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