Analog Devices Inc./Maxim Integrated MAX317ESA+

Overview

MAX317ESA+ from Maxim Integrated is a precision CMOS single-pole single-throw (SPST) analog switch with normally closed (NC) configuration, 44V breakdown voltage, <35Ω maximum on-resistance, and ±2000V ESD rating. It operates from bipolar supplies (±4.5V to ±20V) or single supply (+10V to +30V), enabling rail-to-rail analog signal handling in guidance systems and test equipment.

For engineers reviewing the MAX317ESA+ datasheet, MAX317ESA+ pinout, MAX317ESA+ application, or MAX317ESA+ equivalent, key selection criteria include guaranteed on-resistance matching (<2Ω), low charge injection (≤10pC), leakage <6nA at +85°C, and SO-8 package compatibility with industrial temperature range (-40°C to +85°C).

Technical Context

The MAX317ESA+ implements a silicon-gate CMOS architecture optimized for low distortion and high channel isolation. Its NC topology routes the COM terminal to NC when logic input is low, with break-before-make behavior absent due to SPST structure.

It supports dual-supply operation with independent V+ and V− rails, allowing analog signals to swing fully between them, while VL provides TTL/CMOS-compatible logic-level control referenced to GND. Charge injection is minimized via matched transistor design and guaranteed ≤10pC across the full analog range.

Key Specifications

Pinout & Package

MAX317ESA+ is housed in an 8-pin SO (Small Outline) package, 150-mil width, with standard JEDEC MO-153 footprint and gull-wing leads. Pin 1 marked with dot; device orientation follows standard SOIC top-view convention.

FAQ

What is the operating temperature range for MAX317ESA+?

The MAX317ESA+ is specified for operation from -40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table and Electrical Characteristics sections of the datasheet, where parameters are tested across TMIN to TMAX. The "ESA" suffix explicitly denotes the -40°C to +85°C grade, distinct from the "CSA" (0°C to +70°C) and "MJA" (-55°C to +125°C) variants. MAX317ESA+ maintains guaranteed on-resistance match and leakage specs across this full range.

Does MAX317ESA+ support single-supply operation?

Yes, MAX317ESA+ supports single-supply operation from +10V to +30V. Per the Features section and Electrical Characteristics tables, it functions with V− tied to GND (0V), V+ as the positive rail, and VL set to +5V for TTL compatibility or to V+ for CMOS logic levels. The datasheet confirms analog signal range of 0V to V+ under these conditions, and specifies RON, leakage, and switching times for +12V single-supply configurations.

What is the logic polarity of MAX317ESA+?

MAX317ESA+ has active-low logic control: when the IN pin is low (≤0.8V), the NC path is closed (COM connected to NC); when IN is high (≥2.4V), the switch opens. This is explicitly shown in the functional diagram ("SWITCHES SHOWN FOR LOGIC '0' INPUT") and confirmed by the Truth Table for MAX317. The logic input is TTL/CMOS compatible, and VL must be supplied at +5V for standard TTL thresholds.

Can MAX317ESA+ handle ±15V analog signals?

Yes, MAX317ESA+ is rated for ±15V analog signals when operated with bipolar supplies (e.g., V+ = +15V, V− = −15V). The Absolute Maximum Ratings specify V+ to V− ≤ +44V, and the Electrical Characteristics table lists analog-signal range as ±15V under dual-supply conditions. Typical Operating Characteristics graphs (MAX317-01, MAX317-02) further validate stable RON and leakage performance across ±15V signal swings.

Is MAX317ESA+ pin-compatible with other MAX317 variants?

Yes, MAX317ESA+ is pin-compatible with all MAX317 variants (e.g., MAX317CPA, MAX317EPA, MAX317CJA) in the same package type. The Pin Description table and Pin Configurations diagrams confirm identical pin numbering and function mapping across all MAX317 versions. The "ESA" suffix indicates only the temperature grade and package (SO-8); electrical and mechanical pinout remains identical to other MAX317 SO-8 variants like MAX317CSA.
