Low-Resistance DPDT Switches
with Negative Rail
General Description
The MAX14535E–MAX14539E are low on-resistance
and high ESD-protected DPDT switches that multiplex
analog signals, such as AC-coupled audio or video.
These devices combine the low on-capacitance (C_ON)
and low on-resistance (R_ON) necessary for high-perfor-
mance switching applications in portable electronics,
and include an internal negative supply to pass audio
signals that swing below ground (down to -1.5V).
The MAX14535E/MAX14537E/MAX14539E feature inter-
nal shunt resistors on the normally open path (and nor-
mally closed path, (MAX14539E)) to reduce clicks and
pops heard at the output. The MAX14535E–
MAX14539E have an enable input (EN) to reduce sup-
ply current and set all channels to high-impedance
when driven low. When EN is driven low, the
MAX14537E/MAX14538E have the lowest possible cur-
rent consumption, but cannot withstand negative rail
signals. The MAX14535E/MAX14536E/MAX14539E can
still withstand a negative signal to NC_, NO_, or COM_
from -1.5V to min (V_CC, 3V.)
The MAX14535E–MAX14539E operate from a +2.4V to
+5.5V supply. These devices can be powered from the
typical analog supply voltage in a cell phone (+2.5V to
+2.8V) or a lithium-ion (Li+) battery (about 4.3V max).
The MAX14535E–MAX14539E have high ESD protec-
tion, up to ±15kV on COM_, and the NC_, NO_, and
COM_ voltage can go up to 3.6V when V_CC = 0 without
damaging the devices.
All devices are offered in a space-saving, 10-pin,
1.4mm x 1.8mm UTQFN package, and operate over the
-40°C to +85°C extended temperature range.
