Supertex Inc. has released the HV2605, HV2705 and HV2706, 16-channel analog switch ICs. The ICs incorporate HVCMOS technology that improves performance in applications using low voltage logic signals to control high voltage switching. Examples of these applications include medical ultrasound diagnostic imaging and non-destructive testing and evaluation.

The HV2705 includes built-in bleed resistors that minimize noise and reduce capacitive coupling. The HV2706 also features bleed resistors and has a different pin configuration than HV2705.

The ICs feature operating voltage up to 200V, which enables deeper body tissue imaging capability in ultrasound applications. Low quiescent power dissipation of -10?A ensures highly efficient operation and 22? switch resistance minimizes signal attenuation, resulting in clearer images.

The HV2605, HV2705 and HV2706 are available in 48-lead LQFP packages (HV2605FG-G, HV2705FG-G and HV2703FG-G). The parts are RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4C6 weeks ARO. Pricing is US$15.06 each for the HV2605FG-G, US$15.12 each for the HV2705FG-G and US$15.12 each for the HV2706FG-G, all in 1K quantities.
