в–єв–є Piezoelectric transducer drivers The Supertex HV232 is a low charge injection 8-channel,
high-voltage, analog switch integrated circuit (IC) with bleed
resistors. This device can be used in applications requiring
high voltage switching controlled by low voltage control
signals, such as ultrasound imaging and printers. The bleed
resistors eliminate voltage built up on capacitive loads such
as piezoelectric transducers. Input data is shifted into an 8-bit
shift register which can then be retained in an 8-bit latch. To …
