Description
The RC6303 consists of three low power, wide band voltage
feedback operational amplifiers. Each channel is capable of
delivering a load current of at least 35mA. Each amplifier
can be independently enabled or disabled with a TTL or
CMOS signal. When disabled, the amplifier is in a high
impedance output state, presenting a very high input to out-
put isolation.
The amplifiers are optimized for video applications with gain
³ 2 where low differential gain and low phase distortion are
significant requirements.
The layout is optimized for minimal crosstalk between
amplifiers.
