IC FOR PROXIMITY DETECTOR
GENERAL DESCRIPTION
AM 313
The AM 313 is a bipolar monolithic Integrated Circuit designed for proximity detection applications. The function is based on the damping of an LC oscillator which switches a
transistor and LED output.
FEATURES
Wide Supply Voltage Range from 4.75 to 35V Supply Current Without Oscillator typical 1mA Complementary Outputs with Short–Circuit Protection P–Type Drivers for
PNP Bipolar and PMOS
Transistors Adjustable Output Current From 100µA to 12mA Adjustable Detection Distance and Hysteresis Adjustable Temperature Compensation for Detection Distance Protection against False Polarity Power–On–Delay LED Output 4mA typical
