Description

The RC6334 consists of four low power, wide band voltage
feedback operational amplifiers. Each channel is capable of
delivering a load current of at least 35mA.

The amplifiers are optimized for video applications where
low differential gain and low phase distortion are significant
requirements.

Applications

• RGB amplifiers

• Video instrumentation amplifier

• Selectable gain amplifier

• Active filters

• Set-top box Buffers/Drivers
