Texas Instruments LM380N
LM380N variants from Texas Instruments
LM380N Overview
What changes between part numbers, and what to check before you lock the BOM — Audio Amplifiers.
LM380N is a Texas Instruments 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: PDIP | Operating Supply Voltage: 18V | Max Supply Voltage: 22V | Min Supply Voltage: 10V | Number of Channels: 1 | Max Operating Temp: 70°C | Min Operating Temp: 0°C | Bandwidth: 100kHz Other listed variants describe: Package: DIP | Operating Supply Voltage: 18V | Max Supply Voltage: 22V | Min Supply Voltage: 10V | Number of Channels: 1 | Max Operating Temp: 70°C | Min Operating Temp: 0°C.
Across listed variants, watch these parameters: packages: PDIP, DIP.
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: LM380N, LM380N/NOPB.
Key Features
- Footprint / package: PDIP, DIPLand 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.
Target Applications
- Audio 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 LM380N 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 |
|---|---|---|---|---|---|---|---|
| LM380N | Package: PDIP | Operating Supply Voltage: 18V | Max Supply Voltage: 22V | Min Supply Voltage: 10V | Number of Channels: 1 | Max Operating Temp: 70°C | Min Operating Temp: 0°C | Bandwidth: 100kHz | PDIP | Texas Instruments | Active | Compliant | In Stock | |
| LM380N/NOPB | Package: DIP | Operating Supply Voltage: 18V | Max Supply Voltage: 22V | Min Supply Voltage: 10V | Number of Channels: 1 | Max Operating Temp: 70°C | Min Operating Temp: 0°C | DIP | Texas Instruments | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on LM380N map to package, grade, and reel options.
LM380N 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: NOPB.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: LM380N/NOPB.
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 LM380N Audio Amplifiers
Match the footprint first
Packages here: PDIP, DIP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM380N, 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 "LM380N" — include the full suffix (e.g. NOPB). RFQ with reel/tube preference and required date code.
