Product details
Overview
MAX393CSE+T from Maxim Integrated is a precision quad SPST analog switch IC with 100Ω on-resistance (typ), ±15V dual-supply operation, and 10pC charge injection - designed for low-distortion signal routing in instrumentation, data acquisition, and audio switching applications.
For engineers reviewing the MAX393CSE+T datasheet, MAX393CSE+T pinout, MAX393CSE+T application, or MAX393CSE+T equivalent, key selection criteria include guaranteed RON flatness over signal range, sub-10nA leakage at +125°C, rail-to-rail analog signal handling, and SOIC-16 package compatibility with legacy PCB layouts.
Technical Context
The MAX393CSE+T implements four independent single-pole/single-throw (SPST) switches using enhanced n-channel/p-channel MOSFET topologies to achieve symmetrical conduction and minimal signal-dependent on-resistance variation. Its control logic accepts TTL/CMOS-compatible inputs referenced to V+ or ground.
It operates across ±4.5V to ±20V dual supplies or +10V to +44V single supply, with guaranteed performance over –40°C to +85°C ambient. Charge injection and off-leakage are characterized and specified per channel under worst-case voltage and temperature conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RON (max) | 120Ω - ensures ≤0.1% gain error in 12-bit DAC output buffering at 10kΩ load |
| RON flatness (ΔRON) | 15Ω - maintains consistent channel matching in multiplexed sensor front-ends |
| Charge injection | 10pC (max) - limits settling error to <1LSB in 16-bit SAR ADC sample-and-hold paths |
| Off-leakage (IOFF) | 10nA at +85°C - prevents >1mV offset drift in high-impedance pH probe interfaces |
| Supply range | ±4.5V to ±20V dual or +10V to +44V single - supports industrial ±15V and automotive 24V systems |
| Bandwidth | 30MHz - enables clean switching of audio signals up to 20kHz with <0.01% THD+N |
| Logic compatibility | TTL/CMOS - allows direct interfacing with microcontrollers and FPGAs without level-shifting |
Pinout & Package
MAX393CSE+T is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, JEDEC MS-012AC compliant footprint, and exposed pad omitted - suitable for reflow soldering and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NO (Normally Open) | Switch output terminal - connects to load only when corresponding IN is high |
| 2, 6, 10, 14 | COM | Common analog path - bidirectional signal interface shared with NO/NC |
| 3, 7, 11, 15 | IN | Digital control input - active-high TTL/CMOS logic drives channel ON/OFF state |
| 4, 16 | V− / V+ | Negative/positive supply rails - must be decoupled locally with ≥0.1µF ceramic capacitors |
| 8, 12 | GND | Analog/digital ground reference - requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full-swing signals from V− to V+, enabling ±10V sensor conditioning without clipping |
| Guaranteed RON matching | ≤5Ω max mismatch between channels - critical for simultaneous sampling in multi-channel DAQ systems |
| Low temperature coefficient | 300ppm/°C RON drift - maintains calibration stability across industrial temperature ranges |
| Break-before-make timing | Guaranteed 10ns minimum break time - prevents momentary shorting during channel switching |
| ESD protection | ±2kV HBM - eliminates need for external TVS diodes in board-level ESD testing environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG413BRZ | Higher RON (150Ω typ), lower supply voltage (±15V max), no guaranteed RON flatness spec | Suitable for general-purpose switching but not for precision 16-bit+ data acquisition | Select when cost sensitivity outweighs RON matching requirements |
| TS5A3157DCKR | Single-channel, lower voltage (5.5V max), higher leakage (>100nA at +85°C), SC70-6 package | Targeted at portable battery-powered signal routing, not industrial ±15V systems | Choose only for space-constrained, low-voltage consumer designs |
Compared with ADG413BRZ and TS5A3157DCKR, the MAX393CSE+T delivers superior RON flatness and lower leakage for precision measurement, while supporting wider supply rails essential for industrial analog signal chains - making it the optimal choice where channel matching and long-term calibration stability are critical.

FAQ
What is the maximum supply voltage rating for MAX393CSE+T?
The MAX393CSE+T supports dual supplies from ±4.5V to ±20V, meaning its absolute maximum V+ is +20V and V− is –20V. Exceeding these ratings risks permanent damage. For single-supply operation, it accepts +10V to +44V between V+ and GND, with V− tied to GND. Always observe the 40V total supply range limit (V+ − V− ≤ 40V) regardless of configuration.
Does MAX393CSE+T require external pull-up resistors on its IN pins?
No, MAX393CSE+T does not require external pull-up resistors on its IN pins. Its digital inputs are fully TTL/CMOS compatible with guaranteed thresholds: logic high recognized at ≥2.4V (min) and logic low at ≤0.8V (max) when V+ = +5V. The internal input structure provides sufficient noise immunity and drive capability for direct connection to microcontroller GPIOs or FPGA outputs without additional components.
Can MAX393CSE+T be used with single-ended 0V to +5V analog signals?
Yes, MAX393CSE+T can route 0V to +5V analog signals in single-supply mode. Configure V+ = +5V, V− = 0V (GND), and ensure all COM/NO terminals remain within the 0V to +5V range. Signal integrity is preserved due to rail-to-rail operation and low RON flatness. However, note that charge injection and leakage specs are optimized for dual-supply use; verify performance meets your 12-bit+ accuracy requirements via bench testing.
What is the thermal resistance (θJA) of the MAX393CSE+T in SOIC-16 package?
The MAX393CSE+T in 16-pin SOIC package has a junction-to-ambient thermal resistance (θJA) of 110°C/W under standard JEDEC JESD51-7 conditions (single-layer 1-in² copper pad). With typical operating power dissipation below 10mW per channel, self-heating remains negligible (<1°C rise) in most PCB layouts. For high-density designs, adding thermal vias under the exposed pad area (if present) further reduces θJA, though the CSE+T variant lacks an exposed thermal pad.
Is MAX393CSE+T pin-compatible with earlier MAX393 variants like MAX393CPD?
Yes, MAX393CSE+T is pin-compatible with MAX393CPD and MAX393CPE+ across all 16 pins. Both share identical SOIC-16 footprints, pin functions, and electrical behavior. The "CSE+T" suffix denotes tape-and-reel packaging and extended temperature grade (–40°C to +85°C), whereas CPD is plastic DIP and CPE+ is SOIC with different packaging. No PCB layout changes are required when upgrading from CPD/CPE+ to CSE+T.
