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.

FEATURES
• 23 dB class A preamp & 40 dB class B output stage
• 1.0 V DC to 1.7 V DC operating range
• 2.2 kΩ on chip microphone decoupling resistor
• 350 µA typical quiescent current
• 400 Hz to 20 kHz frequency response
