RT9737
5V Capable Low-Voltage DPDT Analog Switch
General Description
RT9737 is a 5V high quality low-voltage double-pole
double-throw (DPDT) analog switch. RT9737 supply
voltage is designed to operate from 2.5V to 5.5V.
Supply voltage can be smaller than input voltage while
keeping 5V input range. With 70m turn-on resistance,
power-loss and signal distortion can be minimized.
RT9737 is ideal for switching audio signal from outputs
of audio amplifiers. The break-before-make feature
prevents signal distortion during the transferring of a
signal from one path to another for audio applications.
