General Description
The Supertex HV2801 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.
Input data are shifted into a 32-bit shift register 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.
