THS7303 is a low-power, single-supply, 2.7-V to 5-V,
3-channel integrated video buffer. It incorporates a
Selectable Input Bias Modes
selectable fifth-order Butterworth filter to eliminate

Low 16.6-mA (3.3 V) Total Quiscent Current
Each channel of the THS7303 is individually I2C

for any application. Its rail-to-rail output stage allows
for both ac and dc coupling applications. The 6-dB
– Output Swings within 100 mV from the
gain along with the built-in SAG correction allows for
Rails to Allow AC or DC Output Coupling
maximum flexibility as an output video buffer.
– Supports Driving Two Lines per Channel
The 16.6-mA total quiescent current (55 mW total
Low Differential Gain/Phase of 0.13%/0.55
°
power) makes the THS7303 an excellent choice for
USB powered or portable video applications. While
fully disabled, the THS7303 consumes less than 1
μA
making it ideal for energy sensitive applications.
