NLAS52231

Ultra-Low 0.4 W

Dual SPDT Analog Switch

with Overshoot

The NLAS52231 is a dual SPDT analog switch with overshoot

capability on the signal lines. It is ideally suited for audio applications

that require very low RON values for maximum signal transfer. The

overshoot feature 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 VCC 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.

Features

• Ultra-Low RON: 0.4 W at VCC = 4.2 V

• Overshoot Capability: VIS can safely rise up to 1.1 V above VCC

• VCC Range: 1.65 V to 4.5 V

• 1.4 x 1.8 x 0.55 mm UQFN10

• These are Pb-Free Devices

Typical Applications

• Mobile Phones

• Portable Devices
