音频电平传感器 Audio level sensor
The is a sensor amplifier which consists of three blocks : a small signal audio amplifier, a hysteresis comparator, and a driver. Housed in a 9-pin SIP package, it is optimal for tape recorder end detection and tape mute detection.
Features
1 Built-in comparator with stable hysteresis under power supply voltage and temperature fluctuations.
2 Built-in transistor and diode capable of driving an inductive load at 600mA.
3 Time delays can be created as needed with an external CR circuit.
