LD505

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.

The LD505 which is an eight pin device, has an internal 2.2 kW decoupling resistor for microphone bias providing increased supply line rejection. The base of the output transistor is also accessible allowing connection of diodes in a feedback configuration for peak limiting.
