ADM2486 Features
The ADM2486 contains a silicone dielectric gel which covers the silicon piezoresistive sensing element. The gel is a nontoxic, nonallergenic elastomer system which meets all USP XX Biological Testing Class V requirements. The properties of the gel allow it to transmit pressure uni- formly to the diaphragm surface, while isolating the internal electrical connections from the corrosive effects of fluids, such as saline solution. The gel provides electrical isolation sufficient to withstand defibrillation testing, as specified in the proposed Association for the Advancement of ADM2486edical Instrumentation (AAADM2486I) Standard for blood pressure trans- ducers. A biomedically approved opaque filler in the gel pre- vents bright operating room lights from affecting the performance of the sensor. The ADM2486 is a no--gel option.
ADM2486 Applicatioins
The SDA 9254-2 is a combination of the TV-SAM SDA 9253 and an adaptive recursive filter to achieve a reduction of noise for video signals. To get a closed loop one of the two output ports of the triple port memory is connected internally to the noise reduction filter. External access to this port is not possible. The characteristic of the noise reduction filter is adjustable via three pins (CLASS2, CLASS1, CLASS0).
