MAX14589E/MAX14594E
High-Density, ±5V Capable DPDT Analog Switches
General Description
The MAX14589E/MAX14594E high-density, double-pole/
double-throw (DPDT) analog switches feature Beyond-
the-Rails™ capability that allows signals from -5.5V to
+5.5V to pass without distortion even when the power
supply is below the signal range. The low R_ON resistance
(0.2I) makes the devices ideal for low-distortion switch-
ing, such as audio.
The MAX14594E has internal shunt switches that
discharge the audio amplifier AC-coupling capacitance
at the normally open (NO1 and NO2) terminals. This
feature reduces click-and-pop sounds that occur when
switching audio signals between precharged points.
The switches are fully specified to operate from a single
+1.6V to +5.5V power supply. Because of the low supply
current requirement, V_CCEN can be provided by a GPIO.
When the power is not applied, switches go to a high-
impedance mode and all analog signal ports can with-
stand signals from -5.5V to +5.5V. The devices control
the switches with a control bit, CB.
The MAX14589E/MAX14594E are available in a 1.2mm
x 1.2mm, 0.4mm pitch, 9-bump wafer-level package
(WLP), and operate over the -40NC to +85NC extended
temperature range.
