Lock-in Amplifier/Preamplifier
Wideband Current Amplifier
SA-600 Series

High Gain, Broad Bandwidth and Stable Operation

SA-600 Series is a wideband current amplifier (current to voltage converter) with a high gain and wide frequency band. There are the following four types depending on the gain.
It operates stably for the added input capacitance despite a wide frequency band. It operates without oscillation with an added input capacitance of 1000 pF. The LPF cutoff frequency can be selected from four steps with a switch.
