Detailed Description
The MAX4736 is a low 0.8Ω max (at V+ = 2.7V) onresis-
tance, low-voltage, dual SPDT analog switch that oper-
ates from a 1.6V to 4.2V single supply. CMOS switch
construction allows switching analog signals that range
from GND to V+.
When powered from a 2.7V supply, the 0.8Ω max RON
allows high continuous currents to be switched in a variety
of applications.
Applications Information
Proper power-supply sequencing is recommended for all
CMOS devices. Do not exceed the absolute maximum
ratings; stresses beyond the listed ratings can cause per-
manent damage to the devices. Always sequence V+ on
first, followed by NO_, NC_, or COM_.
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
propagation from the V+ supply to other components. A
0.1μF capacitor, connected from V+ to GND, is adequate
for most applications.
Logic Inputs
The MAX4736 logic inputs can be driven up to 3.6V,
regardless of the supply voltage. For example, with a 1.8V
supply, IN_ can be driven low to GND and high to 3.6V.
Driving IN_ rail-to-rail minimizes power consumption.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in
onresistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be used as either inputs or outputs.
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Reduce stray induc-
tance and capacitance by keeping traces short and wide.
Ensure that bypass capacitors are as close to the device
as possible. Use large ground planes where possible.
