The ADV3221/ADV3222 include an output buffer that can be placed into a high impedance state. This allows multiple outputs to be connected together for cascading stages without the off channels loading the output bus. The ADV3221 has a gain of +1, and the ADV3222 has a gain of +2, they both operate on +/-5V supplies while consuming less than 7.5mA of idle current. The channel switching is performed via latched control lines, allowing synchronous updating in a multiple ADV3221/ADV3222 environment.
The ADV3221/ADV3222 are offered in a 16-lead SOIC package and are available over the extended industrial temperature range of -40°C to +85°C.
