LT505 DATA SHEET
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 k
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 74dB. Due to low power consumption
this part is the perfect choice for the output
stage of class A hearing instruments.
