Overview
The ADG904BCPZ-R-REEL is a wideband analog 4:1 multiplexer produced by Analog Devices Inc. This device utilizes a CMOS process to offer high isolation and low insertion loss up to 1 GHz. It is available in a 20-lead LFCSP (Lead Frame Chip Scale Package) and is designed for high-frequency switching applications. The ADG904BCPZ-R-REEL is a reflective multiplexer, contrasting with the absorptive/matched version of the ADG904. It features on-board CMOS control logic compatible with both CMOS and LVTTL inputs, eliminating the need for external control circuitry.
