GT4899
The GT4899 is a high-speed, low-voltage, dual-independent double-pole double-throw (DPDT) COMS analog switch that is designed to operate from a single +1.65V to +5.5V power supply. It features high-bandwidth (350 MHz) and low onresistance (3.5 Ω @ 4.5 V). The GT4899 is configured as a DPDT device with two logic control inputs that control two multiplexer/demultiplexer each. The configuration can also be used as a dual differential 2-to-1 multiplexer/demultiplexer. GT4899 is available in QFN-3×3-16L and UTQFN1.8×2.6- 16L.
