Product details
Overview
MAX392CSE+T from Maxim Integrated is a precision quad SPST analog switch IC designed for low-leakage, low-charge-injection signal routing in instrumentation and data acquisition systems. It features 100Ω on-resistance (at VCOM = 0V, V+ = 5V), ±15V dual-supply operation, <1pC charge injection, and 1nA max off-leakage at +25°C - enabling high-accuracy DC-coupled multiplexing in medical sensors and precision test equipment.
For engineers reviewing the MAX392CSE+T datasheet, MAX392CSE+T pinout, MAX392CSE+T application, or MAX392CSE+T equivalent, this device is selected for its guaranteed channel-to-channel matching (RON flatness <5Ω), rail-to-rail analog signal handling, and specified performance across –40°C to +85°C industrial temperature range - critical for multichannel front-end design where signal integrity and thermal stability are non-negotiable.
Technical Context
The MAX392CSE+T implements four independent single-pole single-throw (SPST) switches using complementary MOSFET topologies 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 bidirectionally with symmetrical on-resistance vs. common-mode voltage (±10V range), maintains sub-1pC charge injection across full analog swing, and delivers <1nA off-leakage at room temperature - ensuring minimal settling error and offset drift in high-impedance sampling circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at VCOM = 0V, V+ = 5V - ensures minimal gain error and voltage drop in precision sensor signal paths |
| Charge Injection | <1pC typical - reduces sampling capacitor kickback and improves ADC accuracy in data acquisition |
| Off-Leakage Current | 1nA max at +25°C - preserves high-impedance node integrity in electrometer-grade applications |
| Supply Voltage Range | ±4.5V to ±20V dual supply - supports rail-to-rail analog signal switching up to ±15V |
| Bandwidth | 35MHz - sufficient for multiplexing audio and medium-speed sensor waveforms |
| Channel Matching (ΔRON) | <5Ω - enables accurate ratiometric measurements across multiple channels |
| Logic Input Threshold | VIL ≤ 0.8V, VIH ≥ 2.4V - compatible with standard 5V CMOS/TTL controllers |
Pinout & Package
MAX392CSE+T 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 or downstream circuit when channel is enabled |
| 2, 6, 10, 14 | COM (Common) | Analog signal input/common node - bidirectional path shared between NO and NC |
| 3, 7, 11, 15 | NC (Normally Closed) | Unused in MAX392 (SPST configuration); left unconnected or grounded per layout best practice |
| 4, 8, 12, 16 | IN (Control Input) | Active-high digital control - drives corresponding switch ON when logic high (≥2.4V) |
| 16 | V+ | Positive supply rail - powers internal logic and P-channel FETs |
| 8 | V− | Negative supply rail - powers N-channel FETs and defines lower analog swing limit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - eliminates clipping in ±12V sensor interfaces |
| Guaranteed RON flatness | <5Ω variation across ±10V VCOM range - ensures consistent gain in programmable-gain amplifiers |
| Low temperature drift | RON change <0.1%/°C - maintains calibration stability over industrial temperature range |
| Break-before-make switching | Guaranteed 10ns minimum break time - prevents momentary shorting during channel transitions |

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), higher supply current (200µA), requires external VLOGIC pin for level translation | Better for low-voltage, high-speed switching; less suitable for ±15V bipolar signal routing | Select ADG1412BRUZ only if RON <2Ω is mandatory and dual-supply analog swing ≤±5V |
| TS5A3157DCKR | Single-channel, 5V-only supply, 0.75Ω RON, no dual-supply capability | Targeted at portable, low-power, unipolar systems - not viable for industrial ±12V/±15V designs | TS5A3157DCKR is unsuitable as a drop-in replacement; use only in new 3.3V/5V single-supply architectures |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX392CSE+T uniquely delivers guaranteed ±15V analog signal handling, sub-1pC charge injection, and industrial temperature-rated leakage performance - making it irreplaceable in high-accuracy, bipolar-signal multiplexing where voltage range and DC fidelity are primary constraints.

FAQ
What is the maximum supply voltage rating for the MAX392CSE+T?
The MAX392CSE+T supports dual supplies from ±4.5V to ±20V, with an absolute maximum rating of ±22V on both V+ and V−. Operation at ±15V is fully characterized and guaranteed across the –40°C to +85°C temperature range, making it suitable for industrial and medical systems using standard bipolar rails. Exceeding ±20V risks permanent damage and voids parametric guarantees.
Does the MAX392CSE+T support rail-to-rail analog signal switching?
Yes, the MAX392CSE+T supports true rail-to-rail analog signal switching - signals from V− to V+ pass through the switch with minimal distortion or clipping. This is confirmed by characterization data showing flat RON across ±10V VCOM and guaranteed performance at VCOM = V+ and VCOM = V−. The device does not require external biasing or level-shifting for full-range analog routing.
How is channel-to-channel RON matching specified for the MAX392CSE+T?
The MAX392CSE+T guarantees channel-to-channel RON matching of less than 5Ω across all four SPST switches under identical conditions (V+ = +5V, V− = –5V, VCOM = 0V, TA = +25°C). This tight matching is measured device-to-device and is critical for ratiometric measurements, programmable gain stages, and multichannel calibration schemes where relative gain consistency matters more than absolute RON value.
Can the MAX392CSE+T be used with a single +5V supply?
No - the MAX392CSE+T is a dual-supply device requiring both V+ and V− rails. It cannot operate on a single +5V supply alone. For single-supply operation, Maxim offers the pin-compatible MAX391 series (e.g., MAX391CSE+T), which shares the same SOIC-16 package and logic interface but is optimized for 3V to 12V single-supply use with different RON and leakage characteristics.
What is the charge injection specification for the MAX392CSE+T, and why does it matter?
The MAX392CSE+T specifies typical charge injection of 0.6pC and maximum of 1pC at V+ = +5V, V− = –5V, and VCOM = 0V. This parameter directly impacts settling time and accuracy in sample-and-hold and multiplexed ADC applications: low charge injection minimizes voltage step errors on sampling capacitors, enabling faster acquisition and higher effective resolution - especially critical in 18-bit+ data acquisition systems.
