Description
HV2601/HV2701 are low-charge injection, 16-channel,
high-voltage analog switch integrated circuits (ICs).
These devices are designed for use in applications
requiring high-voltage switching controlled by low-volt-
age control signals, such as medical ultrasound imag-
ing and other piezoelectric transducer drivers. HV2701
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 is
clocked in during the rising edge of the clock. Using
High-Voltage CMOS 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., V_PP/V_NN: +40V/-160V, +100V/-
100V, and +160V/-40V.
