Frequently Asked Questions
What is the output power of the LM3875TF/NOPB?
The LM3875TF/NOPB delivers 56W of continuous average output power into an 8Ω load at 60V supply with less than 0.1% THD+N. It can also deliver approximately 60W into a 4Ω load, making it suitable for high-power audio applications.
What supply voltage does the LM3875TF/NOPB require?
The LM3875TF/NOPB operates from a single supply voltage ranging from 20V to 84V, or a split supply of ±10V to ±42V. This wide range allows flexible power supply design for both home audio and professional audio equipment.
What package is the LM3875TF/NOPB available in?
The LM3875TF/NOPB is housed in an 11-pin TO-220 package with an exposed metal tab for heat sinking. The 'TF' suffix denotes the TO-220 full-pack package, which requires an external heatsink for proper thermal management during high-power operation.
What protection features does the LM3875 include?
The LM3875TF/NOPB integrates multiple protection features including self-peak instantaneous temperature (SPiKe) protection, output current limiting, and thermal shutdown. These protect the device from damage caused by short circuits, overloads, and excessive junction temperatures.
Can the LM3875TF/NOPB be used in a bridged amplifier configuration?
Yes, two LM3875 devices can be configured in a bridge-tied load (BTL) configuration to double the output power to approximately 120W into an 8Ω load. This makes it popular for mono subwoofer amplifiers and high-power stereo systems in DIY audio projects.
