Product details
Overview
MAX392CSE from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in instrumentation, data acquisition, and communication systems. It features 100Ω on-resistance (typ), ±15V dual-supply operation, <1pC charge injection, and 0.5nA max off-leakage at +25°C - enabling accurate multiplexing of sensor signals and audio paths.
For engineers reviewing the MAX392CSE datasheet, MAX392CSE pinout, MAX392CSE application, or MAX392CSE equivalent, key selection criteria include guaranteed RON flatness over ±10V signal range, rail-to-rail analog switching capability, thermal stability across –40°C to +85°C, and compatibility with 5V/3V logic control interfaces.
Technical Context
The MAX392CSE implements four independent single-pole single-throw (SPST) switches using enhancement-mode p-channel and n-channel MOSFETs in series, achieving symmetrical conduction and minimal signal-dependent on-resistance variation. Its architecture supports both dual-supply (±5V to ±15V) and single-supply (10V to 30V) configurations without performance degradation.
Switching is controlled by TTL/CMOS-compatible digital inputs referenced to VSS, with guaranteed turn-on/turn-off times of 125ns/75ns (max) at V+ = +15V, V− = −15V. The device maintains <0.02% THD+N at 1kHz under full-scale sine-wave conditions, confirming suitability for precision measurement front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 120Ω - ensures ≤0.1% gain error in 12-bit ADC input multiplexing at 1kΩ source impedance |
| RON flatness (max) | 5Ω - guarantees consistent channel matching for differential signal routing |
| Charge injection (max) | 1.5pC - limits settling error to <1LSB in 16-bit sampling systems with 10kΩ hold capacitor |
| Off-leakage (max) | 0.5nA at +25°C - enables ≥16-bit accuracy in high-impedance sensor interfaces (e.g., pH electrodes) |
| Bandwidth (–3dB) | 200MHz - supports video signal switching and fast pulse transmission without edge degradation |
| Supply range | ±5V to ±15V dual or 10V to 30V single - allows direct integration into industrial ±12V and telecom +24V systems |
| Logic compatibility | 3V/5V CMOS/TTL - eliminates level-shifter requirements when interfacing with microcontrollers and FPGAs |
Pinout & Package
MAX392CSE is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NO (Normally Open) | Switch output terminals - connect to load side; open-circuit when IN = LOW |
| 2, 6, 10, 14 | COM | Common analog path - bidirectional signal terminal shared with NO/NC |
| 3, 7, 11, 15 | IN | Digital control input - active HIGH enables switch closure (TTL/CMOS compatible) |
| 4 | V+ | Positive supply rail - must be ≥|V−| for symmetric operation; sets upper analog voltage limit |
| 12 | V− | Negative supply rail - establishes lower analog voltage limit and reference for logic threshold |
| 8 | GND | Logic ground - separate from analog return; critical for minimizing digital noise coupling |
Key Features
| Feature | Design Value |
|---|---|

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), but requires ≥±4.5V supplies; higher supply current (220μA vs. 100μA) | Better for low-voltage, high-speed applications; less suitable for legacy ±15V industrial systems | Select ADG1412BRUZ only if RON <2Ω is mandatory and supply rails are constrained to ±5V. |
| TS5A3157DCKR | Single-channel, 5V-only supply; much lower RON (0.75Ω), but limited to 5.5V max analog signal | Appropriate for consumer electronics and battery-powered devices; not viable for industrial ±10V signal routing | Choose TS5A3157DCKR for cost-sensitive, low-voltage PCB designs where quad-channel density is not required. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX392CSE uniquely balances wide supply range (±15V), quad-channel integration, and sub-pC charge injection - making it the only option qualified for high-accuracy, multi-sensor industrial data loggers operating from standard ±12V rails.

FAQ
What is the maximum analog signal voltage range supported by the MAX392CSE?
The MAX392CSE supports analog signals from V− to V+, with supply rails configurable from ±5V to ±15V dual or 10V to 30V single. When operated at ±15V, the MAX392CSE reliably switches signals across the full ±15V range without distortion or clipping - a key requirement for industrial process control and test equipment interfacing with ±10V sensors.
Does the MAX392CSE require external pull-up resistors on its digital control inputs?
No, the MAX392CSE does not require external pull-up resistors. Its IN pins accept standard TTL/CMOS logic levels (0.8V max LOW, 2.4V min HIGH) with internal threshold referencing to VSS, and exhibit typical input leakage of ±10nA. This allows direct connection to microcontroller GPIOs or FPGA outputs without additional biasing components - simplifying layout and reducing BOM count for the MAX392CSE.
How does charge injection of the MAX392CSE affect sampling accuracy in ADC applications?
The MAX392CSE specifies a maximum charge injection of 1.5pC, which - when coupled with a 10nF sample capacitor - produces a worst-case voltage glitch of 150μV. In a 16-bit system with 10V full-scale range (152.6μV/LSB), this corresponds to <1LSB error, ensuring the MAX392CSE maintains monotonicity and accuracy without requiring additional settling time or correction algorithms in precision ADC front-ends.
Can the MAX392CSE operate from a single +12V supply while switching ±5V analog signals?
No. The MAX392CSE cannot switch signals beyond the supply rails. With a single +12V supply (V+ = +12V, V− = GND), the analog signal range is limited to 0V to +12V. To switch ±5V signals, the device must be powered from dual supplies (e.g., V+ = +5.5V, V− = −5.5V) to ensure the full ±5V range lies within V− to V+. This rail constraint is fundamental to the MAX392CSE's architecture and is explicitly defined in its absolute maximum ratings.
Is the MAX392CSE pin-compatible with other devices in the MAX39x family?
Yes, the MAX392CSE shares identical pinout and footprint with the MAX391CSE (single SPST), MAX393CSE (dual SPST), and MAX394CSE (quad SPDT) in the same SOIC-16 package. This allows hardware reuse across designs requiring different channel counts or switch topologies - for example, upgrading from MAX391CSE to MAX392CSE requires no PCB changes, only firmware updates to manage the additional control lines for the MAX392CSE.
