High Gain Class A Amplifier
LC505/LD505 DATA SHEET
FEATURES • 71 dB of gain with 1.3 V supply • 0.2 to 2.0 mA of transducer current adjustment • 43 dB of volume control range
DESCRIPTION The LC/LD505 are low voltage, linear monolithic integrated amplifiers with a typical electrical gain of 71 dB. The circuits are comprised of a compensated, unconditionally stable, operational amplifier and a low distortion Class A single transistor output stage with negative feedback for stability over a wide temperature range. Current trimming in the output stage for inductive or resistive loads can be accomplished by connecting an emitter resistor from RE to ground. The LC/LD505 can operate over a supply voltage range of 1.0 to 1.6 DC.
