NLAS52231

NLAS52231
Ultra-Low 0.4 W
Dual SPDT Analog Switch
with Overshoot Protection
The NLAS52231 is a dual SPDT analog switch with overshoot
protection on the signal lines. It is ideally suited for audio applications
that require very low RON values for maximum signal transfer. The
overshoot protection included in the NLAS52231 allows analog
signals on the COM, NO or NC lines to swing safely above VCC
without incurring significant leakage. This feature provides added
protection against undesirable leakage or damage to the device in the
event that an incoming audio signal spikes above its nominal level.
The NLAS52231 features a wide V CC operating range,
1.65 V−4.5 V. It is capable of interfacing with control input select line
voltages, VIN, as low as 1.3 V for a VCC of 3.0 V. The NLAS52231 is
offered in a very small 1.4mm x 1.8mm 10−pin UQFN package.

DETAILED DESCRIPTION
Overshoot Protection
also helpful in designs that pair a moderate signal swing
range with a fairly low operating voltage. Up to 1.1 V above
VCC, the NLAS52231 switch will pass signals without
distortion and maintain all specified performance
characteristics.
The NLAS52231 features overshoot protection on the
signal lines. This allows input signals to exceed the VCC
voltage of the switch up to 1.1 V. This is useful in
applications where the input signal has a wide dynamic
range and may at times exceed the typical signal swing. It is
