The DG2011 is a low on-resistance, single-pole/double-throw monolithic CMOS analog switch. It is designed for low voltage applications with guaranteed operation at 2 V. The DG2011 is ideal for portable and battery powered equipment, requiring high performance and efficient use of board space. In additional to the low on-resistance (1.8 @ 2.7 V), charge injection is less than 10 pC over the entire analog range.
The switch conducts equally well in both directions when on,and blocks up to the power supply level when off.
