Maxim Product Naming Conventions
Product Numbers for Second-Sourced PartsSecond-source products follow the most widely accepted numbering system for that particular part, rather than our own convention. This includes the original designators for product grade, temperature range, package type, and number of pins.
Maxim frequently supplies second-source products in packages or temperature ranges that are not supplied by other manufacturers. Whenever possible, these devices are given part numbers that follow the original numbering convention.
Product Numbers for Proprietary PartsMost Maxim parts use our own part numbering system which consists of a root part number followed by three or four suffix letters, plus optional additional designators. Example:
(A) is the Root Part Number
The root part number (also called the base part number) identifies the product type, independent of package, temperature, and other variants. Variants such as accuracy grade are usually denoted in the suffix but sometime a variant will be assigned a new root part number.
(B) is the Three- or Four-Letter Suffix
When a part has a four-letter suffix, the first letter of the suffix denotes product grade (accuracy, voltage spec, speed, etc.) For example, the first "A " in MAX631ACPA indicates 5% output accuracy. The product's full data sheet details the grades that apply to that part.
The next three characters are the three-letter suffix. The three letters denote temperature range, package type, and number of pins. The meanings are defined in the tables below.
Example: MAX696CWE
C = Operating Temperature Range C (0°C to +70°C)
W = Package Type W (SOIC 0.300")
E = Number of Pins category E (16 pins for this package)
Please note that suffix codes are not always consistent for different product types. Always refer to the data sheet for details and specifications.
