LC550 DATA SHEET

FEATURES

DESCRIPTION

• 23 dB class A preamp & 40 dB class B output stage

• 1.0 V DC to 1.7 V DC operating range

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.

• 2.2 kΩ on chip microphone decoupling resistor

• 350 µA typical quiescent current

Both stages incorporate negative feedback to control

gain, minimize distortion and stabilize operation at very

low quiescent currents.

• 400 Hz to 20 kHz frequency response

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.

STANDARD PACKAGING

• 10 pin MICROpac

• 10 pin MINIpac

• 10 pin SLT

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.

• 10 pin PLID

• Chip (57 x 47 mils)
