0.5 OHM, DUAL SPDT ANALOG SWITCH
PRELIMINARY DATASHEET
IDTAS4684A
Description
The IDTAS4684A 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
IDTAS4684A 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.
