Analog Devices Inc./Maxim Integrated MAX392ESE

Overview

MAX392ESE from Maxim Integrated is a precision quad SPST analog switch IC designed for low-distortion signal routing in instrumentation, data acquisition, and audio systems. It features 100Ω on-resistance (max), ±15V dual-supply operation, 25pC charge injection, 1nA off-leakage at +25°C, and operates over –40°C to +85°C. It is commonly used in 12-bit ADC/DAC multiplexing and test equipment front-ends.

For engineers reviewing the MAX392ESE datasheet, MAX392ESE pinout, MAX392ESE application, or MAX392ESE equivalent, key selection criteria include guaranteed R_ON flatness across V_COM, low charge injection for sampling accuracy, rail-to-rail analog signal handling, and compatibility with ±5V/±12V/±15V supplies in high-precision measurement paths.

Technical Context

The MAX392ESE implements four independent single-pole single-throw (SPST) switches using enhanced n-channel/p-channel MOSFET topologies with matched threshold voltages. Its control logic accepts TTL/CMOS-compatible inputs referenced to V+ and V–, enabling direct interface with microcontrollers without level-shifting. The device maintains symmetrical on-resistance vs. common-mode voltage behavior under both dual- and single-supply configurations.

Internal charge-pump circuitry ensures full enhancement of all MOSFETs across the full analog input range (±15V), eliminating "dead zones" near supply rails. Switch turn-on/off times are tightly specified (t_ON = 125ns, t_OFF = 100ns max) with minimal break-before-make delay, supporting high-speed multiplexed sampling without signal droop or crosstalk-induced settling errors.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage rating for the MAX392ESE?

The MAX392ESE supports dual-supply operation from ±5V up to ±15V. Absolute maximum ratings specify V+ to V– ≤ 36V, with individual rails rated to ±20V. Exceeding ±15V may degrade R_ON flatness and increase leakage; operation at ±15V is fully characterized and guaranteed per the datasheet. Always observe proper decoupling and thermal derating above +70°C ambient.

Does the MAX392ESE require external pull-up or pull-down resistors on its digital control inputs?

No, the MAX392ESE does not require external biasing on IN1–IN4. Its control inputs are fully compatible with TTL and CMOS logic families operating at 3V or 5V, with guaranteed recognition of logic high (≥2.4V) and logic low (≤0.8V) across the full temperature range. Internal input structure provides adequate noise immunity without external resistors, simplifying PCB layout and reducing BOM count.

Can the MAX392ESE be used with a single +12V supply instead of dual ± supplies?

Yes, the MAX392ESE supports single-supply operation with V+ = +12V and V– = 0V (GND). In this configuration, the analog signal range is 0V to +12V, and R_ON remains ≤100Ω with flatness maintained across the full 0V–12V span. Charge injection increases slightly (to 30pC), and off-leakage rises to 5nA max at +25°C-both remain within specification and suitable for most 12-bit applications.

How does the MAX392ESE handle signals exceeding the supply rails?

Signals applied to COM or NO pins must remain within the supply rails (V– ≤ V_ANALOG ≤ V+). The MAX392ESE has no overvoltage protection; applying signals beyond V+ or below V– will forward-bias internal ESD diodes, causing latch-up or permanent damage. For overvoltage-tolerant operation, external clamping diodes or dedicated fault-protected switches like the MAX14661 are required.

Is the MAX392ESE pin-compatible with the MAX391 or MAX393?

Yes, the MAX392ESE shares identical pinout, package, and electrical specifications with the MAX391 (dual) and MAX393 (quad) in the same SOIC-16 package. All three devices use the same footprint, control logic, and supply connections, enabling drop-in replacement across channel-count variants without PCB redesign. Functional differences are limited to number of switches (2 vs. 4) and minor parameter spreads.
