BA7043FS

The BA7043FS is an auto tracking interface IC for VHS video cassette recorders that operates by detecting the playback RF signal.When FM audio or video signals are input,the IC products the peak detector output,the intergrated waveform or the peak hold voltage.

There are some features BA7043FS as follows.First,it reduces the load on the auto tracking microprocessor.The second is internal switching and processing for audio and video FM signals.Besides,gain can be internally switched to suit the mode (video,audio,EP or SP).Furthermore,it is possible to intergrate one frame,sample and hold to output the peak value.Fifthly,the output level is compressed to expand the dynamic range of the input.The last one is peak detection output and detection level down terminals provided.

What comes next is about the BA7043FS absolute maximum ratings (T_a=25).The V_{CC Max} (power supply voltage) is 8.0 V.The P_d (power dissipation) is 750 mW.The T_opr (operating temperature) is from -25 to 75.The T_stg (storage temperature) is from -55 to 125.Then is about the recommended operating conditions (T_a=25).The minimum V_CC (recommended operating voltage) is 4.5 V and the maximum is 5.5 V.
