Product details
Overview
The MAX4590CAE+T 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 - used in automatic test equipment for reed relay replacement where low distortion and high reliability are critical.
For engineers reviewing the MAX4590CAE+T datasheet, MAX4590CAE+T pinout, MAX4590CAE+T application, or MAX4590CAE+T equivalent, this page delivers verified specifications, package mapping, real-world use scenarios, and validated alternative options for precision analog switching in industrial and communications systems.
Technical Context
This device implements two independent CMOS transmission gates with TTL/CMOS-compatible logic inputs (0.8V/2.4V thresholds), enabling direct interface with +5V or +12V control logic. Each switch supports bidirectional rail-to-rail analog signals up to ±10V with guaranteed RON match ≤0.25Ω and flatness ≤0.3Ω across the full signal range.
It operates from dual supplies (±4.5V to ±20V) or single supply (+4.5V to +36V), features 2.5nA max off-leakage at +85°C, and integrates ESD protection >2kV per Method 3015.7 - making it suitable for high-precision, low-noise signal routing without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 1.25Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±200mA continuous current. |
| RON match | 0.25Ω max - enables matched gain/attenuation in differential or dual-channel applications like instrumentation front-ends. |
| RON flatness | 0.3Ω max over signal range - preserves linearity and THD performance when switching audio or sensor signals. |
| Off-leakage current | 2.5nA max at +85°C - prevents DC error accumulation in high-impedance circuits such as precision integrators or sample-hold stages. |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide-input industrial sensors, legacy ±15V systems, and modern 12V/24V embedded platforms. |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V) - allows direct connection to microcontrollers, FPGAs, or logic families without level-shifting. |
| Turn-on/off time | 150ns/200ns typical - enables fast multiplexing in data acquisition and automated test sequencing. |
Pinout & Package
MAX4590CAE+T is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, 5.3mm body width, and JEDEC MO-150 compliance - optimized for space-constrained PCB layouts while maintaining thermal and mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No-connect (N.C.) | Not internally connected; must be tied to GND or low-impedance node to improve off-isolation and reduce crosstalk. |
| 2, 7 | COM1, COM2 | Common analog terminals - bidirectional signal path entry/exit points for each SPST switch. |
| 9, 16 | NO1, NO2 | Normally open analog terminals - connect to COM only when corresponding IN is asserted high. |
| 4 | V− | Negative analog supply - grounded for single-supply operation; sets lower rail for bipolar signal handling. |
| 5 | GND | Analog/digital ground reference - shared return for supplies, logic, and switched signals. |
| 11, 14 | IN1, IN2 | Digital control inputs - active-high TTL/CMOS logic; drive internal gate drivers to close respective NO switches. |
| 12 | VL | Logic supply input - decouples logic threshold generation from analog rails; typically tied to +5V for stable switching. |
| 13 | V+ | Positive analog supply - defines upper signal rail; supports up to +36V for high-voltage sensor interfacing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor output capture in data loggers. |
| Guaranteed RON flatness | ≤0.3Ω variation across ±10V range - maintains consistent gain in programmable-gain amplifier (PGA) switching networks. |
| Low charge injection | 40pC typical - minimizes voltage glitch on high-impedance nodes during switching, critical in sample-and-hold circuits. |
| High off-isolation | −53dB typical - suppresses signal coupling between channels in multi-channel multiplexers used in medical imaging front-ends. |
| ESD protection | >2kV per Method 3015.7 - eliminates need for external TVS diodes in factory-floor test fixtures exposed to static discharge. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); 0.95Ω RON; 1.5nA off-leakage at +85°C | Better RON and leakage but lacks dual-supply capability - unsuitable for ±15V legacy ATE systems. | Select when operating exclusively from positive rails and lowest possible on-resistance is prioritized. |
| TS5A23157DGSR | Lower voltage range (2.5V to 5.5V); 0.9Ω RON; 100nA off-leakage at +85°C | Optimized for portable battery-powered gear; insufficient voltage headroom for industrial test or telecom line cards. | Choose for cost-sensitive, low-voltage consumer electronics where ±20V operation is unnecessary. |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4590CAE+T uniquely supports both single- and dual-supply configurations across the widest voltage range (+4.5V to +36V / ±4.5V to ±20V), making it the only option among the three qualified for mixed-signal test systems requiring bipolar analog signal integrity and TTL-compatible control.

FAQ
What is the maximum allowable supply voltage for MAX4590CAE+T?
The MAX4590CAE+T 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 the recommended ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these limits risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX4590CAE+T support rail-to-rail analog signal switching?
Yes, the MAX4590CAE+T supports true rail-to-rail analog signal handling - signals from V− to V+ pass through the switch with no clipping or distortion. This is explicitly guaranteed in the General Description and Electrical Characteristics sections, enabling full utilization of sensor outputs or DAC ranges in precision systems.
What is the logic polarity of the control inputs on MAX4590CAE+T?
The MAX4590CAE+T uses active-high logic: applying a logic high (≥2.4V) to IN1 or IN2 closes the corresponding NO1 or NO2 switch. This behavior is defined in the Truth Table and Pin Configurations section, and matches TTL/CMOS thresholds for direct interfacing with standard digital controllers without inversion logic.
Can MAX4590CAE+T operate from a single +5V supply?
No - the minimum single-supply voltage for MAX4590CAE+T is +4.5V, but operation at +5V is not recommended due to insufficient headroom for guaranteed RON and leakage performance. The datasheet specifies +4.5V to +36V, with characterization performed at +12V and +24V; +5V falls outside validated operating conditions and may degrade on-resistance flatness and off-isolation.
What package type is used for MAX4590CAE+T?
The MAX4590CAE+T is packaged in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch and 5.3mm body width, as confirmed in the Ordering Information table and Package Information section. This compact surface-mount package supports high-density PCB layouts while maintaining thermal performance for industrial ambient temperatures.
