Product details
Overview
The MAX4590CAE+ 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+ datasheet, MAX4590CAE+ pinout, MAX4590CAE+ application, or MAX4590CAE+ equivalent, this page delivers verified electrical specs, truth-table-confirmed NO-switch behavior, package-specific thermal derating, ESD-rated control inputs, and real-world leakage performance at +85°C.
Technical Context
This device implements two independent CMOS transmission gates with TTL/CMOS-compatible logic thresholds (+0.8V low / +2.4V high), enabling direct interface with +5V or +12V digital controllers without level shifting. Each switch supports bidirectional rail-to-rail analog signals up to ±10V with guaranteed RON match ≤0.25Ω between channels.
It operates across industrial temperature range (–40°C to +85°C for E-grade; this part is C-grade: 0°C to +70°C), features internal ESD protection >2kV per Method 3015.7, and maintains flat on-resistance (≤0.3Ω variation) over its full signal range - critical for precision instrumentation and communication channel switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 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 balanced audio or ADC multiplexing. |
| RON flatness | 0.3Ω max - preserves linearity across full input voltage swing (±10V), reducing harmonic distortion in audio and sensor interfaces. |
| Off-leakage current | 2.5nA max at +85°C - prevents signal corruption in high-impedance circuits such as precision sensor front-ends or sample-and-hold stages. |
| Supply range | +4.5V to +36V single or ±4.5V to ±20V dual - supports wide-range industrial power rails and legacy ±15V systems without external regulators. |
| Logic compatibility | TTL/CMOS thresholds (+0.8V low / +2.4V high) - allows direct drive from microcontrollers, FPGAs, or logic families operating at +5V or +12V. |
| Turn-on/off time | 150ns / 200ns typical - enables fast channel switching in automated test systems and data acquisition at ≥1MHz sampling rates. |
Pinout & Package
MAX4590CAE+ uses a 16-pin SSOP (Shrink Small Outline Package) with 0.635mm lead pitch, 5.3mm body width, and JEDEC MO-150 compliance. Thermal derating is 7.1mW/°C above +70°C (571mW max at TA = +70°C).
| 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 high; floating when inactive. |
| 4 | V− | Negative analog supply - grounded for single-supply use; sets lower rail for bipolar signal handling. |
| 5 | GND | Analog/digital reference ground - shared return for supplies, logic, and signal paths; requires low-impedance layout. |
| 11, 14 | IN1, IN2 | Digital control inputs - active-high logic; drive NO1/NO2 closed when high (TTL/CMOS compatible). |
| 12 | VL | Logic supply input - powers internal gate drivers; typically +5V, independent of analog supply rails. |
| 13 | V+ | Positive analog supply - defines upper signal rail; supports up to +36V in single-supply mode. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from V− to V+, enabling full utilization of ±15V or +12V supply rails without clipping. |
| Guaranteed RON match | ≤0.25Ω difference between channels - eliminates gain mismatch in dual-path filtering or calibration circuits. |
| Low charge injection | 40pC typical - minimizes voltage glitch on sampled nodes, critical for precision ADC front-ends and sample-and-hold accuracy. |
| High off-isolation | –53dB typical at 1MHz - suppresses signal coupling between inactive channels in multi-channel test fixtures. |
| ESD protection | >2kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |

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); 1.3Ω RON; no dual-supply support; higher 35pC charge injection. | Best suited for +5V–+36V unipolar systems where dual-supply operation is unnecessary. | Select when system uses only positive rails and requires ADI's enhanced ESD rating (±4kV HBM). |
| TS5A3157DCKR | Lower voltage range (1.65V–5.5V); 0.75Ω RON; smaller SC70-6 package; no VL pin or dual-supply capability. | Ideal for portable, battery-powered signal routing where space and low-voltage operation are primary constraints. | Choose for compact, low-power designs requiring sub-1Ω RON but unable to support ±15V or +36V supplies. |
Compared with ADG1419BRUZ and TS5A3157DCKR, the MAX4590CAE+ uniquely supports true bipolar operation (±4.5V to ±20V), includes dedicated VL logic supply for mixed-rail control, and guarantees RON flatness ≤0.3Ω - making it the only option among the three qualified for precision rail-to-rail AC-coupled instrumentation.

FAQ
What is the maximum continuous current rating for each switch in the MAX4590CAE+?
The MAX4590CAE+ supports ±200mA continuous current per switch (COM/NO path). This rating applies across the full operating temperature range and supply conditions specified in the Absolute Maximum Ratings table. Exceeding this current may cause thermal overstress or parametric shift. The MAX4590CAE+ also allows ±300mA peak current (1ms pulse, 10% duty cycle) for transient loads such as relay coil discharge suppression.
Does the MAX4590CAE+ require external pull-up or pull-down resistors on its IN1 and IN2 pins?
No, the MAX4590CAE+ does not require external pull-up or pull-down resistors on IN1 or IN2. Its TTL/CMOS-compatible logic thresholds (+0.8V low, +2.4V high) ensure reliable switching with standard digital outputs. However, if left floating, inputs may assume indeterminate states - so tie unused control lines to GND or VL via 10kΩ resistors in production designs to prevent noise-induced switching.
Can the MAX4590CAE+ operate with V+ = +12V and V− = GND while still achieving rail-to-rail signal handling?
Yes, the MAX4590CAE+ supports single-supply operation with V+ = +12V and V− = GND, and maintains rail-to-rail signal handling from 0V to +12V. In this configuration, analog signals on COM/NO pins can swing fully between the supply rails. The device's guaranteed RON flatness (≤0.3Ω) and low leakage (<0.5nA typical) remain valid across this range, as confirmed in the Single-Supply Electrical Characteristics table.
What is the purpose of the VL pin on the MAX4590CAE+, and what voltage should it be set to?
The VL pin on the MAX4590CAE+ supplies power to the internal logic circuitry and level translators. It must be connected to a stable +5V supply - independent of V+ and V− - to ensure correct interpretation of TTL/CMOS input thresholds. Operating VL outside 4.5V–5.5V risks incorrect switching behavior or increased input current. The MAX4590CAE+ datasheet specifies VL = +5V for all performance characterization.
How does the MAX4590CAE+ compare to the MAX4580CAE+ in terms of switch configuration and control logic?
The MAX4590CAE+ contains two normally open (NO) SPST switches, closing when IN1 or IN2 is high. In contrast, the MAX4580CAE+ contains two normally closed (NC) switches, opening when IN1 or IN2 is high. Their pinouts differ: MAX4590CAE+ connects NO1/NO2 to pins 9/16, while MAX4580CAE+ places NC1/NC2 there. Both share identical RON, supply ranges, and timing - but their truth tables are logical inverses, requiring firmware or schematic changes for direct substitution.
