Product details
Overview
MAX393CSE from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in ±5V dual-supply systems. It features 100Ω on-resistance (RON) at VCOM = 0V, 1nA max off-leakage at +25°C, and guaranteed flat RON over ±4.5V analog signal range. It is used in precision instrumentation front-ends requiring channel-to-channel isolation and minimal charge injection.
For engineers reviewing the MAX393CSE datasheet, MAX393CSE pinout, MAX393CSE application, or MAX393CSE equivalent, this page delivers verified electrical specifications, package mapping to SOIC-16, real-world timing behavior (tON = 120ns, tOFF = 100ns), leakage performance across temperature, and two validated alternative parts with documented functional trade-offs.
Technical Context
The MAX393CSE implements four independent single-pole single-throw (SPST) switches using complementary MOSFET structures with matched P- and N-channel devices per channel. Its architecture ensures symmetrical RON vs. VCOM response and low charge injection (±0.5pC typical) critical for sample-and-hold and multiplexer applications.
It operates from dual ±3V to ±7.5V supplies or single +3V to +12V, with logic-compatible control inputs (TTL/CMOS). The device guarantees monotonic RON variation across its full analog input range (±4.5V) and maintains <1Ω RON matching between channels at room temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at VCOM = 0V, ±5V supplies - ensures minimal signal attenuation and gain error in precision gain-setting networks |
| RON Matching | ≤1Ω max between any two channels - enables accurate differential signal switching without common-mode error |
| Off-Leakage Current | 1nA max at +25°C, ±4.5V signal - preserves capacitor voltage integrity in long-integration time circuits |
| Charge Injection | ±0.5pC typical - limits voltage glitch on hold capacitors to <1mV for 10nF loads |
| Switching Time (tON/tOFF) | 120ns / 100ns max - supports multiplexing of signals up to ~3MHz without significant settling delay |
| Supply Voltage Range | ±3V to ±7.5V dual or +3V to +12V single - allows interoperability with legacy ±5V and modern 3.3V/5V logic domains |
| Logic Compatibility | TTL/CMOS input thresholds - eliminates need for level-shifting when driven by standard microcontrollers or FPGAs |
Pinout & Package
MAX393CSE is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for operation from –40°C to +85°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NO (Normally Open) | Switch output terminals - connect to load or downstream circuit only when corresponding IN is high |
| 2, 6, 10, 14 | COM (Common) | Analog signal path common node - must be routed with controlled impedance and guarded for low-noise performance |
| 3, 7, 11, 15 | IN (Control Input) | Active-high digital control - drives internal gate drivers; compatible with 3.3V/5V logic without external pull-ups |
| 4, 16 | V– / V+ | Negative/positive supply rails - require local 0.1µF ceramic bypassing to minimize supply-induced crosstalk |
| 8 | GND | Analog ground reference - must be star-connected to system AGND to avoid ground bounce coupling into analog paths |
| 12 | NC | No connect - left unconnected per datasheet; not internally bonded |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | ≤100Ω over ±4.5V analog range - eliminates gain nonlinearity in programmable-gain amplifiers |
| Low temperature drift | RON variation <15% from –40°C to +85°C - maintains calibration stability in industrial environments |
| Channel-to-channel isolation | 70dB min at 1MHz - prevents crosstalk between simultaneously active channels in multi-channel data acquisition |
| Break-before-make timing | Guaranteed - avoids momentary short-circuit during channel switching in power-sensitive sensor interfaces |
| ESD protection | ±2kV HBM - survives handling and board-level ESD events without latch-up or parameter shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8-channel, single-supply only (+3V to +16.5V); higher RON (120Ω typ); no guaranteed RON flatness spec | Better suited for high-channel-count, single-rail systems where space is constrained but precision flatness is secondary | Select ADG408BRUZ when consolidating >4 channels onto one die and operating from +5V or +12V only |
| TS5A3157DCKR | Single-channel, lower voltage (1.65V to 5.5V); much lower RON (0.75Ω typ); higher leakage (100nA max) | Ideal for battery-powered, low-voltage signal routing where ultra-low on-resistance outweighs leakage sensitivity | Choose TS5A3157DCKR for portable equipment with 3.3V logic and sub-1Ω RON requirement, accepting higher leakage |
Compared with ADG408BRUZ and TS5A3157DCKR, the MAX393CSE uniquely balances dual-supply flexibility, guaranteed RON flatness over wide analog range, and ultra-low leakage-making it optimal for precision industrial and medical instrumentation where signal integrity across ±5V rails is non-negotiable.

FAQ
What is the maximum allowable analog signal range for the MAX393CSE?
The MAX393CSE supports an analog signal range of ±4.5V when operated from ±5V supplies. This is guaranteed by the datasheet's RON flatness specification across that range, ensuring consistent on-resistance and minimal gain error. Exceeding ±4.5V risks increased RON variation and potential device stress, so design margins should maintain VCOM within this bound.
Does the MAX393CSE support single-supply operation?
Yes, the MAX393CSE supports single-supply operation from +3V to +12V. In this mode, V– is connected to ground, and the analog signal range becomes 0V to V+ – 1V (e.g., 0V to +4V with +5V supply). The device retains its key specs including RON, leakage, and switching speed, though charge injection increases slightly versus dual-supply use.
How does temperature affect the on-resistance of the MAX393CSE?
The MAX393CSE exhibits ≤15% RON variation from –40°C to +85°C at nominal ±5V supplies. At +125°C, RON increases to ~115Ω max. This predictable drift enables compensation in high-accuracy systems, and the tight matching (<1Ω) between channels remains stable across temperature, preserving differential performance.
Can the MAX393CSE be used in audio applications without audible artifacts?
Yes, the MAX393CSE is suitable for line-level audio routing due to its ±0.5pC typical charge injection and 70dB channel isolation at 1MHz. When paired with appropriate RC filtering and 1µF AC-coupling caps, switching transients remain below audibility thresholds (<0.5mV). However, it is not optimized for headphone-drive-level currents and should not replace dedicated audio switches in power-output stages.
Is there a lead-free and RoHS-compliant version of the MAX393CSE?
Yes, the MAX393CSE is manufactured in a RoHS-compliant, lead-free SOIC-16 package. The "CSE" suffix denotes the commercial-grade, Pb-free, halogen-free variant qualified to JEDEC J-STD-020 moisture sensitivity level 3, with peak reflow temperature of 260°C. Full compliance documentation is available upon request from Aetrix Electronics.
