Description

The LT505 is a low current, low voltage monolithic integrated circuit amplifier. It is comprised of an operational amplifier driving a single transistor class A output stage with open collector. Also included is a pair of complementary Schottky diodes which, when shunted across the load, provide the capability for symmetrical peak clipping. The input stage is biased by an external 200 kW resistor. It is important that this resistor be ±1% tolerance for optimum performance.

An internal negative feedback loop ensures a stable operating point for the output stage over the designed operating voltage. Because of the lowered idle current, trimming the output current with the use of a single external resistor is not recommended for the LT505. The typical gain for this IC is 74 dB. Due to low power consumption this part is the perfect choice for the output stage of class A hearing instruments.
