Product details
Overview
MAX393EUE+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 or +5V single-supply systems. It features 100Ω on-resistance (typ), <1pC charge injection, ±20nA max off-leakage at +85°C, and operates over –40°C to +85°C. It is used in data acquisition front-ends, programmable gain amplifiers, and automatic test equipment.
For engineers reviewing the MAX393EUE+T datasheet, MAX393EUE+T pinout, MAX393EUE+T application, or MAX393EUE+T equivalent, key selection criteria include guaranteed RON flatness across VCOM, sub-pC charge injection for minimal settling error, rail-to-rail analog signal handling, and compatibility with TTL/CMOS logic levels.
Technical Context
The MAX393EUE+T implements four independent single-pole single-throw (SPST) switches using enhanced n-channel DMOS technology. Each switch exhibits symmetrical conduction for bidirectional analog signals and maintains stable RON (<120Ω max) over its full ±4.5V analog input range when powered from ±5V supplies.
Its control inputs accept standard TTL/CMOS logic thresholds and are fully compatible with 3V or 5V digital controllers. The device guarantees no-break-before-make operation and supports both single-supply (+5V) and split-supply (±5V) configurations without external level-shifting circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG413BRUZ | Higher RON (150Ω max), higher charge injection (2.5pC), wider supply range (±15V). | Better suited for high-voltage industrial I/O, less optimal for low-error precision gain setting. | Select ADG413BRUZ only if ±15V operation is required; otherwise MAX393EUE+T offers superior precision at ±5V. |
| TS5A23157DCUR | Lower RON (0.9Ω typ), but rated only for +5V single supply and 3.3V logic; no ±5V dual-supply support. | Ideal for low-voltage portable devices, incompatible with legacy ±5V signal chains. | Choose TS5A23157DCUR for battery-powered designs with 3.3V control; MAX393EUE+T remains preferred for industrial ±5V systems. |
Compared with ADG413BRUZ and TS5A23157DCUR, the MAX393EUE+T uniquely balances ultra-low charge injection, guaranteed dual-supply operation, and industrial temperature qualification-making it the optimal choice for precision, ±5V-compatible analog multiplexing where signal fidelity and temperature stability are critical.

FAQ
What is the maximum allowable analog signal range for MAX393EUE+T when operated from ±5V supplies?
The MAX393EUE+T supports a full analog signal range of ±4.5V when powered from ±5V supplies. This rail-to-rail capability ensures that signals from –4.5V to +4.5V pass through the switch with minimal distortion or clipping, making it ideal for precision instrumentation where signal headroom and dynamic range are critical. The specification is guaranteed across the full –40°C to +85°C operating temperature range.
Does MAX393EUE+T require external pull-up or pull-down resistors on its digital control inputs?
No, MAX393EUE+T does not require external pull-up or pull-down resistors on its IN pins. Its control inputs are TTL/CMOS compatible with guaranteed thresholds: logic high is recognized at ≥2.4V (for +5V V+), and logic low at ≤0.8V. Internal input structure provides sufficient noise immunity and defined states without external biasing, simplifying PCB layout and reducing BOM count in systems using microcontrollers or FPGAs with strong drive capability.
Can MAX393EUE+T be used in a single-supply +5V configuration while handling bipolar analog signals?
Yes, MAX393EUE+T can operate from a single +5V supply (V+ = +5V, V− = 0V) and still pass bipolar analog signals-provided the signal remains within the 0V to +5V range. However, true bipolar (±) signal handling requires the dual-supply configuration (V+ = +5V, V− = –5V). In single-supply mode, the device supports rail-to-rail analog operation from 0V to +5V, enabling use in DC-coupled sensor interfaces and microcontroller-based signal conditioning where ground-referenced signals dominate.
How does the charge injection specification of MAX393EUE+T impact its suitability for sample-and-hold circuits?
The MAX393EUE+T's guaranteed charge injection of <1pC directly minimizes hold-mode voltage error and settling time in sample-and-hold (S/H) circuits. At typical hold capacitor values (e.g., 100pF), this results in a worst-case voltage glitch of <10mV-well below 12-bit LSB thresholds. This performance, combined with low on-resistance and leakage, makes the MAX393EUE+T a validated choice for medium-speed S/H stages in precision data converters and waveform digitizers.
Is MAX393EUE+T pin-compatible with other devices in the MAX391/MAX392/MAX393 family?
Yes, MAX393EUE+T is pin-compatible with MAX391EUE+T (quad SPST) and MAX392EUE+T (dual SPDT) in the same 16-pin TSSOP package. All three share identical pin assignments for power, ground, control, and analog terminals-enabling flexible design reuse and drop-in substitution where channel count or topology permits. This compatibility simplifies schematic updates and reduces layout iterations across related precision analog switch implementations.
