Standard 3-output
Video Driver
BA7622F, BA7623F
No.09065EAT04
●Description
The BA7622F and BA7623F are video driver ICs with three built-in circuits, developed for video equipment. The three circuits
in the BA7622F, two sync-tip clamp inputs and one bias input, are terminated by internal resistances of 20 kΩ. The BA7623F
output pins cab be connected directly in a DC coupling mode. Each output can drive 2 lines of load (75Ωx2).
Suitable to connect to a 2Vpp output type signal processing LSI and DAC.
●Features
Common
1) 2 lines can be driven from each output
2) Can be operated by Vcc=4.5 V
BA7622F
1) Large output dynamic range (3.3 Vpp, Vcc=5 V)
2) Built-in, 2 clamp input circuits and1 bias input circuit
3) Y signal, C signal, and composite video signal can be driven simultaneously by this particular IC.
BA7623F
1) Wide output dynamic range (3.3 Vpp, Vcc=5 V)
2) Can be directly connected to previous stage circuit
●Applications
TV, VCR, camcorder, and other video equipment.

Connect a distortion meter to the output. Apply a f=1 kHz, 1 Vp-p sine wave to the input and adjust the input level so that the output distortion becomes 1.0%.
The maximum output level Vom (Vp-p) is the output voltage at that time.
＊ 2：Voltage gain
Apply a f=1MHz, 2.0 Vp-p sine wave to the input.. The voltage gain GV=20log[VOUT/VIN] (dB).
＊ 3：Input resistance
Measure the input pin voltage VIN50, when 50 μA is injected at the input pin. Measure the open voltage VIN0 of the input pin.
The input resistance Z=( VIN50- VIN0)/50×10-6 [Ω].
＊ 4：Total harmonic distortion
Apply a f=1kHz, 1.0 Vp-p sine wave to the input and measure by connecting a distortion meter to the output.

Technical Note

●Operation Notes
1. Numbers and data in entries are representative design values and are not guaranteed values of the items.
2. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to
verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits
may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow
for sufficient margins when determining circuit constants.
3. Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range
(Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open
mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using
the IC at times where the absolute maximum ratings may be exceeded.
4. GND potential
Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the
GND at any time, regardless of whether it is a transient signal or not.
5. Thermal design
Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd)
in actual states of use.
6. Short circuit between terminals and erroneous mounting
Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other
components on the circuits, can damage the IC.
7. Operation in strong electromagnetic field
Using the ICs in a strong electromagnetic field can cause operation malfunction.
