AD8170/AD8174 is a chip with 250 MHz, 10 ns switching multiplexers and amplifiers. It features fully buffered inputs and outputs, fast channel switching, high output drive, flexible gain setting, high speed 250 MHz bandwidth, low power, etc.
The AD8170 (2:1) and AD8174 (4:1) are high‑speed buffered analog multiplexers with an internal current‑feedback amplifier. They offer 250 MHz bandwidth, 10 ns channel switching, and up to 50 mA output drive, making them suitable for video and other high‑speed applications. Power consumption is low, with typical quiescent current under 10 mA and a shutdown mode that reduces current to 1.5 mA.
The document includes detailed electrical specifications, absolute maximum ratings, ordering information for multiple package options, and a theory of operation that explains the internal switch architecture and biasing. Mechanical outline dimensions for the available 8‑lead and 14‑lead DIP and SOIC packages are also provided.
