Low-Voltage, Dual SPDT, Audio Clickless
Switches with Negative Rail Capability
General Description
The MAX4744/MAX4744H/MAX4745/MAX4745H/
MAX4746H dual SPDT (single-pole/double-throw) audio
switches feature negative signal capability that allows
signals as low as V
CC
- 5.5V to pass through without
distortion. These analog switches have a low on-resis-
tance and low supply current, and operate from a single
+1.8V to +5.5V supply.
The MAX4744/MAX4744H have internal shunt resistors
that automatically discharge the capacitance at the nor-
mally open (NO) and normally closed (NC) terminals
when they are not connected. The MAX4746H features
internal shunt resistors on NC_ terminals. This reduces
click-and-pop sounds that occur when switching audio
signals between precharged points. A break-before-
make feature further reduces popping. The MAX4744/
MAX4745 control the switches with two control bits CB1
and CB2. The MAX4744H/MAX4745H/MAX4746H have
one control bit to switch both switches and an enable
input
EN
to put the switches in a high-impedance mode.
The MAX4744H/MAX4745H/MAX4746H also have an
internal protection network against voltages applied to
COM_ when V
CC
= 0V.
These devices are available in a space-saving 10-pin
µDFN (2mm x 2mm) package and operate over the
-40°C to +85°C extended temperature range.
