Product details
Overview
MAX392EUE+T from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in instrumentation, data acquisition, and audio systems. It features 100Ω on-resistance (typ), ±15V dual-supply operation, 1pC typical charge injection, and 0.5nA max off-leakage at +25°C - enabling high-fidelity switching of ±10V analog signals in 16-bit data converter interfaces.
For engineers reviewing the MAX392EUE+T datasheet, MAX392EUE+T pinout, MAX392EUE+T application, or MAX392EUE+T equivalent, key selection criteria include guaranteed RON flatness over signal range, sub-pC charge injection for minimal settling error, rail-to-rail analog signal handling with ±15V supplies, and TSSOP-16 package compatibility with space-constrained mixed-signal PCB layouts.
Technical Context
The MAX392EUE+T implements four independent, normally-open analog switches using enhanced n-channel/p-channel MOSFET pairs. Its architecture ensures matched on-resistance across channels and temperature, with RON variation ≤3Ω from -4.5V to +4.5V VCOM at ±15V supplies. Charge injection is minimized via balanced gate drive and optimized channel geometry.
Switching is controlled by TTL/CMOS-compatible digital inputs referenced to V+/V−, supporting direct interfacing with microcontrollers and FPGAs. The device operates over -40°C to +85°C and maintains guaranteed performance across its full ±15V supply range without requiring external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON | 100Ω typical at ±15V supplies - enables <1 LSB gain error in 16-bit SAR ADC front-ends with 10kΩ source impedance |
| RON Flatness | ≤3Ω over ±4.5V signal range - preserves linearity in precision sensor signal conditioning paths |
| Charge Injection | 1pC typical - limits voltage glitch to <100μV on 10nF sampling capacitors, critical for fast-settling data acquisition |
| Off-Leakage Current | 0.5nA max at +25°C - prevents >1LSB offset drift in high-impedance pH or thermocouple measurement circuits |
| Bandwidth | 30MHz - supports switching of audio band and medium-speed control signals without attenuation |
| Supply Range | ±4.5V to ±20V dual supply - accommodates industrial ±10V signal standards and legacy ±15V systems |

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), wider supply range (±5V to ±22V), but larger 20-lead TSSOP package | Better suited for high-voltage industrial switching where RON tolerance is less critical than voltage margin | Select ADG1414BRUZ when ±22V operation or lower on-resistance drift vs. temperature is required |
| TS5A3157DCKR | Single-supply only (1.65V–5.5V), much lower RON (0.75Ω), but limited to 5.5V max analog signal | Targeted at portable battery-powered systems with 3.3V logic and low-voltage analog signals | Select TS5A3157DCKR for cost-sensitive consumer electronics where ±15V capability is unnecessary |
Compared with ADG1414BRUZ and TS5A3157DCKR, the MAX392EUE+T uniquely balances ±15V dual-supply operation, 100Ω RON, and 1pC charge injection in a compact TSSOP-16 - making it optimal for industrial data acquisition where signal fidelity, voltage range, and board space are simultaneously constrained.

FAQ
What is the maximum analog signal voltage range supported by the MAX392EUE+T?
The MAX392EUE+T supports analog signals from V− +1V to V+ −1V. With ±15V supplies, this delivers a usable signal range of ±14V - sufficient for full-scale operation with standard ±10V industrial sensor outputs and test equipment signal levels. Operation outside this range risks increased distortion or latch-up.
Does the MAX392EUE+T require external pull-up or pull-down resistors on its digital control inputs?
No, the MAX392EUE+T does not require external pull-up or pull-down resistors. Its digital inputs have TTL/CMOS-compatible thresholds referenced to the V+/V− rails, with guaranteed recognition of logic HIGH above V− +2.4V and logic LOW below V− +0.8V. This allows direct connection to 3.3V or 5V microcontrollers without level-shifting circuitry.
How does charge injection in the MAX392EUE+T affect sampling accuracy in ADC applications?
With 1pC typical charge injection, the MAX392EUE+T introduces <100μV of voltage glitch on a 10nF sampling capacitor - well within the 1LSB error budget of 16-bit (≈15μV) and even 18-bit (≈3.7μV) ADCs when combined with proper layout and settling time. This enables accurate multiplexed sampling without additional zero-crossing detection or correlated double sampling.
Can the MAX392EUE+T operate from a single +12V supply?
No, the MAX392EUE+T requires dual supplies (V+ and V−) and cannot operate from a single-ended supply. Its architecture relies on symmetric positive and negative rails to bias internal MOSFETs correctly. For single-supply applications, consider the MAX391 series (e.g., MAX391ESE+) which is pin-compatible but rated for 0V to +12V operation.
What thermal considerations apply to the MAX392EUE+T in continuous operation?
The MAX392EUE+T's exposed thermal pad must be soldered to a minimum 100mm² copper pour on the PCB to maintain junction temperature ≤+125°C at +85°C ambient. With all four switches conducting 10mA at 100Ω RON, power dissipation reaches 40mW - manageable with the TSSOP-16 thermal design, but derating is required above +70°C ambient without adequate copper area.
