GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG852 is a low voltage CMOS single-pole, double-throw
(SPDT) switch. This device offers ultralow on resistance of less
than 1 Ω over the full temperature range. The ADG852 is fully
specified for 5.5 V and 3.3 V supply operation.
1.
<1 Ω over full temperature range of −40°C to +85°C.
2.
Single 2.3 V to 5.5 V operation.
3.
Compatible with 1.8 V CMOS logic.
4.
High current handling capability (300 mA continuous
current per channel).
5.
Low THD + N: 0.08% typical.
6.
1.30 mm × 1.60 mm, 10-lead mini LFCSP.
Each switch conducts equally well in both directions when on,
and has an input signal range that extends to the supplies. The
ADG852 exhibits break-before-make switching action.
The ADG852 is available in a 1.30 mm × 1.60 mm 10-lead
mini LFCSP.
