Current, Peak Limiting Class Amplifier
LT505 DATA SHEET
FEATURES amplifier current typically transducer current typically Schottky diodes provide peak limiting parts count gain 74dB typically with supply
DESCRIPTION LT505 current, voltage monolithic integrated circuit amplifier. comprised operational amplifier driving single transistor class output stage with open collector. Also included pair complementary Schottky diodes which, when shunted across load, provide capability symmetrical peak clipping. input stage biased external resistor. important that this resistor tolerance optimum performance. internal negative feedback loop ensures stable operating point output stage over designed operating voltage. Because lowered idle current, trimming output current with single external resistor recommended LT505. typical gain this power consumption this part perfect choice output stage class hearing instruments.
