High Gain Class A Amplifier
with Peak Clipping
DESCRIPTION
The LS505 is a low voltage, monolithic integrated circuit
amplifier comprised of an operational amplifier driving a
single transistor Class A output stage with open collector.
Also included are a pair of complementary Schottky diodes
which provide the capability for symmetrical peak clipping in
a feedback configuration.
An internal negative feedback loop ensures a stable operating
point for the output stage over the designed operating voltage.
This also permits trimming of the output current with the use
of a single external resistor.
The input stage and microphone are biased by an internal
2.2 k? decoupling resistor to increase battery line signal
rejection.
