Tiny Analog Switches Work With Only 2.7V

Operating at voltages down to 2.7V, SPDT DG9431 and DG9461 provide signal routing and signal source selection functions in low-voltage systems, such as dual-band cellular phones, portable communicators, test equipment, and notebook PCs. The devices can operate from supplies ranging between 2.7V and 5V. Typical on-resistance is 30 ohms for the DG9431 and 50 ohms for the DG9461.
