Product details
Overview
MAX393ESE+T from Maxim Integrated is a precision quad SPST analog switch IC designed for low-leakage, low-charge-injection signal routing in ±5V dual-supply systems. It features 100Ω on-resistance (typ), <1pC charge injection, ±10nA max off-leakage at +25°C, and operates over –40°C to +85°C. It is used in data acquisition front-ends, automatic test equipment, and precision instrumentation where signal integrity and channel-to-channel crosstalk isolation are critical.
For engineers reviewing the MAX393ESE+T datasheet, MAX393ESE+T pinout, MAX393ESE+T application, or MAX393ESE+T equivalent, key selection criteria include guaranteed RON flatness across VCOM, sub-pC charge injection, rail-to-rail analog signal handling, and compatibility with ±5V supplies without external level-shifting.
Technical Context
The MAX393ESE+T implements four independent single-pole single-throw (SPST) switches using complementary MOSFET pairs per channel, enabling true bidirectional analog signal switching. Its architecture ensures matched on-resistance and minimal distortion across the full ±4.5V analog input range when powered by ±5V supplies.
It employs a logic-compatible control interface (TTL/CMOS) referenced to ground, with guaranteed 0.8V/2.0V input thresholds. Switching is fully specified over temperature (–40°C to +85°C), and leakage performance remains stable across voltage and temperature extremes-critical for high-impedance sensor multiplexing and sample-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω typical at VCOM = 0V, ±5V supplies - ensures minimal signal attenuation and gain error in precision gain-setting networks. |
| Charge Injection | <1pC typical - prevents voltage glitches and settling errors in sample-and-hold and ADC driver stages. |
| Off-Leakage Current | ±10nA max at +25°C - preserves accuracy in high-Z sensor interfaces and battery-powered measurement nodes. |
| Supply Voltage Range | ±4.5V to ±20V dual supply - supports wide dynamic range signal routing without clipping in industrial and test systems. |
| Bandwidth | 35MHz - enables switching of fast analog waveforms up to ~5.5MHz fundamental without significant amplitude loss. |
| Logic Compatibility | TTL/CMOS inputs with VIL ≤ 0.8V, VIH ≥ 2.0V - interoperates directly with microcontrollers and FPGAs without level shifters. |
| Channel-to-Channel Crosstalk | –80dB at 1MHz - maintains signal purity in multi-channel multiplexed systems such as oscilloscope front-ends. |
Pinout & Package
MAX393ESE+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 terminal - connects to load only when corresponding IN is high; isolated otherwise. |
| 2, 6, 10, 14 | COM (Common) | Analog signal path common node - bidirectional, supports rail-to-rail ±4.5V signals. |
| 3, 7, 11, 15 | IN (Control Input) | Active-high digital control - TTL/CMOS compatible; drives internal gate drivers. |
| 4 | V+ | Positive analog supply - must be ≥ |V−| and ≤ +20V; powers all four channels. |
| 12 | V− | Negative analog supply - must be ≤ –|V+| and ≥ –20V; defines lower analog rail. |
| 8 | GND | Digital ground reference - separate from analog return; decoupling required near pins 4 and 12. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | RON variation <10Ω across ±4.5V VCOM range - eliminates gain nonlinearity in programmable-gain amplifiers. |
| Low charge injection | <1pC typical - reduces hold-step error to <0.01LSB in 16-bit SAR ADC sample-and-hold circuits. |
| Matched on-resistance | ΔRON <5Ω between channels - enables precise ratio-metric measurements in multi-sensor systems. |
| Specified leakage over temp | ±25nA max at +85°C - ensures long-term stability in unattended environmental monitoring nodes. |
| Break-before-make switching | Guaranteed 10ns minimum break time - prevents momentary shorting in redundant power-path or signal-path selectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher RON (1.8Ω typ), wider supply (±15V), but higher charge injection (3.5pC). | Better for high-voltage industrial I/O; less suitable for sub-16-bit precision sampling. | Select when ±15V operation is mandatory and charge injection tolerance >3pC is acceptable. |
| TS5A3157DCKR | Single-supply only (1.65V–5.5V), lower RON (0.75Ω), but no dual-supply support or guaranteed leakage spec. | Optimized for battery-powered portable devices; not viable for ±5V bipolar signal routing. | Choose for cost-sensitive, low-voltage consumer electronics where rail-to-rail bipolar operation is unnecessary. |
Compared with ADG1414BRUZ and TS5A3157DCKR, the MAX393ESE+T uniquely delivers guaranteed sub-pC charge injection and ±10nA off-leakage under ±5V dual-supply conditions-making it the only option among the three qualified for 16-bit+ precision multiplexing in medical and metrology equipment.

FAQ
What is the maximum allowable supply voltage for MAX393ESE+T?
The MAX393ESE+T supports dual-supply operation from ±4.5V up to ±20V. For standard use with ±5V rails, the absolute maximum ratings are V+ ≤ +20V and V− ≥ –20V. Exceeding these limits risks permanent damage. The device is fully characterized at ±5V, where RON, leakage, and charge injection meet published specifications.
Does MAX393ESE+T support single-supply operation?
No, MAX393ESE+T is designed exclusively for dual-supply operation (e.g., ±5V, ±12V). It lacks internal level-shifting circuitry for single-supply use. Attempting to operate it with V− tied to GND will result in undefined behavior and potential latch-up. For single-supply alternatives, consider the MAX391 series or ADG12xx family.
What is the guaranteed charge injection specification for MAX393ESE+T?
The MAX393ESE+T guarantees charge injection of <1pC typical at VCOM = 0V, ±5V supplies, TA = +25°C. Over temperature (–40°C to +85°C) and across the full ±4.5V analog input range, charge injection remains ≤2.5pC - a critical parameter validated in production test for precision sample-and-hold and ADC driver applications.
How does MAX393ESE+T handle logic-level compatibility?
MAX393ESE+T accepts TTL- and CMOS-compatible logic inputs referenced to GND. Its control pins (IN1–IN4) guarantee VIL ≤ 0.8V (max) and VIH ≥ 2.0V (min) across temperature, allowing direct interfacing with 3.3V or 5V microcontrollers without external level translation. No pull-up resistors are required for proper switching.
Is thermal shutdown or overcurrent protection built into MAX393ESE+T?
No, MAX393ESE+T does not include thermal shutdown or overcurrent protection circuitry. It relies on external design practices - including appropriate PCB copper area, current-limiting resistors in series with COM/NO paths, and supply decoupling - to maintain junction temperature within the –40°C to +125°C safe operating range. Continuous operation above +85°C ambient requires derating per the datasheet thermal resistance curve.
