12-ns DG611 Switch Family Combines Benefits of CMOS and DMOS Technologies

The DG611, DG612, and DG613 are extremely low-power, high-speed analog switches designed to optimize circuit performance in high-speed switching applications. Each of these devices integrates low-power CMOS drivers with high-speed DMOS FETs. The resulting switches boast some remarkable features: high speed, low power, low on-resistance, low leakage, low charge injection and low channel capacitance, all on the same device.

By combining both CMOS and DMOS technologies on a single chip, the DG61X family avoids the tradeoffs inherent in other high-speed analog switches, such as high power consumption, high on-resistance, and high channel capacitance. The DG61X family is likewise superior to DMOS FETs, which are fast but highly sensitive to electrostatic discharge, as well as requiring external drivers built with a number of external discrete components.
