Description
The RC6704 consists of three low power, wide band voltage
feedback operational amplifiers. Internal thin-film gain set-
ting resistors provide gains of +2, +1 and -1. 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 output isolation. The layout is optimized for low
channel to channel crosstalk.
The amplifiers are optimized for video applications where
low differential gain and low phase distortion are significant
requirements.
