The Supertex HV2808 is a low harmonic distortion, 32-channel,
high voltage analog switch integrated circuit (IC), designed for
use in medical ultrasound imaging systems as a probe selection
relay replacement. It serves as a 16PDT (16-pole, double throw)
high voltage analog switch array. HV2808 is a very fast transducer
multiplexer that consumes minimal power and emits no audible
noise.
32 Channels of high voltage analog switch
2:1 Multiplexer / Demultiplexer
3.3 or 5.0V CMOS input logic level
HVCMOS technology for high performance
Very low quiescent power dissipation -10µA
Low parasitic capacitance
DC to 50MHz analog signal frequency
-60dB typical OFF-isolation at 5.0MHz
CMOS logic circuitry for low power
Excellent noise immunity
Flexible operating supply voltages
Using 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.
Applications
►► Electromechanical relay replacement in
medical ultrasound probes.
The HV2808 comes in an 8x8x1.0mm, 56-Lead QFN package.
Compared to an electromechanical relay, it not only saves
considerable PCB area, but also saves on the PCB assembled
height.

2. VSIG must be VNN ≤ VSIG ≤ VPP or floating during power up/down transition.
3. Rise and fall times of power supplies VDD, VPP, and VNN should not be less than 1.0msec.
