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 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 absolute maximum ratings (Ta=25).The VCC Max (power supply voltage) is 8.0 V.The Pd (power dissipation) is 750 mW.The Topr (operating temperature) is from -25 to 75.The Tstg (storage temperature) is from -55 to 125.Then is about the recommended operating conditions (Ta=25).The minimum VCC (recommended operating voltage) is 4.5 V and the maximum is 5.5 V.
