CXA1910Q

Operation mode control (INSW, AUXSW, TAPESW, DRSW, NRSW, MSSW, MODESW)

The CXA1910Q has built in electronic switch circuits and the operations are controlled by the direct current

applied to each SW pin. The operation mode state for each switch is shown in the table below.

Click noise can be reduced by the external CR time constant circuit for NR SW switching.
