Model：5325 Country of Origin：Japan
Category：Precision Bipolar Power Amplifier
The 5325 is a high-voltage-resistant, low-noise, wide-band isolation amplifier that provides electrical isolation between input and output. It is suitable for detecting signals at high voltages, for interfacing between devices with different reference potentials, and for measures such as preventing noise signals from computers at the input of measuring instruments (ground separation).
