GENERAL DESCRIPTION
The ADG836 is a low voltage complementary metal-oxide
semiconductor (CMOS) device containing two independently
selectable single-pole, double-throw (SPDT) switches. This
device offers an ultralow on resistance of less than 0.8 Ω over
the full temperature range. The ADG836 is fully specified for
3.3 V, 2.5 V, and 1.8 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
ADG836 exhibits break-before-make switching action.
The ADG836 is available in a 10-lead MSOP and in a 3 mm ×
3 mm 12-lead LFCSP.
PRODUCT HIGHLIGHTS
1. <0.8 Ω over full temperature range of –40°C to +125°C.
2. Single 1.65 V to 3.6 V operation.
3. Compatible with 1.8 V CMOS logic.
4. High current handling capability (300 mA continuous
current at 3.3 V).
5. Low total harmonic distortion plus noise (THD + N)
(0.02% typical).
6. 3 mm × 3 mm LFCSP and 10-lead MSOP.
