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 audio systems. It features 100Ω on-resistance (typ), <5pC charge injection, ±15V dual-supply operation, and guaranteed 100Ω channel matching across all four switches - enabling accurate multiplexing of sensor signals in 16-bit ADC front-ends.
For engineers reviewing the MAX392CSE+ datasheet, MAX392CSE+ pinout, MAX392CSE+ application, or MAX392CSE+ equivalent, key selection criteria include its guaranteed RON flatness over ±10V signal range, sub-10nA leakage at +85°C, rail-to-rail analog signal handling, and SOIC-16 package compatibility with automated PCB assembly.
Technical Context
The MAX392CSE+ implements four independent, normally-open analog switches using enhanced n-channel DMOS technology. Each switch operates with matched RON (≤100Ω) and ultra-low charge injection (<5pC), ensuring minimal transient errors during switching of high-impedance sources like piezoelectric sensors or photodiode amplifiers.
It supports dual supplies from ±4.5V to ±20V or single supply from +10V to +44V, with logic-compatible control inputs (TTL/CMOS) referenced to VSS. The device guarantees monotonic RON vs. VCOM behavior and maintains ≤0.01% RON matching between channels at +25°C.
Key Specifications

|---|---|
| RON (max) | 100Ω - Ensures ≤0.05% gain error in 12-bit DAC output buffers driving 10kΩ loads. |
| Charge Injection | <5pC - Limits settling error to <1LSB in 16-bit, 100kSPS SAR ADC sample-and-hold stages. |
| Off-Leakage (max) | 10nA at +85°C - Maintains ≥100MΩ isolation for thermocouple cold-junction compensation circuits. |
| Supply Range | ±4.5V to ±20V dual or +10V to +44V single - Supports direct interface with industrial ±10V I/O standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Higher RON (1.8Ω typ), but lower charge injection (0.2pC); requires ±15V supplies only. | Better suited for ultra-low-distortion RF sampling; less tolerant of wide analog voltage swings. | Select when charge injection dominates error budget and supply rails are fixed at ±15V. |
| TS5A23159DCKR | Lower voltage rating (+5.5V max), higher RON (0.9Ω), but smaller SC-70-6 package. | Targeted at portable battery-powered systems; incompatible with industrial ±10V signal ranges. | Choose for space-constrained consumer electronics where rail-to-rail analog swing is not required. |
Compared with ADG1412BRUZ and TS5A23159DCKR, the MAX392CSE+ uniquely balances wide supply flexibility (±4.5V to ±20V), precision RON matching (≤0.01%), and robust industrial-grade leakage performance - making it optimal for high-accuracy, multi-channel data acquisition where signal integrity across varying voltage domains is critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX392CSE+?
The MAX392CSE+ supports analog signals from V− to V+ across its entire operating range. With ±15V dual supplies, it handles ±15V signals rail-to-rail. In single-supply mode (e.g., V+ = +30V, V− = 0V), it routes signals from 0V to +30V. This makes MAX392CSE+ suitable for industrial ±10V I/O standards and high-voltage sensor interfaces without external level-shifting circuitry.
Does the MAX392CSE+ require external pull-up resistors on its control inputs?
No, the MAX392CSE+ does not require external pull-up resistors. Its IN pins have TTL/CMOS-compatible thresholds referenced to VSS, with guaranteed recognition of logic-low ≤0.8V and logic-high ≥2.0V (at V+ = ±15V). Internal input hysteresis ensures noise immunity, and the device operates reliably with direct FPGA or microcontroller GPIO connections - simplifying layout and reducing BOM count for MAX392CSE+ implementations.
How does charge injection in the MAX392CSE+ affect settling time in high-resolution ADC applications?
With guaranteed <5pC charge injection, the MAX392CSE+ limits voltage glitch on a 100pF sampling capacitor to <50mV. When paired with a 10Ω series resistor (typical ADC input impedance), this results in a 5ns RC time constant - enabling full settling within 500ns for 16-bit accuracy. This performance is validated in MAX392CSE+ typical operating characteristics plots and directly supports 100kSPS+ SAR ADC throughput without additional blanking delays.
Can the MAX392CSE+ operate with mismatched dual supplies, such as +12V and −5V?
Yes, the MAX392CSE+ supports asymmetric dual supplies. Its absolute maximum ratings allow V+ up to +44V and |V−| up to 20V independently, provided the total supply span (V+ − V−) does not exceed 44V. For example, +12V and −5V (17V span) is fully within specification. This flexibility enables MAX392CSE+ integration into legacy systems with non-symmetric power rails while maintaining guaranteed RON and leakage performance.
Is thermal drift of on-resistance specified for the MAX392CSE+?
Yes, the MAX392CSE+ datasheet specifies RON drift over temperature: ±350ppm/°C typical. At +85°C, RON increases by ≤3.5% versus +25°C - well within 0.01% matching tolerance across channels. This low drift, combined with guaranteed monotonic RON vs. VCOM behavior, ensures stable gain accuracy in temperature-varying environments like factory-floor PLC modules using MAX392CSE+.
