www.ti.com SNAS547C – FEBRUARY 1995 – REVISED APRIL 2013 LM384 5W Audio Power Amplifier
Check for Samples: LM384 FEATURES DESCRIPTION The LM384 is a power audio amplifier for consumer
applications. In order to hold system cost to a
minimum, gain is internally fixed at 34 dB. A unique
input stage allows ground referenced input signals.
The output automatically self-centers to one-half the
supply voltage. 1 2 Wide Supply Voltage Range: 12V to 26V
Low Quiescent Power Drain
Voltage Gain Fixed at 50
High Peak Current Capability: 1.3A
Input Referenced to GND
High Input Impedance: 150kΩ
Low Distortion: 0.25% (PO=4W, RL=8Ω)
Quiescent Output Voltage is at One Half of the
Supply Voltage
14-Pin PDIP Package The output is short-circuit proof with internal thermal
limiting. The package outline is standard dual-in-line.
A copper lead frame is used with the center three
pins on either side comprising a heat sink. This
makes the device easy to use in standard p-c layout.
Uses include simple phonograph amplifiers,
intercoms, line drivers, teaching machine outputs, …
