General Description
The HV2802 and HV2902 are low-charge injection,
32-channel, high-voltage analog switches intended for
use in applications requiring high-voltage switching
controlled by low-voltage control signals, such as
medical ultrasound imaging, driving piezoelectric
transducers and printers. The HV2902 has integrated
bleed resistors which eliminate voltage build-up on
capacitive loads such as piezoelectric transducers.
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 feedthrough 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 the
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.
