High-Voltage Analog Switch
Features Description High-Voltage CMOS technology for high performance 16-channel high voltage analog switch 3.3V input logic level compatible 20 MHz data shift clock frequency Very low quiescent power dissipation (-10 ВµA) Low parasitic capacitance DC to 50 MHz small signal frequency response -60dB typical OFF-isolation at 5.0 MHz CMOS logic circuitry for low power Excellent noise immunity Cascadable serial data register with latches Flexible operating supply voltages Integrated bleed resistors on the outputs
(HV2701 only) 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-voltage control signals, such as medical ultrasound imaging and other piezoelectric transducer drivers. HV2701
has integrated bleed resistors which eliminate voltage
build-up on capacitive loads such as piezoelectric
transducers. Applications Medical ultrasound imaging
NDT metal flaw detection
Piezoelectric transducer drivers
Optical MEMS modules 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 …
