Analog Devices AD8546ARMZ
AD8546ARMZ variants from Analog Devices
AD8546ARMZ Overview
What changes between part numbers, and what to check before you lock the BOM — Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers.
AD8546ARMZ 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-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Current Supply: 18µA (x2 Channels) | Output Type: Rail-to-Rail | Supplier Device Package: 8-MSOP
Across listed variants, watch these parameters: packages: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width).
Suffix examples in this family: R7, RL. 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.
Example MPNs: AD8546ARMZ-R7, AD8546ARMZ-RL.
Key Features
- Footprint / package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: R7, RL. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers — 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
Ordering Variants
Compare 2 AD8546ARMZ part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| AD8546ARMZ-R7 | Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Current Supply: 18µA (x2 Channels) | Output Type: Rail-to-Rail | Supplier Device Package: 8-MSOP | 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Analog Devices | Active | Compliant | In Stock | |
| AD8546ARMZ-RL | Package: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Current Supply: 18µA (x2 Channels) | Output Type: Rail-to-Rail | Supplier Device Package: 8-MSOP | 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) | Analog Devices | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on AD8546ARMZ map to package, grade, and reel options.
AD8546ARMZ 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: R7, RL.
Full MPN examples: AD8546ARMZ-R7, AD8546ARMZ-RL.
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 AD8546ARMZ Operational Amplifiers, Instrumentation Amplifiers and Buffer Amplifiers
Match the footprint first
Packages here: 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 AD8546ARMZ, 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 "AD8546ARMZ" — include the full suffix (e.g. R7, RL). RFQ with reel/tube preference and required date code.
