56-Lead 8x8 QFN package
The Supertex HV2809 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. The enable function allows the parts to be configured
as either a 2:1 or 4:1 multiplexer/demultiplexer. The HV2809 is a very
fast transducer multiplexer that consumes minimal power and emits
no audible noise.
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., V
PP
/V
NN
: +40V/-160V, +100V/-100V, and +160V/-40V.
The HV2809 comes in an 8.0mm x 8.0mm x 1.0mm, 56-Lead QFN
package. Compared to an electromechanical relay, it not only saves
considerable PCB area, but also saves on the PCB assembled height.
Applications
►
Electromechanical relay replacement in
medical ultrasound probes.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All
