Compact Video Driver Series for DSCs and Portable Devices
Compact,
Low Current Consumption
Single Output Video Drivers
BH76106HFV, BH76109HFV, BH76112HFV, BH76206HFV
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)
Applications
Mobile phone, DSC, DVC, DVD, and other

(11) SAG correction
In order to make the SAG of the video signal as small as possible, we recommend the values of the application circuit
diagram for output coupling capacitor capacitance.
If reducing capacitance due to the demands of miniaturization or the like, check the SAG characteristic for an
alternating black and white bounce signal *1, Hbar signal *2, or other signal for which a SAG effect readily occurs and
use a capacitance that satisfies the demands of the set being used.
As a reference, try the combinations shown below when reducing capacitance. As the capacitance of the VOUT
capacitor is made smaller, SAG becomes greater.

By eliminating the output coupling capacitor, not only can you reduce board space and product cost, but improvement
of the SAG characteristic also can be realized due to the fact that the low-band frequency characteristic is improved.
However, since direct current will flow in a set connected on the opposite side due to eliminating the output coupling
capacitor, pay close attention to the specifications of what is connected in conjunction with using it.
Moreover, characteristics such as circuit current, differential gain, and differential phase differ as shown below.

(13) Output dynamic range
The output dynamic range depends on the power supply voltage.
Be careful when using the LSI at low voltage.
The relationship of dynamic range to Vcc is shown in Fig. 19.
