DESCRIPTION
The LC550 is a low voltage linear monolithic integrated
circuit amplifier. It is comprised of two separate amplifiers
on a single chip. The first is a 23 dB Class A preamp
followed by a 40 dB Class B output stage.
Both stages incorporate negative feedback to control
gain, minimize distortion and stabilize operation at very
low quiescent currents.
The preamp and output stage have their inputs and outputs
separately pinned out. This is an advantage as it allows
access to both stages, providing the designer with flexibility
and a full range volume control.
The combination of low quiescent current and a medium
power push-pull output makes the LC550 suitable for
medium power BTE hearing aids and for high power ITE
aids where efficiency and battery life are a premium
consideration.
