Product Details

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.


  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.
