GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG841-KGD is a low voltage CMOS device containing a
single-pole, single-throw (SPST) switch. The ADG841-KGD
is closed for a Logic 1 input. The device offers ultralow on
resistance of less than 0.48 Ω over the full temperature range.
The ADG841-KGD is fully specified for 3.3 V, 2.5 V, and 1.8 V
supply operation.
1.
2.
3.
Each switch conducts equally well in both directions when on,
and has an input signal range that extends to the supplies.
Additional application and technical information can be found
in the ADG841 data sheet.
Rev. B
4.
<0.48 Ω over full temperature range of −40°C to +125°C.
Compatible with 1.8 V CMOS logic.
High current handling capability
(300 mA continuous current at 3.3 V).
Low THD + N (0.02% typical).
