LM380N LM380N

An audio amp in a 14-pin
DIL package that requires
very few external
components to make a
complete 2.5W power
amplifier. In most cases
however it is advisable
to add a Min Res 2.7Omega
and Polyester 0.1microF
in series from pin 8 to
ground and an Axial
4.7microF from pin 1 to
ground.High-Output-Crystal-Cartridge
Power AmpA 2.5W rms power
amp the 380 is shown in
the circuit driven by a
high output crystal
pickup. The IC requires
only 4 other components
without tone control only
two other components
simply omit C1 and RV1.

LM386N-1 LM386N-1

A power-amp designed for
use in low voltage
especially
battery-operated
applications such as
AM-FM radios portable
tape cassettes intercoms
power invertors etc. For
minimum parts count C1
and C2 can be omitted.
With pins 1 and 8 open
circuit the gain is
internally set to 20dB.
With a 10microF capacitor
between pins 1 and 8 the
gain is increased to
200dB and the gain can be
set to anything between
these limits by placing a
resistor in series with
this capacitor. For
example a 1k2 resistor
here sets the gain to
50dB. The capacitor on
pin 7 sets the power
supply rejection ratio
from 6dB with no
connection to 50dB at
1kHz with 10microF. The
inputs are referenced to
ground while the output
is automatically biased
to half the supply
voltage.

TDA7052 TDA7052

A power-amp designed for
use in low voltage
battery operated
equipment where a high
output power is still
required. By using the
Bridge Tied Load
principle in the amp an
output power of 1.2W into
8Omega is achieved from a
6V supply. The gain of
the amplifier is fixed
internally at 40dB and
almost no external
components are required.
The amp is short-circuit
proof requires no
external heatsink and
there are no switch-on or
switch-off clicks.

TDA2050V TDA2050V

A high quality audio-amp
in a 5-pin TO220 package
that does not require
insulating washers
between the metal tab and
heatsink in single rail
supply applications. The
amp will operate with
single or split supplies.
The amp can provide 32W
rms into a 4Omega load
and 25W rms into 8Omega.
The device features low
harmonic and crossover
distortion and a low
external component count.
The device includes short
circuit protection and
thermal shutdown.
