HV2605/HV2705
16-Channel Low Harmonic Distortion High-Voltage Analog Switches
Features Description 16-channel High-voltage Analog Switch Low Harmonic Distortion Integrated Bleed Resistors on the Outputs for
HV2705 3.3V Input Logic Level Compatible –60 dB typical OFF-isolation at 5 MHz 20 MHz Data Shift Clock Frequency 10 µA Low-quiescent Power Dissipation Low Parasitic Capacitance DC to 50 MHz Small-signal Frequency Response CMOS logic Circuitry for Low Power Cascadable Serial Data Register with Latches Flexible Operating Supply Voltages The HV2605 and HV2705 are 16-channel low
harmonic distortion high-voltage analog switch integrated circuits (ICs). These devices are designed for
applications requiring high-voltage switching controlled
by low-voltage control signals, such as medical ultrasound imaging and other piezoelectric transducer drivers. The HV2705 has integrated bleed resistors which
eliminate voltage build-up on capacitive loads such as
piezoelectric transducers. Applications 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 highvoltage supplies, e.g., VPP/VNN: +40V/–160V,
+100V/–100V and +160V/–40V. Medical Ultrasound Imaging
