Analog Switch

GT4851

The GT4851 is a CMOS analog IC configured as an 8- channel multiplexer. This CMOS device can operate from 2.5 V to 5.5 V. The GT4851 device are digitally-controlled analog switches. It has low on-resistance (22Ω TYP) and very low off-leakage current (1nA TYP). The GT4851 is available in Green SOP16, TSSOP16 and QFN-3×3-16L packages. It operates over an ambient temperature range of -40°C to +125°C.
