●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.

1) Wide operating voltage range: Vcc = 2.6 V~5.5 V
th
2) Built-in 8 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.)

※The values show above (Voltage and resistance values) are reference values used for description, and are not guaranteed.
●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 take into account variations in
externally attached components and the ROHM LSI.
(3) Absolute maximum ratings
If absolute maximum ratings such as applied voltage and operating temperature range are exceeded, the IC may be
damaged. Do not apply voltages or temperatures that exceed the absolute maximum ratings. If you are considering
circumstances in which an absolute maximum rating would be exceeded, implement physical safety measures such as
fuses and investigate ways of not applying conditions exceeding absolute maximum ratings to the LSI.
(4) GND potential
Even if the voltage of the GND pin is left in an operating state, make it the minimum voltage. Actually confirm that the
voltage of each pin does not become a lower voltage than the GND pin, including for transient phenomena.
(5) Thermal design
Perform thermal design in which there are adequate margins by taking into account the allowable dissipation under
conditions of actual use.
(6) Shorts between pins and mounting errors
When mounting the LSI on a board, be careful of the direction of the LSI and of misalignment. If mounted badly and
current is passed though it, the LSI may be damaged. The LSI also may be damaged if shorted by a foreign
substance getting in between LSI pins, between a pin and the power supply, or between a pin and GND.
(7) Operation in a strong electromagnetic field
Since the LSI could malfunction if used in a strong electromagnetic field, evaluate this carefully.
(8) Input termination resistor
Since there is a risk of oscillation at low temperatures (approximately -60 °C) if the termination resistor of the input pin
is made high impedance, set it to no more than 700 Ω.

(9) Standby pin
When the standby pin is open, the LSI is in a standby state.
Since adding a voltage greater than Vcc at the standby pin turns a protective diode ON, make this at most Vcc+0.2 V
(no greater than Vcc+VF). (See Fig. 4) Applying a voltage to the standby pin when the voltage Vcc is not being
applied also turns the protective diode ON, so do not apply a voltage.

(10) Input coupling capacitor
Making the input coupling capacitor a value less than 0.1 μF (the recommended value) increases SAG. Determine
the capacitance of the input capacitor used after taking into consideration the relationship of SAG to input coupling
capacitor.

Moreover, if you make the input coupling capacitor a value greater than 0.1 μF (the recommended value), it may take
time for the output waveform to stabilize. Decide the value of the coupling capacitor used by referring to the results

(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.

(14) Bypass capacitor
Since there is a risk of high frequency oscillation, position the power supply bypass capacitor as close as possible to
the Vcc pin.
(15) Metal part of back of package
The metal part of the back of the package of this IC also serves as a heat sink. Since it is connected to the GND of
the IC, when mounting the IC, connect it to GND or make it NC.
Moreover, since there is a risk of shorting, avoid passing a wire other than a GND under the IC.
