General Description
The Supertex HV2301 is a low charge injection, 8-channel, high voltage analog switch integrated circuit (IC) with bleed resistors. The device can be used in applications requiring high voltage switching, controlled by low voltage control signals, such as medical ultrasound imaging, piezoelectric transducer driver, and printers. The built-in bleed resistors eliminate voltage built up on capacitive loads such as piezoelectric transducers. The HV2301 is an enhanced version of the HV232.
