BA7047S

The BA7047S is a microcomputor-interface IC for VCR auto-tracking.It includes two input amplifiers,a peak detector circuit,output amplifiers and a comparator timing circuit.The IC outputs the peak detection output for input video and audio FM signals.

There are some BA7047S features as follows.First,the inverting input pin and internal switch allow construction of different types of filters.Secondly,built-in output switching allows both audio and video signals to be processed using one A/D port.Besides,a built-in comparator detects presence or absence of Hi-Fi audio.At last,a timing circuit suppresses the effects of head switching noise.

What comes next is about the BA7047S absolute maximum ratings (T_a=25).The V_CC (applied voltage) is 8.0 V.The P_d (power dissipation) is 500 mW.The T_opr (operating temperature) is from -25 to 70.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,the typical is 5.0 V and the maximum is 5.5 V.
