Variable-Gain Low-Noise Current Amplifier DLPCA-200

Packed with features the DLPCA-200 variable gain transimpedance amplifier is designed for a wide range of applications that require the conversion of small currents into usable voltages.

 

It is ideally suited, for time-resolved measurements down to the micro second region and as preamplifier for photodiodes or lock-in systems. The DLPCA-200 offers variable transimpedance gain from 103 to 1011 V/A allowing the sensitive measurement of currents in the sub-pico to milli amp range. Its switchable AC/DC coupling, 10 Hz low pass filter and adjustable offset control can be used to adapt the amplifier to varying measurement tasks and signal conditions. An adjustable bias voltage connected to the shield of the input socket is provided to optimise the speed and noise performance of external photodiodes connected to the amplifier input. All functions can be set either manually by switches or through the opto-isolated interface by remote control. The LUCI-10 is available as an additional product used as a USB interface. All this in a rugged and compact EMI shielded case designed with the user in mind and built to guarantee trouble-free operation even in very rough and noisy environments.

 

Applications include Photodiode and Photomultiplier Amplifier, Scanning Tunneling Microscopy (STM), Spectroscopy, Beam Monitoring for Particle Accelerators / Synchrotrons Ionization Detectors, Preamplifier for Lock-Ins, A/D-Converters etc, versatile low-noise amplifier.
