4-to-1 RF Multiplexer
Overview
TI-RF-MUX is a 4-to-1 RF multiplexer designed with an internal current feedback output amplifier which gain can be adjusted externally. There is a possibility of optional usage of two 4-to-1 devices as a one 8-to-1 multiplexer. The device architecture allows to switch off the current source power that sufficiently reduces the quiescent current. ESD protection provided.
