General Description
The Supertex 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.
Input data are shifted into a 32-bit shift registers that can then be
retained in a 32-bit latch. To reduce any possible clock feed through
noise, the latch enable bar should be left high until all bits are clocked
in. Data are clocked in during the rising edge of the clock. Using
HVCMOS technology, this device combines high voltage bilateral
DMOS switches and low power CMOS logic to provide efficient control
of high voltage analog signals.
The device is suitable for various combinations of high voltage
supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.
