NLAS52231数据手册ONSEMI中文资料规格书

描述 Description

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 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.
