Product details
Overview
MAX4590EWE from Maxim Integrated is a dual normally open (NO) SPST 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 up to ±10V. It delivers matched on-resistance (≤0.25Ω), flat on-resistance (≤0.3Ω), and <2.5nA off-leakage at +85°C - ideal for precision test equipment switching paths.
For engineers reviewing the MAX4590EWE datasheet, MAX4590EWE pinout, MAX4590EWE application, or MAX4590EWE equivalent, key selection criteria include guaranteed RON matching across channels, TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), and -65dB crosstalk performance in high-density analog routing.
Technical Context
The MAX4590EWE implements a dual-channel, normally open SPST topology using enhanced CMOS process technology to achieve low distortion and minimal charge injection (40pC typical). Its control architecture accepts independent digital inputs (IN1/IN2) with defined logic thresholds, enabling direct interface to +5V logic without level shifting when VL = +5V.
It supports both single- and dual-supply configurations with full rail-to-rail analog signal swing capability (VCOM, VNO = V− to V+). Internal ESD protection exceeds 2kV per Method 3015.7, and all analog terminals are clamped by internal diodes to prevent damage from overvoltage transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal voltage drop and power loss in signal path at ±15V supplies |
| RON Match | 0.25Ω max - enables precise channel-to-channel gain/attenuation matching in differential or multiplexed systems |
| RON Flatness | 0.3Ω max - maintains consistent insertion loss across full ±10V analog input range |
| Off-Leakage Current | 2.5nA max at +85°C - preserves signal integrity in high-impedance sensor or reference circuits |
| Crosstalk | -65dB - suppresses inter-channel interference in multi-signal test or communication routing |
| Turn-On/Off Time | 150ns/200ns typical - supports fast switching in automated test sequencing and data acquisition |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility with +5V or +12V logic supplies |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - accommodates industrial, telecom, and legacy test equipment rails |
Pinout & Package
MAX4590EWE is housed in a 16-pin Wide SO (SOIC-W) package, 7.6mm × 10.3mm body, 1.27mm lead pitch, JEDEC MS-013 compliant. Pin 1 is top-left corner (notch side), with GND at Pin 5 and V+ at Pin 13.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Active-high logic: high = NO1/NO2 closed; compatible with +5V TTL/CMOS levels |
| COM1, COM2 | Analog common terminals | Signal entry points - connect to source or load depending on routing topology |
| NO1, NO2 | Normally open switch outputs | Only conduct when respective INx is high; isolated otherwise - no internal connection to NC |
| V+, V- | Analog supply rails | Define analog signal range; V- tied to GND for single-supply operation |
| VL | Logic supply reference | Bias for internal logic circuitry; typically +5V, independent of analog supply voltages |
| GND | Ground reference | Common return for logic and analog sections - critical for noise isolation in mixed-signal layouts |
| NC (Pins 1,3,6,8,10,15) | No-connect terminals | Not internally connected; recommended to tie to GND or low-impedance node to improve off-isolation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V− to V+ swing - eliminates clipping in ±15V instrumentation front-ends |
| Guaranteed RON match & flatness | Ensures ≤0.25Ω channel mismatch and ≤0.3Ω variation over ±10V - critical for precision gain-setting networks |
| TTL/CMOS-compatible logic inputs | Operates directly with standard +5V logic families without external level shifters or pull-ups |
| Low charge injection (40pC typ) | Minimizes transient glitches during switching - essential for sample-and-hold and ADC multiplexing |
| ESD protection >2kV | Meets Method 3015.7 - improves robustness in benchtop test environments with frequent probing |
| Wide supply flexibility | Single +4.5V–+36V or dual ±4.5V–±20V operation - simplifies design reuse across legacy and new platforms |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Higher RON (2.2Ω typ), wider temp range (-40°C to +125°C), SPI-controlled | Requires serial interface and external level translation for TTL logic; better for high-temp industrial control | Select when digital control bus integration and extended temperature operation outweigh RON penalty |
| TS5A3159DCKR | Lower voltage rating (+5.5V max), smaller SC70-6 package, 0.75Ω RON | Limited to low-voltage portable or battery-powered systems; not suitable for ±15V test gear | Select only for space-constrained, single-supply ≤5.5V designs where ultra-low RON is prioritized |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4590EWE uniquely balances wide supply range (+4.5V to +36V / ±4.5V to ±20V), sub-1.3Ω RON, and TTL/CMOS direct-drive - making it optimal for legacy and industrial test equipment where supply flexibility and logic simplicity are mandatory.

FAQ
What is the maximum analog signal voltage range supported by the MAX4590EWE?
The MAX4590EWE supports rail-to-rail analog signals from V− to V+, meaning ±10V with ±15V supplies or 0V to +10V with +12V single supply. Absolute maximum ratings allow V+ to GND up to +44V and V− to GND down to −44V, but operational signal range is bounded by the applied supply rails. The device maintains specified RON flatness (≤0.3Ω) across the full ±10V range.
Does the MAX4590EWE require external level-shifting for TTL/CMOS logic control?
No, the MAX4590EWE does not require external level-shifting. Its logic inputs have guaranteed thresholds of +0.8V (low) and +2.4V (high), ensuring direct compatibility with standard +5V TTL and CMOS logic families when VL = +5V. This eliminates the need for additional buffers or translators in most industrial and test equipment designs.
Can the MAX4590EWE operate from a single +5V supply?
No, the MAX4590EWE cannot operate from a single +5V supply. Its minimum single-supply voltage is +4.5V, but functional analog signal range requires sufficient headroom: with +5V V+, the usable analog swing is limited to approximately 0V–+3.5V due to internal voltage drops. For full rail-to-rail performance, use ≥+12V single supply or ±4.5V dual supplies.
How is the MAX4590EWE's off-isolation performance characterized?
The MAX4590EWE provides −53dB typical off-isolation (measured as 20·log10(VCOM/VNO) at 1MHz), ensuring strong signal rejection between open and closed paths. This specification is tested per Figure 4 in the datasheet using 0dBm input, 50Ω source/load, and applies across the full operating temperature range (−40°C to +85°C), supporting high-fidelity signal separation in multiplexed systems.
What is the thermal performance of the MAX4590EWE in its Wide SO package?
In its 16-pin Wide SO package, the MAX4590EWE has a thermal resistance θJA of 9.52mW/°C above +70°C, yielding 762mW maximum continuous power dissipation at TA = +70°C. Derating is linear above this point. Layout best practices include using thermal vias under the exposed pad (if present) and minimizing copper isolation around pins 4 (V−) and 13 (V+) to maintain stable analog performance under load.
