| Audio ICs 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 inductive load at 600mA. FAbsolute maximum ratings (Ta = 25_C) 3) Time delays can be created as needed with an external CR circuit. FInternal circuit schematic 829 Audio ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 9.0V) BA335 FMeasurement circuit 830 Audio ICs BA335 FAttached components C1 : Input coupling capacitor. 1 to 2.2F recommended. C2 : AC bypass capacitor. 0.1 to 0.47F recommended. R1, C3 : Resistor and capacitor for setting time delay. R2, C4 : Resistor and capacitor for ripple filter. FInput characteristics As shown in Fig. 4, VP6 and VP8 invert when the input reaches approximately *45dBm. VP8 is designed to be able to directly drive the NPN small signal transistor at this time. When on, VP6 is capable of accepting a maximum of 600mA of current (this will vary as shown in the duty cycle table). A continuous ON should last for no more than 3 seconds. Time delay using the hysteresis comparator is as follows. When an input signal of *45dBm or more goes to nothing ceases, the electrical potential of Pin 2 begins to fall due to the CR circuit connected to Pin 2. The time until the hysteresis comparator inverts is the time delay. When deciding the values of the capacitor and resistor, select a resistor value from 100 to 500k. 831 Audio ICs FElectrical characteristic curves BA335 FExternal dimensions (Units: mm) 832 |
