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 R_ON 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 V_CC 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, V_IN, as low as 1.3 V for a V_CC of 3.0 V. The NLAS52231 is
offered in a very small 1.4mm x 1.8mm 10-pin UQFN package.
