Audio level sensor

BA335

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.

FApplications

Tape end detection

Tape mute detection

FFeatures

1) Built-in comparator with stable hysteresis under

power supply voltage and temperature fluctuations.

2) Built-in transistor and diode capable of driving an in-

ductive load at 600mA.

3) Time delays can be created as needed with an exter-

nal CR circuit.
