The ABLIC S-UM6522E is a low charge injection 32-channel single-pole, single-throw (SPST) high-voltage analog switch IC operated only by a single 5V for ultrasound imaging applications. Users can select either Serial Digital Interface (SDI) or Bank Interface. The S-UM6522E has the same packaging and pinout as the HDL6M06522BN with improved Con/Coff and off isolation performance.
