.5V); RON = 0.9Ω max; no dual-supply support; 10-pin WSON package | Ideal for portable, battery-powered instrumentation with low-voltage analog front ends | Choose for cost-sensitive, low-power applications where ±15V operation and high-temperature leakage specs are not required |
Compared with ADG1419BRUZ and TS5A23159DRCR, the MAX4590CWE uniquely supports both single- and dual-supply configurations with guaranteed RON matching and flatness - making it the preferred choice for legacy test equipment upgrades and mixed-voltage industrial systems requiring signal integrity across wide temperature and voltage ranges.

FAQ
What is the maximum allowable supply voltage for MAX4590CWE?
The MAX4590CWE supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within specified ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these may cause permanent damage, and the device is not characterized beyond ±20V or +36V.
Does MAX4590CWE require a separate logic supply voltage?
Yes, the MAX4590CWE requires VL (pin 12) to be supplied - typically +5V - to establish TTL/CMOS-compatible logic thresholds independent of analog supplies. This decoupling ensures stable switching behavior even when V+ and V− vary widely, and VL must remain within −0.3V to (V+ + 0.3V).
Can MAX4590CWE operate with only a single positive supply?
Yes, the MAX4590CWE operates with a single +4.5V to +36V supply by connecting V− (pin 4) to GND. In this configuration, analog signals swing from GND to V+, and the device maintains rail-to-rail capability, 1.25Ω max RON, and 2.5nA max off-leakage at +85°C - verified per Electrical Characteristics table for single-supply conditions.
What is the function of the N.C. pins on MAX4590CWE?
The N.C. pins (1, 3, 6, 8, 10, 15) on MAX4590CWE are not internally connected. They must be tied to GND or a low-impedance node to minimize capacitive coupling and improve on/off isolation - especially critical in high-density PCB layouts where adjacent traces carry sensitive analog or fast-switching digital signals.
How does MAX4590CWE achieve rail-to-rail signal handling?
The MAX4590CWE achieves rail-to-rail signal handling through its enhanced CMOS process and charge-pump-assisted gate drive, allowing analog signals at COM and NO terminals to swing continuously from V− to V+ without clipping or increased distortion - confirmed by characterization across ±10V signal ranges in both single- and dual-supply modes per Typical Operating Characteristics plots.
