0.5 OHM, DUAL SPDT ANALOG SWITCH Description
The IDTAS4684 low on-resistance (RON), low voltage, dual single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4684 features a 0.5 (max) RON for its NC switch and a 0.8 (max) RON for its NO switch at a +2.7 V supply. It also features break-before-make switching action (2 ns) with tON = 50 ns and tOFF = 40 ns at +3 V. The digital logic inputs are 1.8 V logic-compatible with a +2.7 V to +3.3 V supply. Comes in a 12-bump CSP package.
