Low-Voltage, Dual SPDT
Analog Switches in UCSP
MAX4684/MAX4685
General Description
The MAX4684/MAX4685 low on-resistance (R
ON
), low-
voltage, dual single-pole/double-throw (SPDT) analog
switches operate from a single +1.8V to +5.5V supply.
The MAX4684 features a 0.5鈩?(max) R
ON
for its NC
switch and a 0.8鈩?(max) R
ON
for its NO switch at a
+2.7V supply. The MAX4685 features a 0.8鈩?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
ON
= 50ns and t
OFF
= 40ns at +3V. The digi-
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)鈩? significantly reducing the required
PC board area. The chip occupies only a 2.0mm
鉁?/div>
1.50mm area. The 4

3 array of solder bumps are
spaced with a 0.5mm bump pitch.
