HV2808

32-Channel Low Harmonic Distortion High-Voltage Analog Switch IC

Features

General Description

• 32-channel High-voltage Analog Switch

• 2:1 Multiplexer/demultiplexer

The HV2808 is a 32-channel low-harmonic-distortion

high-voltage analog switch integrated circuit designed

for medical ultrasound imaging systems as a probe

selection relay replacement. It serves as a 16-pole

double-throw (PDT) high-voltage analog switch array.

The device is a very fast transducer multiplexer that

consumes minimal power and emits no audible noise.

• 3.3V or 5V CMOS Input Logic Level

• –10 µA Low-quiescent Power Dissipation

• Low Parasitic Capacitance

• DC to 50 MHz Analog Signal Frequency

• –60 dB Typical Off-isolation at 5 MHz

• CMOS Logic Circuitry for Low Power

• Excellent Noise Immunity

This device combines high-voltage bilateral DMOS

switches and low-power CMOS logic to provide

efficient control of high-voltage analog signals. The

HV2808 is suitable for various combinations of

high-voltage supplies, such as V_PP/V_NN: +40V/–160V,

+100V/–100V and +160V/–40V.

• Flexible Operating Supply Voltages

Applications

Moreover,

comes

• Electromechanical Relay Replacement in Medical

Ultrasound Probes

8 mm x 8 mm x 1 mm 56-lead VQFN package.

Compared to an electromechanical relay, it does not

only save considerable PCB area but also

PCB-assembled height.
