BA7048N

The BA7048N is an auto tracking microcomputor interface device for VCRs.Using the audio or video FM signal,the IC generates a peak detection output for the FM signal.The IC consists of a peak detection circuit,FM input amplifier and an output amplifier.The typical applications include video cassette recorders (VHS format).

There are some BA7048N features as follows.First is available in SIP10 package.Secondly,various filters ca n be constructed using the inverted input pin and the built-in switch.Then is low voltage,typically 5V.The last one is low power consumption.

What comes next is about the BA7048N absolute maximum ratings (T_a=25).The V_CC (applied voltage) is 8.0 V.The P_d (power dissipation) is 850 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.

The following is about the BA7048N eletrical characteristics (T_a=25,V_CC=5.0 V).The minimum I_CC (supply current) is 3.5 mA,the typical is 5.5 mA and the maximum is 7.5 mA.The minimum G₆ (6 dB amplifier voltage gain) is 3.5 dB,the typical is 6.0 dB and the maximum is 8.0 dB at f=1.0 MHz,V_IN=0.5 Vpk-pk.The minimum f₆ (6 dB amplifier frequency characteristic) is -0.5 dB,the typical is +1.0 dB and the maximum is +2.5 dB at f=7.0 MHz/1.0 MHz,V_IN=0.5 Vpk-pk.The typical V₇ (detection characteristic 1) is 0.25 V and the maximum is 0.30 V at V_IN=0.0 Vpk-pk.The minimum V_7-1 (detection characteristic 2) is 0.90 V,the typical is 1.20 V and the maximum is 1.40 V at f=7.0 MHz,V_IN=1.0 Vpk-pk.The minimum V_th (switching voltage) is 1.00 V,the typical is 2.00 V and the maximum is 3.00 V.
