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.
