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 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 Protection: 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 Audio Terminal NLAS52231 AUDIO Source #1 AUDIO Source #2 Figure 1.
