GENERAL DESCRIPTION
The ADG801/ADG802 are monolithic CMOS SPST (Single
Pole, Single Throw) switches with On Resistance of less than
0.5. These switches are designed on an advanced submicron
process that provides extremely low on resistance, high switch-
ing speed and low leakage currents.
The low On Resistance of <0.5means these parts are ideal
for applications where low on resistance switching is critical.
The ADG801 is a normally open (NO) switch, while the
ADG802 is normally closed (NC). Each switch conducts
equally well in both directions when ON.
The ADG801 and ADG802 are available in 6-lead SOT-23
and 8 Lead µSOIC packages.
PRODUCT HIGHLIGHTS
1. Low On Resistance (0.25 typical).
2. +1.8V to +5.5V Single Supply Operation.
3. Tiny 6 Lead SOT23 and 8 Lead µSOIC Packages.
4. Pin Compatible with ADG701 (ADG801)
Pin Compatible with ADG702 (ADG802).
