Description
The HV2605 and HV2705 are 16-channel low
harmonic distortion high-voltage analog switch inte-
grated circuits (ICs). These devices are designed for
applications requiring high-voltage switching controlled
by low-voltage control signals, such as medical ultra-
sound imaging and other piezoelectric transducer driv-
ers. The HV2705 has integrated bleed resistors which
eliminate voltage build-up on capacitive loads such as
piezoelectric transducers.
These ICs shift input data into a 16-bit Shift register that
can then be retained in a 16-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. 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., V
PP

: +40V/–160V,
+100V/–100V and +160V/–40V.
