Description

The AS1746 is a low on-resistance (RON), low-voltage, dual-single-pole/double-throw (SPDT) analog switch designed to operate from a single +1.8 to +5.5V supply.

The device features a 0.5Ω (max) RON for normally closed (NC) switches and a 0.6Ω (max) RON for normally open (NO) switches using a +2.7V supply. Additionally the AS1746 offers excellent matching between channels of only 0.06Ω and the flatness over signal Range of 0.15Ω enables the device to provide a THD+N of only 0.025%.

The AS1746 features break-before-make switching (2ns) with tON = 50ns and tOFF = 30ns (using a +2.7V supply).

The digital logic inputs are 1.8V logic-compatible with +2.7 to +3.3V supplies.
