The AD8112 is an audio/video crosspoint switch with a bandwidth of 60 MHz and a 16×8 configuration. It has a gain of +2 and is a low-cost, high-speed, nonblocking switch array. The switch array can be controlled through serial or parallel programming, and the serial data out allows daisy chaining control of multiple 16×8 arrays to create larger switch arrays. The output disable feature allows connection of multiple devices without loading the output bus. The AD8112 exhibits excellent audio and video performance, operates on ±5 V or ±12 V supplies, and has low supply current and wide bandwidth characteristics.
The AD8112 crosspoint switch matrix provides 16 × 8 routing with optional 16 × 16 expansion. It features low supply current, buffered inputs, and eight independent output amplifiers, making it suitable for audio and video routing applications such as CCTV, multimedia systems, and video conferencing.
The device is supplied in a 100‑lead LQFP package, operates over a commercial temperature range of 0 °C to 70 °C, and supports both serial and parallel programming for flexible control and daisy‑chaining of multiple arrays.
