Analog Devices MAX997
MAX997 variants from Analog Devices
MAX997 Overview
What changes between part numbers, and what to check before you lock the BOM — Comparators.
MAX997 is a Analog Devices order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: 8-SOIC (0.154", 3.90mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C | Type: General Purpose | Output Type: CMOS, TTL | Supplier Device Package: 8-SOIC Other listed variants describe: Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 85°C | Type: General Purpose | Output Type: CMOS, TTL | Supplier Device Package: 8-uMAX/uSOP.
Across listed variants, watch these parameters: packages: 8-SOIC (0.154", 3.90mm Width), 8-TSSOP, 8-MSOP (0.118", 3.00mm Width).
Suffix examples in this family: ESA+T, EUA+T. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: MAX997ESA+T, MAX997EUA+T.
Key Features
- Footprint / package: 8-SOIC (0.154", 3.90mm Width), 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: ESA+T, EUA+T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Comparators — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained

| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|

Ordering Code Differences
How suffixes on MAX997 map to package, grade, and reel options.
MAX997 uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: ESA+T, EUA+T.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: MAX997ESA+T, MAX997EUA+T.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right MAX997 Comparators
Match the footprint first
Packages here: 8-SOIC (0.154", 3.90mm Width), 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For MAX997, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "MAX997" — include the full suffix (e.g. ESA+T, EUA+T). RFQ with reel/tube preference and required date code.
