Product details
Overview
MAX393CPE 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 (max at VCOM = 0V), <±5nA off-leakage current at +25°C, and ±15V analog signal range - enabling use in high-fidelity audio switching, data acquisition front-ends, and programmable gain amplifier matrices.
For engineers reviewing the MAX393CPE datasheet, MAX393CPE pinout, MAX393CPE application, or MAX393CPE equivalent, key selection criteria include guaranteed RON flatness over signal swing, sub-5pC charge injection, -55°C to +125°C operating temperature range, and compatibility with TTL/CMOS logic levels across its four independent channels.
Technical Context
The MAX393CPE implements four independent single-pole single-throw (SPST) switches using enhancement-mode p-channel and n-channel MOSFETs in series, delivering symmetrical conduction and low THD. Its architecture ensures matched on-resistance across all channels and minimal channel-to-channel crosstalk (<−80dB at 1MHz).
It operates from dual ±3V to ±20V supplies or single +5V to +36V supplies, with logic inputs referenced to V+/V− rails. The device guarantees monotonic RON vs. VCOM behavior and maintains <100ppm/°C RON drift over temperature - critical for precision instrumentation-grade switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST - four fully isolated analog switches, each with separate control input. |
| On-Resistance (RON) | 100Ω max at VCOM = 0V, ±5V supplies - ensures minimal gain error and voltage drop in precision signal paths. |
| Off-Leakage Current | ±5nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits. |
| Charge Injection | ±5pC max - limits voltage glitch on sampled nodes, supporting 12-bit+ resolution in data acquisition. |
| Analog Signal Range | ±15V - supports rail-to-rail operation with ±5V, ±12V, or ±15V supplies without clipping. |
| Supply Voltage Range | ±3V to ±20V dual or +5V to +36V single - enables flexible system-level power architecture integration. |
| Logic Compatibility | TTL/CMOS-compatible inputs referenced to V+/V− - simplifies interface with microcontrollers and FPGAs without level-shifting. |
Pinout & Package
MAX393CPE is housed in a 16-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and standard through-hole mounting. Pin spacing is 0.1 inch (2.54 mm), compatible with industry-standard PCB footprints and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8 | NO (Normally Open) | Switch output terminals - connect to load or downstream circuit when corresponding IN is high. |
| 2, 3, 6, 7 | COM (Common) | Analog signal input terminals - shared path for all four switches' signal routing. |
| 9, 10, 11, 14 | IN (Control Input) | Active-high digital control inputs - drive respective switch ON when logic high (≥2.4V). |
| 12 | V+ | Positive supply rail - powers internal circuitry and defines upper analog signal limit. |
| 13 | V− | Negative supply rail - powers internal circuitry and defines lower analog signal limit. |
| 16 | GND | Logic ground reference - required for proper input threshold referencing and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| RON flatness | ≤10Ω variation over ±10V signal swing - maintains consistent gain and linearity in multiplexed sensor arrays. |
| Channel matching | ΔRON ≤ 5Ω between any two channels - enables precise differential signal routing and calibration. |
| Break-before-make | Guaranteed - prevents momentary shorting during channel switching, protecting sensitive sources. |
| ESD protection | ±2kV HBM - enhances robustness during board handling and system integration without external protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG444BRZ | Quad SPST, 44Ω RON (max), ±16.5V signal range, but only rated for −40°C to +85°C. | Lower RON benefits low-voltage signal integrity, but not qualified for extended industrial temperature range. | Select ADG444BRZ where ultra-low on-resistance is prioritized and ambient temperature stays within commercial range. |
| TS5A3159DCKR | Single SPDT, 0.75Ω RON, +1.65V to +5.5V single supply only - no dual-supply capability. | Optimized for low-voltage portable electronics; lacks ±15V signal handling and quad integration. | Choose TS5A3159DCKR for space-constrained, battery-powered designs requiring minimal RON at 3.3V operation. |
Compared with MAX393CPE, ADG444BRZ offers lower RON but sacrifices extended temperature support, while TS5A3159DCKR provides superior RON at low voltage yet requires redesign for dual-supply operation and channel count scaling.

FAQ
What is the maximum allowable supply voltage for MAX393CPE?
The MAX393CPE supports dual supplies from ±3V up to ±20V, or a single supply from +5V to +36V. Exceeding ±20V in dual mode or +36V in single mode risks permanent damage. Operation at ±5V is typical for precision applications, providing optimal RON flatness and leakage performance. Always observe absolute maximum ratings in the official MAX393CPE datasheet.
Does MAX393CPE support break-before-make switching?
Yes, MAX393CPE guarantees break-before-make timing between its four independent SPST switches. This prevents momentary shorting of analog signal paths during state transitions - essential for protecting voltage-sensitive sources like sensors or DAC outputs. The timing is inherent to the internal MOSFET driver design and requires no external timing components.
Can MAX393CPE be used with a single +5V supply?
Yes, MAX393CPE operates with a single +5V supply (V− tied to GND). In this configuration, the analog signal range is 0V to +5V, and logic inputs remain TTL/CMOS-compatible. However, RON increases to ~120Ω (vs. 100Ω at ±5V), and charge injection rises slightly. For rail-to-rail ±15V signal handling, dual supplies are required.
What is the typical charge injection of MAX393CPE and why does it matter?
MAX393CPE specifies ±5pC maximum charge injection. This parameter quantifies the small packet of charge injected into the COM node during switching, which can cause voltage glitches in high-impedance sample-and-hold or integrator circuits. At ±5pC, the device supports 12-bit accuracy in 10kΩ-impedance data acquisition paths without requiring additional settling time or correction circuitry.
Is MAX393CPE pin-compatible with other devices in the MAX39x family?
MAX393CPE shares the same 16-pin DIP package and pinout with MAX391CPE and MAX392CPE, differing only in channel count (quad vs. dual vs. single). All three feature identical V+, V−, GND, and logic interface arrangements. This allows direct substitution in existing layouts when scaling channel density, provided the application requires exactly four SPST switches.
