The PC810 is a tranimpedance preamplifier with a FET input that is fully protected against high voltage transients. Excellent gain stability is achieved with the use of low temperature coefficient components and high open to closed loop gain ratios throughout.</B></div> <bR> <div> <B>FEATURES</B></div> <bR> <div> <B>     - easily adjustable transimpedance          - floating return connections</B></div> <div> <B>     - count rates to 100 million/second           - low power consumption</B></div> <div> <B>     - single point grounding                              - standard footprint</B></div> <bR> <div> <B>SPECIFICATIONS</B></div> <bR> <div> <B>     Input Impedance                                            50 ohms nominal</B></div> <div> <B>    </B></div> <div> <B>     Input Level                                                       DC - 2KV</B></div> <bR> <div> <B>     Transimpedance                                            100 K maximum, adjustable to 1 K</B></div> <bR> <div> <B>     Output Level                                                    10 volts peak to peak maximum unterminated</B></div> <div> <B>                                                                                  1.5 volts peak to peak into 50 ohms</B></div> <bR> <div> <B>     Output Impedance                                          50 ohms nominal</B></div> <bR> <div> <B>     Output Risetime                                              Less than 4 nS</B></div> <bR> <div> <B>     Av Temperature Coefficient                         150 ppm/ degree C standard</B></div> <bR> <div> <B>     Broadband Input Noise                                Less than 25nA DC to 100 mHz, input and output open circuit</B></div> <bR> <div> <B>     Operating Temperature                                -20 to +55 degrees C</B></div> <bR> <div> <B>     Power Requirements                                    +12V at 60 mA, -12V at 52 mA</B></div> <div> <B> </B></div> <div> <B>     Power Cable                                                   1 meter twisted shielded pair</B></div> <bR> <div> <B>     </B><B>Size (L x W x H)                                              4.28" x 2.63" x 1.73"</B></div> <div> <B>                                                                                 (10.9cm x 6.9cm x 4.4cm)</B></div> <bR> <div> <A HREF="id17.htm" TARGET="_top" TITLE="Contact Us"><U><B>Contact us</B></U></A></div> <bR> <div> <B>Back to </B><FONT SIZE="3" COLOR="#0000FF" FACE="Arial" ><A HREF="id83.htm" TARGET="_top" TITLE="Nuclear/Photometric Instruments"><U><B>index</B></U></A></FONT></div> <bR> <bR> </td> </tr></table></body>
