NLAS52231MUR2G

NLAS52231 Analog Switch, Dual SPDT, Ultra-Low Ron, 0.4 W 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. http://onsemi.com MARKING DIAGRAM 1 S2 M G Features • • • • • Ultra−Low RON: 0.4  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 UQFN10 CASE 488AT = Specific Device Code = Date Code/Assembly Location = Pb−Free Device (Note: Microdot may be in either location) GND 7 6 8 5 NC1 COM2 9 4 IN1 10 3 COM1 NLAS52231 AUDIO Source #1 AUDIO Source #2 NC2 IN2 NO2 Audio Terminal S2MG G 1 2 VCC NO1 FUNCTION TABLE IN 1, 2 NO 1, 2 NC 1, 2 0 1 OFF ON ON OFF ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 8 of this data sheet.

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 Overshoot Max: VCC + 1.1 V VCC I/O Signal or Any NCx, NOx or COMx Pin GND Figure 13.
