Product details
Overview
MAX393EUE from Maxim Integrated is a precision quad SPST analog switch in 16-pin TSSOP package, featuring 35Ω on-resistance (at ±5V supplies), <1pC charge injection, and ±15V analog signal range. It operates from dual ±3V to ±15V or single +3V to +15V supplies and is used in precision instrumentation multiplexing and data acquisition front-ends.
For engineers reviewing the MAX393EUE datasheet, MAX393EUE pinout, MAX393EUE application, or MAX393EUE equivalent, key selection criteria include guaranteed low on-resistance flatness (±0.5Ω over signal range), rail-to-rail analog switching capability, and specified leakage performance at temperature extremes (±125°C).
Technical Context
The MAX393EUE implements four independent single-pole single-throw (SPST) switches using complementary MOSFET topologies with matched channel design to minimize on-resistance variation across VCOM. Its control logic accepts TTL/CMOS-compatible inputs referenced to V+.
It supports both single-supply (V− = 0V) and dual-supply (V− negative) operation, with guaranteed performance over full industrial temperature range (−40°C to +85°C) and specified leakage currents (<1nA at +25°C, <10nA at +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 35Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision gain-setting or sensor interface paths |
| On-Resistance Match | ±0.5Ω max between channels - critical for matched-path applications like differential signal routing or chopper-stabilized amplifiers |
| Charge Injection | 0.6pC typical - reduces settling error and pedestal distortion in sample-and-hold and ADC input conditioning circuits |
| Analog Signal Range | ±15V - enables direct interfacing with industrial sensors, transducers, and op-amp outputs without level-shifting |
| Off-Leakage Current | 1nA max at +25°C - preserves high-impedance node integrity in battery-powered or low-power measurement systems |
| Supply Voltage Range | ±3V to ±15V dual or +3V to +15V single - provides flexibility in mixed-signal system power architecture |
| Switching Time (tON/tOFF) | 100ns/75ns typical - supports multiplexing of moderate-speed signals up to ~1MHz without significant timing skew |
Pinout & Package
MAX393EUE is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 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 corresponding IN is high |
| 2, 6, 10, 14 | COM (Common) | Analog signal path common node - must remain within ±15V of V− and ≤ V+ −1V |
| 3, 7, 11, 15 | IN (Control Input) | TTL/CMOS-compatible digital control - active-high logic turns switch ON (NO to COM) |
| 4 | V+ | Positive supply rail - must be ≥ |V−| + 2V and ≤ +15V for proper channel enhancement |
| 16 | V− | Negative supply rail - required for dual-supply operation; tied to GND for single-supply use |
| 8 | GND | Digital ground reference - separate from analog ground but must be low-impedance and co-located |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from V− to (V+ − 1V) - eliminates need for external clamping diodes in wide-dynamic-range systems |
| Guaranteed RON flatness | ±0.5Ω max over full analog range - ensures consistent channel matching in multi-channel calibration routines |
| Low charge injection | 0.6pC typical - minimizes voltage glitch on high-Z nodes during switching, critical for precision sampling |
| Specified leakage at temperature extremes | <10nA at +85°C - maintains accuracy in thermally demanding environments like motor control feedback loops |
| Single/dual supply compatibility | Operates with V− = 0V or V− = −15V - simplifies integration into legacy and new designs sharing common power domains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1434BRUZ | Lower RON (1.3Ω), higher supply current (250µA), requires external VLOGIC reference | Better for low-voltage, high-speed multiplexing; less suitable for ±15V industrial signal ranges | Select when sub-ohm RON and faster switching (<30ns) outweigh supply complexity and voltage range limitations |
| TS5A3157DCKR | Single-channel, lower voltage (5.5V max), higher RON (8Ω), no dual-supply support | Targeted at portable consumer electronics; lacks rail-to-rail analog range and temperature rating | Choose only for cost-sensitive, low-voltage, single-channel applications where ±15V operation is unnecessary |
Compared with ADG1434BRUZ and TS5A3157DCKR, the MAX393EUE uniquely delivers guaranteed ±15V analog range, industrial temperature operation, and quad-channel integration in TSSOP-making it optimal for ruggedized, wide-dynamic-range multiplexing where channel count and voltage tolerance are primary constraints.

FAQ
What is the maximum analog signal voltage range supported by the MAX393EUE?
The MAX393EUE supports an analog signal range from V− to (V+ − 1V). With ±15V supplies, this yields a full ±15V range. In single-supply mode (V− = 0V, V+ = +15V), it handles 0V to +14V signals. This rail-to-rail capability allows direct connection to industrial sensors and op-amp outputs without external level-shifting circuitry, and is explicitly guaranteed across the entire operating temperature range for the MAX393EUE.
Does the MAX393EUE require separate logic and analog supplies?
No, the MAX393EUE does not require a separate logic supply. Its IN pins accept standard TTL/CMOS logic levels referenced to V+, eliminating the need for VLOGIC. Control inputs are compatible with 3V or 5V logic families when V+ is set accordingly. This simplifies power design and reduces component count compared to switches requiring independent digital supply rails - a key feature confirmed for the MAX393EUE in its official specifications.
How does the MAX393EUE's on-resistance matching benefit precision applications?
The MAX393EUE guarantees on-resistance matching of ±0.5Ω maximum between all four channels. This tight matching ensures identical gain and offset contributions when used in differential signal paths, chopper-stabilized amplifiers, or multi-channel calibration systems. For example, in a 4-channel data logger, this spec directly limits inter-channel gain error to <0.015% - a critical parameter verified in the MAX393EUE datasheet and essential for high-accuracy measurement systems.
Can the MAX393EUE operate reliably at elevated temperatures such as +85°C?
Yes, the MAX393EUE is fully specified and guaranteed over the industrial temperature range of −40°C to +85°C. Its leakage currents, on-resistance, and switching times are all tested and bounded at +85°C. Off-leakage remains <10nA, and RON flatness holds at ±0.5Ω even at temperature extremes - making it suitable for deployment in enclosed industrial enclosures or automotive under-hood environments where thermal management is constrained, as documented for the MAX393EUE.
Is the MAX393EUE pin-compatible with other devices in the MAX39x family?
Yes, the MAX393EUE shares identical pinout and package (16-pin TSSOP) with the MAX391, MAX392, and MAX393 variants. All four devices have the same terminal arrangement for COM, NO, IN, V+, V−, and GND. However, internal configuration differs: MAX391 is dual SPST, MAX392 is dual SPDT, and MAX393 is quad SPST - so while physical layout is interchangeable, functional replacement requires verifying switch topology and channel count match for the target application of the MAX393EUE.
