TEXAS INSTRUMENTS LM380N Audio Power Amplifier 2.5W DIP 8 Pin

The TEXAS INSTRUMENTS LM380N-8/NOPB is a 2.5W audio power amplifier designed for consumer applications. With a class AB output and a wide supply voltage range of 10V to 22V, this through-hole DIP package amplifier is ideal for a variety of audio signal processing tasks. The gain is internally fixed at 34dB, minimizing external component count and holding system cost to a minimum. An unique input stage allows ground referenced input signals, making it easy to interface with various audio sources.

The output automatically self-centers to one-half the supply voltage, ensuring optimal dynamic range. The device is short circuit proof with internal thermal limiting for reliable protection. The standard dual-in-line package outline, combined with a copper lead-frame and center pins acting as a heat sink, makes this amplifier easy to use in standard PCB layouts.

Key Features:

• Voltage gain fixed at 50 (34dB)
• High peak current capability
• Low quiescent power drain
• Input referenced to GND
• High input impedance
• Low distortion
• Quiescent output voltage at one-half supply voltage
• Green product (no Sb/Br)

Applications include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small servo drivers, and power converters. Note: The device has limited built-in ESD protection; leads should be shorted or placed in conductive foam during storage or handling.
