The BA335 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.
