FEMTO DLPCA-200 impedance current amplifier PA class weak current signal
The DLPCA-200 variable gain amplifier is packaged according to its own characteristics and can be used in a wide range to convert small currents into usable voltages. It is ideal, for example, for solving current time and charge measurements into the microsecond region and as a preamplifier for photodiodes or lock-in systems. The DLPCA-200 offers variable gain values from 103 to 1011V/A, and allows current-sensitive measurements in the picomicroAMP series. There are switch-controlled AC/DC coupling, 10H2 low-pass filters and adjustable bias control sections used to change amplifiers for different measurement tasks and signal states with adjustable bias voltages connected to the input receptacle shield to provide optimized external diode connections to the amplifier circuit for input speed and noise performance.|
