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.
