High Power Class B Amplifier
LC552 DATA SHEET
DESCRIPTION
The LC552 is a versatile low voltage, high gain, high power
output amplifier.
It features a preamplifier module with adjustable gain and a
unique power amplifier module that can be operated either as
a high power, high efficiency class B amplifier, with very low
quiescent current consumption, or as a medium power
"vari-bias" class A amplifier.
While designed specifically for use in body type hearing aids,
the LC552 can be used in other applications where linear audio
frequency amplification and frequency shaping is required.
FEATURES
operates over a supply range of 1.0 V to 3.0 V
selectable class B or vari-bias class A operation
feedback stabilized gain
≤ 80 dB
high power output > 140 dBSPL
independent preamplifier and output modules
minimum external parts count
