Overview
The AD8170AR-REEL, produced by Analog Devices Inc., is a high-speed buffered multiplexer integrated with a current feedback amplifier. This device is available in an 8-pin SOIC package and is ROHS-compliant. It features a 2:1 multiplexer configuration, making it suitable for various high-speed applications requiring precise signal switching and amplification.
The AD8170 integrates wideband analog switches with a high-speed current feedback amplifier, offering a -3 dB signal bandwidth of 250 MHz and a slew rate greater than 1000 V/µs. This makes it ideal for applications that demand high signal integrity and fast switching times.
