Low Harmonic Distortion, 32-Channel,

High Voltage Analog Switch Relay Replacement IC

General Description

Features

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.

► 32-channel high voltage analog switch

► 2:1 multiplexer/demultiplexer

► Enable control for all-OFF state

► 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

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.

► Flexible operating supply voltages

► 56-Lead 8x8 QFN package

The device is suitable for various combinations of high voltage

supplies, e.g., V_PP/V_NN: +40V/-160V, +100V/-100V, and +160V/-40V.

Applications

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.

► Electromechanical relay replacement in

medical ultrasound probes.
