HV2901 is a low charge injection 32-channel high voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. The bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers.
