Overview
The ADV3221ARZ, produced by Analog Devices Inc., is a high-speed, high-slew-rate, buffered 4:1 analog multiplexer. It is designed to offer excellent AC performance, making it ideal for various high-speed signal switching applications. The ADV3221 is a pin-for-pin upgrade to the HA4344 and operates on ±5 V supplies, consuming less than 7.5 mA of idle current. It is available in a 16-lead SOIC package and supports an extended industrial temperature range of −40°C to +85°C.
