LC551 DATA SHEET
FEATURES adjustable gain capable driving impedance receiver (110 parts count, small capacitors resistor gain trim used volume control reduced noise minimal start transient
DESCRIPTION LC551 voltage, class amplifier which operates over battery voltage range
frequency bandwidth STANDARD PACKAGING PLID
Chip mils)
O/P2
LC551 consists three gain blocks. first block inverting amplifier with gain external resistors. This gain trim feature used volume control hearing applications. second block inverting unity gain amplifier which serves phase splitter. outputs from first second blocks drive differential inputs third block. third block fixed gain when driving receiver.
This amplifier internal compensation eliminating need capacitor across receiver. ground pins available "star grounding reduce second harmonic distortion produced ground line resistance.
