No. 15064EBT03
●Description
This video amplifier with built-in LPF uses a full output swing type output stage to make low voltage operation at Vcc = 2.6V possible. In addition to advantages such as a tiny package and low power consumption, bands of the built-in LPF provide for 4.5 MHz products for DSC and other portable equipment and 6 MHz products for equipment such as DVD. Moreover, since it also can be used at Vcc = 5 V, it is suited not only to portable equipment but also to equipment for stationary use.
●Features 1) Wide operating voltage range: Vcc = 2.6 V~5.5 V 2) Built-in 8th order LPF 3) Built-in sync-tip clamp circuit 4) Compact HVSOF6 package (3.0 mm × 1.6 mm × 0.75 mm) 5) Built-in standby function Standby current: 0 μA (typ.) 6) Selectable gain 6dB (BH76106HFV, BH76206HFV), 9dB (BH76109HFV), 12dB (BH76112HFV) 7) Selectable filter characteristics f = 4.5 MHz (BH761xxHFV), f = 6.0 MHz (BH76206HFV)

●Cautions on Use (1) Numeric values and data that are cited are representative design values and their values are not guaranteed. (2) Although we are confident recommending the application circuit example, carefully check the characteristics further in conjunction with its use. If using it after modifying externally attached component constants, try to determine adequate margins by including not just static characteristics but also transient characteristics to .
