GENERAL DESCRIPTION
The ADG849 is a monolithic, CMOS SPDT (single pole, double
throw) switch that operates with a supply range of 1.8 V to 5.5 V.
It is designed to offer ultralow on-resistance values of typically
0.5 Ω. This design makes the ADG849 an ideal solution for
applications that require minimal distortion through the switch.
The ADG849 also has the capability of carrying large amounts
of current, typically 600 mA at 5 V operation.
Each switch of the ADG849 conducts equally well in both
directions when on. The device exhibits break-before-make
switching action, thus preventing momentary shorting when
switching channels.
The ADG849 is available in a tiny, 6-lead SC70 package, making
it the ideal candidate for space-constrained applications.
PRODUCT HIGHLIGHTS
1. Very low on-resistance, 0.5 Ω typical.
2. Tiny, 6-lead SC70 package.
3. Low power dissipation. The CMOS construction ensures
low power dissipation.
4. High current carrying capability.
5. Low THD + noise (0.01% typ).
