Page 12: Overview
1.1 Overview Overview "SA-600 Series" is a wideband current amplifier (current to voltage converter) with a high gain and wide frequency band. There are the following five s depending on the gain. Model SA-604F2: Gain 10 MV/A, frequency band DC to 500 kHz... -
Page 13: Operating Principle
1.4 Operating Principle Operating Principle A1 is a inverting amplifier using a low noise FET for the first stage. SA-600 Series is designed so that the open loop gain is constant until the maximum operating frequency is reached, so the input impedance is a pure resistance and constant. - Page 14 <BLANK PAGE>...
