GENERAL DESCRIPTION
The ADG799A/ADG799G are monolithic
CMOS devices comprising three 2 × 2 crosspoint switches controllable via a standard I2C serial interface. The
CMOS process provides ultralow power dissipation, yet offers high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range and wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide in...
