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 23dB Class A preamp followed by a 40dB Class B output stage.
Both stages incorporate negative feedback to control gain, minimize distortion and stabilize operation at very low quiescent currents.

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