IDTAS4684_1 Datasheet, PDF (1/13 Pages) Integrated Device Technology – 0.5 OHM, DUAL SPDT ANALOG SWITCH

0.5 OHM, DUAL SPDT ANALOG SWITCH
DATASHEET
IDTAS4684
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 0.5Ω (max) RON for its NC switch and a 0.8Ω
(max) RON for its NO switch at a +2.7 V supply. It also
features break-before-make switching action (2 ns) with
t_ON = 50 ns and t_OFF = 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.
