PRODUCT HIGHLIGHTS
1. 0.6 Ω over full temperature range of –40°C to +125°C.
2. Compatible with 1.8 V CMOS logic.
3. High current handling capability (300 mA continuous
current at 3.3 V).
4. Low THD + N (0.01% typ).
5. Tiny SC70 package.
GENERAL DESCRIPTION
The ADG839 is a low voltage CMOS device containing a single-
pole, double-throw (SPDT) switch. This device offers ultralow
on resistance of less than 0.6 Ω over the full temperature range.
The ADG839 is fully specified for 1.8 V, 2.5 V, and 3.3 V supply
operation.
Each switch conducts equally well in both directions when on
and has an input signal range that extends to the supplies. The
ADG839 exhibits break-before-make switching action.
The ADG839 is available in a 6-lead SC70 package.
