Datasheet
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.
