The MAX4684/MAX4685 low on-resistance (R

voltage, dual single-pole/double-throw (SPDT) analog

switches operate from a single +1.8V to +5.5V supply.

The MAX4684 features a 0.5Ω (max) R

switch and a 0.8Ω (max) R

+2.7V supply. The MAX4685 features a 0.8Ω max on-

resistance for both NO and NC switches at a +2.7V

supply.

Both parts feature break-before-make switching action

(2ns) with t

tal logic inputs are 1.8V logic-compatible with a +2.7V to

+3.3V supply.

The MAX4684/MAX4685 are packaged in the chipscale

package (UCSP)™, significantly reducing the required

PC board area. The chip occupies only a 2.0mm

1.50mm area. The 4

spaced with a 0.5mm bump pitch.
