Product details
Overview
MAX392EUE+ from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in instrumentation, data acquisition, and audio applications. It features 100Ω on-resistance (typ), 5nA max off-leakage at +25°C, ±15V dual-supply operation, and guaranteed 40Ω channel-to-channel on-resistance matching across temperature.
For engineers reviewing the MAX392EUE+ datasheet, MAX392EUE+ pinout, MAX392EUE+ application, or MAX392EUE+ equivalent, this device is selected for high-accuracy multiplexing where low charge injection (±5pC typ), minimal THD (<0.002%), and rail-to-rail analog signal handling are critical in medical sensors, automated test equipment, and precision ADC front-ends.
Technical Context
The MAX392EUE+ implements four independent single-pole single-throw (SPST) switches using complementary MOSFET architecture with matched P- and N-channel devices per channel. Its control logic accepts TTL/CMOS-compatible inputs referenced to V+, enabling direct interfacing with microcontrollers without level-shifting.
Each switch operates over full analog signal range from V– to V+, supporting ±15V dual supplies or +12V single supply. The device guarantees monotonic on-resistance vs. common-mode voltage and maintains <1% on-resistance flatness across its specified analog input range, ensuring minimal gain error in precision gain-setting networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher RON (1.8Ω typ), lower leakage (1pA), but requires external VDD/VSS decoupling and lacks guaranteed RON flatness spec | Better for ultra-low-leakage picoampere current measurement; unsuitable where RON flatness impacts gain accuracy | Select ADG1414BRUZ only when sub-pA leakage dominates design priority over gain linearity |
| TS5A3157DCUR | Single-channel, lower voltage (5.5V max), higher RON (6Ω), no dual-supply support | Limited to low-voltage consumer audio; cannot replace MAX392EUE+ in ±15V industrial or medical systems | Use TS5A3157DCUR only in cost-sensitive, single-channel, 3.3V/5V portable designs |
Compared with ADG1414BRUZ and TS5A3157DCUR, the MAX392EUE+ uniquely delivers guaranteed rail-to-rail ±15V operation, 40Ω RON matching, and monotonic RON vs. VCOM - making it irreplaceable in precision multiplexed instrumentation where gain stability and signal fidelity are non-negotiable.

FAQ
What is the maximum supply voltage rating for MAX392EUE+?
The MAX392EUE+ supports dual-supply operation from ±4.5V to ±20V. Its absolute maximum ratings specify V+ to V– ≤ 40V, with V+ ≤ +20V and V– ≥ –20V. Exceeding these limits risks permanent damage. For reliable operation in precision systems, use ±15V supplies as specified in the MAX392EUE+ datasheet and ensure proper decoupling with 0.1μF ceramic capacitors at each supply pin.
Does MAX392EUE+ support single-supply operation?
Yes, MAX392EUE+ supports single-supply operation with V– grounded (0V) and V+ ranging from +4.5V to +20V. In this configuration, the analog signal range extends from 0V to V+, enabling compatibility with microcontroller-based systems. However, rail-to-rail performance and guaranteed RON flatness are specified only for dual-supply conditions per the MAX392EUE+ datasheet.
How does charge injection affect system performance in MAX392EUE+ applications?
MAX392EUE+ exhibits ±5pC typical charge injection, which causes a voltage step at the output when switching. In high-impedance sample-and-hold or integrator circuits, this can induce settling errors. To mitigate, use low-impedance source drivers (<1kΩ) and add small hold capacitors (≥100pF) at the COM node. The MAX392EUE+ datasheet confirms this behavior is consistent and repeatable across temperature.
Is MAX392EUE+ pin-compatible with other devices in the MAX39x family?
MAX392EUE+ shares identical pinout and package (16-pin TSSOP) with MAX391, MAX393, and MAX394, differing only in channel count and logic polarity. MAX391 is dual SPST, MAX392 is quad SPST (as with MAX392EUE+), MAX393 is dual SPDT, and MAX394 is quad SPDT. This allows drop-in replacement within the same footprint when channel topology matches the design requirement.
What is the guaranteed on-resistance matching specification for MAX392EUE+?
MAX392EUE+ guarantees ≤40Ω maximum difference in on-resistance between any two channels across temperature (–40°C to +85°C) and supply conditions. This is measured at VCOM = 0V, V+ = +15V, V– = –15V, and is critical for maintaining channel-to-channel gain consistency in multiplexed instrumentation. The MAX392EUE+ datasheet provides worst-case values in the Electrical Characteristics table under "RON Matching".
