Product details
Overview
MAX4590EWE+ from Maxim Integrated is a dual normally open (NO) SPST CMOS analog switch optimized for rail-to-rail signal routing in precision instrumentation and automated test equipment. It delivers 1.25Ω max on-resistance, 0.25Ω max channel-to-channel RON match, and 2.5nA max off-leakage at +85°C, enabling low-distortion switching of ±10V analog signals in reed relay replacement applications.
For engineers reviewing the MAX4590EWE+ datasheet, MAX4590EWE+ pinout, MAX4590EWE+ application, or MAX4590EWE+ equivalent, key selection criteria include single/dual-supply operation (+4.5V to +36V or ±4.5V to ±20V), TTL/CMOS-compatible logic thresholds, guaranteed RON flatness (0.3Ω max), ESD protection (>2kV), and wide-temperature performance (-40°C to +85°C).
Technical Context
The MAX4590EWE+ implements a dual independent SPST NO switch architecture with separate COM1/NO1 and COM2/NO2 signal paths. Each channel features matched on-resistance and flat RON over its full ±10V signal range, ensuring consistent gain and minimal THD in audio and data acquisition paths.
Control logic uses fixed-threshold TTL/CMOS-compatible inputs (0.8V low / 2.4V high) referenced to VL, supporting direct interface with +5V microcontrollers even under ±15V analog supply conditions. Internal protection diodes clamp input transients, while charge injection is limited to 40pC typical for minimal glitch-induced error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 1.25Ω max - ensures minimal voltage drop and power loss when switching ±10V signals at 10mA. |
| RON Match | 0.25Ω max - guarantees matched gain and phase response between channels in differential or dual-path systems. |
| RON Flatness | 0.3Ω max - maintains stable attenuation and linearity across full analog signal swing (±10V). |
| Off-Leakage Current | 2.5nA max at +85°C - preserves high-impedance node integrity in precision sensor front-ends and sample-hold circuits. |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, test, and battery-powered designs without level-shifting. |
| Logic Thresholds | +0.8V low / +2.4V high - enables direct interfacing with +5V CMOS/TTL controllers under all valid supply configurations. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field service without external protection. |
Pinout & Package
MAX4590EWE+ is housed in a 16-pin Wide SO (SOIC-W) package measuring 10.3mm × 7.6mm × 2.35mm, with gull-wing leads and 1.27mm pitch. The package is RoHS-compliant and rated for -40°C to +85°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 point to improve isolation performance. |
| 2, 7 | GND | Analog and digital ground reference; must be low-impedance for optimal noise rejection and leakage control. |
| 4 | V− | Negative analog supply input; connect to GND for single-supply operation (+4.5V to +36V). |
| 5 | GND | Secondary ground pin - use for star grounding or split-plane decoupling near V−/V+ pins. |
| 9, 16 | NO1, NO2 | Normally open analog outputs - conduct only when corresponding INx = high (TTL/CMOS logic). |
| 11, 14 | COM1, COM2 | Common analog inputs - accept rail-to-rail signals up to ±10V with minimal distortion. |
| 12 | VL | Logic supply input - powers internal control circuitry; typically +5V, independent of analog supply rails. |
| 13 | V+ | Positive analog supply input - sets upper signal limit; supports up to +36V or +20V (dual). |
| 1, 3, 6, 8, 10, 15 | N.C. | Unused pins - must not float; grounding improves off-isolation and reduces crosstalk. |
| IN1, IN2 | Digital Control Inputs | Active-high logic inputs - drive respective switches ON when ≥2.4V; compatible with +5V microcontrollers. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (±10V typical), eliminating level-shifting in bipolar front-ends. |

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 | 1.3Ω RON, ±15V supply, 16-TSSOP, but requires VL = V+ for logic interface. | Higher RON flatness (0.5Ω), no separate VL pin - less flexible in mixed-supply systems. | Prefer when using only ±15V supplies and needing higher ESD rating (4kV HBM). |
| TS5A23157DGSR | 0.9Ω RON, +1.65V to +5.5V single supply only, 10-pin VSSOP, no dual-supply support. | Lower voltage operation only; unsuitable for ±10V or >+5.5V signal routing. | Choose for battery-powered, low-voltage (<+5.5V) portable designs where size and RON are primary concerns. |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4590EWE+ uniquely supports independent logic/analog supplies, rail-to-rail ±10V signal handling, and guaranteed RON match - making it the preferred choice for industrial test and instrumentation where supply flexibility and channel matching are critical.

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+, with guaranteed operation up to ±10V when powered from ±15V supplies. Under single-supply conditions (+12V), it handles signals from 0V to +10V. Absolute maximum ratings allow V+ to +36V and V− to −44V, but signal swing remains constrained by supply rails and internal design limits. The MAX4590EWE+ datasheet specifies ±10V as the tested and guaranteed linear range for low-distortion performance.
Does the MAX4590EWE+ require external level-shifting when interfaced with a +3.3V microcontroller?
No, the MAX4590EWE+ does not require external level-shifting for +3.3V microcontrollers. Its logic inputs have fixed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and accept VL = +3.3V or +5V. When VL = +3.3V, a +3.3V GPIO high (≥2.4V) fully satisfies the IN1/IN2 high threshold, and a low (≤0.8V) ensures reliable OFF state. This native compatibility eliminates discrete level-shifters in mixed-voltage systems using the MAX4590EWE+.
How does the MAX4590EWE+ compare to mechanical relays in automated test equipment?
The MAX4590EWE+ replaces mechanical relays in ATE by offering 1.25Ω on-resistance, 2.5nA off-leakage at +85°C, and sub-200ns switching times - enabling faster test cycles, longer lifetime (>1 billion operations), smaller footprint, and lower power consumption. Unlike relays, it provides guaranteed RON match (0.25Ω max) and flatness (0.3Ω max), critical for precision calibration paths. The MAX4590EWE+ also eliminates contact bounce, wear-out, and coil drive complexity inherent in electromechanical solutions.
Can the MAX4590EWE+ operate with V+ = +24V and V− = GND while routing ±5V AC signals?
Yes, the MAX4590EWE+ can operate with V+ = +24V and V− = GND (single supply) while routing ±5V AC signals, provided the signal common-mode voltage stays within the device's specified input voltage range: (V− − 0.3V) to (V+ + 0.3V). With V− = 0V and V+ = +24V, the allowable range is −0.3V to +24.3V. A ±5V AC signal centered at 0V (i.e., swinging from −5V to +5V) falls fully within this window. The MAX4590EWE+ maintains rail-to-rail functionality and low distortion under these conditions.
What is the purpose of the VL pin on the MAX4590EWE+, and how should it be configured?
VL is the logic supply input that powers the internal digital control circuitry of the MAX4590EWE+. It must be connected to a stable +3.3V or +5V source - independent of V+ and V− - to ensure correct interpretation of IN1/IN2 logic levels. VL defines the reference for the 0.8V/2.4V input thresholds. Connecting VL to V+ is not recommended, as it risks exceeding absolute maximum ratings if V+ exceeds +5.5V. For reliable operation, VL should be decoupled with a 0.1µF capacitor close to the MAX4590EWE+ pin.
