2.5Ω, Low-Voltage, SPST/SPDT
Analog Switches in UCSP Package
General Description
The MAX4686/MAX4687/MAX4688 low on-resistance
(R_ON), low-voltage analog switches operate from a sin-
gle +1.8V to +5.5V supply. The MAX4686/MAX4687 are
single-pole/single-throw (SPST) analog switches, and
the MAX4688 is a single-pole/double-throw (SPDT) ana-
log switch. The MAX4686 is a normally open (NO)
switch, and the MAX4687 is a normally closed (NC)
switch. The MAX4688 has one normally open (NO)
switch and one normally closed (NC) switch.
When powered from a 3V supply these devices feature
2.5Ω (max) R_ON, with 0.4Ω (max) R_ON matching and 1Ω
(max) flatness. The MAX4686/MAX4687/MAX4688 offer
fast switching speeds (t_ON = 30ns max, t_OFF = 12ns
max). The MAX4688 offers break-before-make action.
The digital logic inputs are 1.8V logic compatible from a
+2.7V to +3.3V supply. The MAX4686/MAX4687/
MAX4688 are available in the chip-scale package
(UCSP™), significantly reducing the required PC board
area. The chip occupies only a 1.50mm x 1.02mm area.
The 3 x 2 array of solder bumps are spaced with a
0.5mm bump pitch.
