Stereo Audio Amplifier circuit using LM4752 capable of delivering 11W per channel of continuous average output power to a 4 load, or 7W per channel into 8 using a single 24V supply
Rangkaian Stereo Amplifier 11W (LM4752)The LM4752 is specifically designed for single supply operation and a low external component count. The gain and bias resistors are integrated on chip, resulting in a 11W stereo Amplifier in a compact 7 pin TO220 package. High output power levels at both 20V and 24V supplies and low external component count offer high value for compact stereo and TV applications. A simple mute function CAN be implemented with the addition of a few external components.
LM4752 Chip Features
- Drives 4Ω and 8Ω loads
- Internal gain resistors (AV = 34 dB)
- Minimum external component requirement
- Single supply operation
- Internal current limiting
- Internal thermal protection
- Compact 7-lead TO-220 package
- Low cost-per-watt
- Wide supply range 9V - 40V
