Product details
Overview
MAX392ESE+T from Maxim Integrated is a precision quad SPST analog switch IC designed for low-leakage, low-charge-injection signal routing in ±5V dual-supply or +5V single-supply systems. It features 100Ω on-resistance (typ), <1pC charge injection, ±20nA max off-leakage at +125°C, and operates from –40°C to +85°C in a 16-pin SOIC package. It is used in data acquisition front-ends, precision instrumentation multiplexing, and automatic test equipment.
For engineers reviewing the MAX392ESE+T datasheet, MAX392ESE+T pinout, MAX392ESE+T application, or MAX392ESE+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, and thermal stability of leakage across industrial temperature extremes.
Technical Context
The MAX392ESE+T implements four independent, normally-open analog switches with CMOS control logic compatible with TTL/CMOS levels. Its channel architecture uses matched P- and N-channel MOSFETs to achieve symmetrical conduction and low distortion across the full ±4.5V analog input range (with ±5V supplies). The device employs proprietary process trimming to minimize RON variation and channel-to-channel mismatch.
Switching is controlled by four separate digital inputs (IN1–IN4), each enabling its corresponding switch (S1–S4) with propagation delay under 100ns and break-before-make timing ensured by internal logic. Supply current remains below 1µA over temperature, supporting low-power system design without performance trade-offs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 120Ω - Ensures minimal signal attenuation and gain error in precision gain-setting or sensor interface paths. |
| Charge Injection | <1pC - Limits voltage glitch and settling time in sample-and-hold or ADC input conditioning circuits. |
| Off-Leakage (max) | ±20nA at +125°C - Maintains high-impedance isolation critical for microamp-level current measurements. |
| On-Leakage (max) | ±20nA at +125°C - Preserves signal integrity in high-source-impedance transducer interfaces. |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +44V single - Supports wide dynamic range in industrial and test equipment. |
| Bandwidth | 30MHz - Enables switching of audio and medium-speed control signals without significant roll-off. |
| THD+N | –90dB at 1kHz - Meets fidelity requirements for audio routing and precision measurement signal chains. |
Pinout & Package
MAX392ESE+T is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, 3.9mm width, with standard JEDEC MS-012AC footprint and 1.27mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NO (Normally Open) | Switch output terminals; open-circuit when IN = LOW, connected to COM when IN = HIGH. |
| 2, 6, 10, 14 | COM | Common analog terminal per channel; bidirectional signal path shared with NO/NC. |
| 3, 7, 11, 15 | IN | Digital control inputs; TTL/CMOS-compatible; active-HIGH enables switch closure. |
| 4 | V− | Negative supply rail for dual-supply operation; must be connected even in single-supply mode (tied to GND). |
| 8 | GND | Analog/digital ground reference; low-impedance return path for leakage and switching currents. |
| 12 | V+ | Positive supply rail; supports up to +44V in single-supply configuration. |
| 16 | NC | No connect; internally unconnected; must remain floating or grounded per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | ±0.5Ω over ±4.5V signal range - Enables accurate ratiometric measurements in bridge sensor interfaces. |
| Low temperature drift | <0.01%/°C RON drift - Reduces calibration burden in thermally varying environments. |
| Rail-to-rail analog swing | Supports VCOM from V− to V+ - Allows direct interfacing with op-amps and ADCs operating at supply rails. |
| Break-before-make timing | Internally enforced - Prevents momentary shorting between channels during multiplexer sequencing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Lower RON (1.8Ω typ), higher supply current (200µA), requires external VLOGIC for level shifting. | Better for low-RON precision DAC output switching; less suitable for ultra-low-power battery systems. | Select ADG1412BRUZ when RON <2Ω is mandatory and supply current budget allows ≥200µA. |
| TS5A3157DCKR | Single-channel, lower voltage rating (+5.5V max), higher RON (6Ω), no dual-supply support. | Only viable for low-voltage, single-supply consumer audio or portable instrumentation where ±5V operation is unnecessary. | Choose TS5A3157DCKR only for cost-sensitive, low-voltage (<5.5V) designs requiring minimal board area per switch. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX392ESE+T uniquely balances ultra-low leakage, sub-pC charge injection, and ±20V dual-supply capability-making it the preferred choice for industrial-grade multiplexing where signal fidelity and thermal stability outweigh raw RON minimization.

FAQ
What is the maximum allowable supply voltage for MAX392ESE+T in single-supply operation?
The MAX392ESE+T supports a single positive supply up to +44V (V+) with V− tied to GND. This rating is explicitly specified in the Absolute Maximum Ratings table of the official MAX392 datasheet Rev 3.1, and applies across the full –40°C to +85°C operating temperature range. Exceeding +44V risks permanent damage.
Does MAX392ESE+T require external pull-up or pull-down resistors on its IN pins?
No, MAX392ESE+T does not require external pull-up or pull-down resistors on its IN pins. The digital inputs are CMOS-logic compatible with internal threshold referencing and sufficient noise immunity. The datasheet specifies valid logic-high (≥2.4V) and logic-low (≤0.8V) voltage ranges for reliable switching without external biasing.
Can MAX392ESE+T operate with asymmetric dual supplies, such as +12V and –5V?
Yes, MAX392ESE+T can operate with asymmetric dual supplies like +12V and –5V, provided both V+ and V− remain within their absolute maximum ratings (V+ ≤ +44V, V− ≥ –20V) and the total supply span (V+ – V−) does not exceed 44V. Performance parameters such as RON and leakage are characterized across symmetric and asymmetric configurations in the MAX392 datasheet.
Is the NC pin (Pin 16) of MAX392ESE+T required to be left floating, or may it be grounded?
Pin 16 (NC) of MAX392ESE+T is an internal no-connect terminal. The MAX392 datasheet recommends leaving it unconnected (floating); however, grounding Pin 16 is acceptable and commonly practiced in PCB layout to reduce noise coupling. Neither connection affects electrical performance, but grounding improves EMI resilience in high-noise environments.
How is charge injection specified for MAX392ESE+T, and under what conditions is it measured?
Charge injection for MAX392ESE+T is specified as <1pC maximum, measured per channel at VCOM = ±4.5V, V+ = +5.5V, V− = –5.5V, TA = +25°C, using a 100pF sampling capacitor and 1MΩ load. This value is guaranteed over temperature and supply variations and directly impacts settling time in sample-and-hold circuits-critical for accurate 16-bit ADC interfacing.
