Ordering number:ENN528D
Monolithic Linear IC
LA4140
0.5W AF Power Amplifier
Features
• Output power 0.5W typ (VCC=6V, RL=8Ω, THD=10%).
• Low quiescent current.
• Wide operating voltage range : V
=3.5 to 12V.
CC
• 9-pin SIP permitting sets to be small-sized and eliminating the need to use a heat sink.

Notice for Using IC
(1) Maximum Ratings
Enough margin converting supply voltage drifting should be prepared and disigning over maximum ratings
should be absolutely avoided because operation near these ratings causes going across the ratings and leading to
destruction.
(2) Terminating Pins
Turning the circuit on leaving pin to pin of IC shorted causes destruction of failure. Turn on ascertaining that
solder has never shorted pins when setting IC to printed board.
(3) Location
When used in a radio receiver, IC is designed to locate apart from a bar antenua enough.
(4) Printed Pattern Designing
As designing a printed pattern, lines of power supply, output adn ground are to be widely short and pattern and
peripheral parts are considerably set not to feedback from output to input.
Also, a capacitor C8 at power line, C5 and C9 of anti-oscillator are to be arranged near to pins of IC.
