SANTA ROSA, Calif. — Gain Current AmplifierThe DDPCA-300 ultralow, noise-variable, gain current amplifier from Femto has been announced by Electro Optical Components Inc.

Designed for sensitive current and charge measurements, the amplifier features a switchable gain from 104 to 1013 V/A. It has an extremely low noise input of 0.4 fA/√Hz minimum allowing measurement of currents in the femto to pico Ampere range. It also has a dynamic range of 240 dB. Features include adjustable voltage directly on amplifier input for DUT biasing, direct current-optimized design with high stability and very low drift and manual control and remote interface. It comes in a miniaturized, rugged aluminum housing that is designed to optimize EMI shielding. The small size allows users to get the amplifier close to the detector, minimizing noise from long detector leads.

The DDPCA-300 is the ideal tool for amplification of small currents close to direct current generated by high-impedance sources such as photodiodes, PMTs, ionization and particle detectors. Typical applications include spectroscopy, photodiode amplification, sensitive ionization and charge detector amplification, conductive atomic force microscopy, characterization of metal-oxide-semiconductor and field-effect transistor structures, quantum and biotech experiments, pre-amplification for oscilloscopes, analog-to-digital converters and digital voltmeters.
