10kHz Low Noise Transimpedance Amplifier LCA-10K-500M Preamplifier Module

The FEMTO microcurrent signal amplifier is a modular preamplifier that amplifies fA and nA level microcurrent signals obtained in laboratories and field applications by a factor of 10^2 to 10^13, converting current into voltage (transimpedance) for measurement via instruments or various devices.

To achieve extremely low noise levels, very high gain is required while minimizing the resulting bandwidth reduction. Therefore, Femto offers professional high-tech current amplifiers. The noise characteristics of our products are superior to current-to-voltage converters using OpAmps in corresponding frequency bands. Bandwidth and frequency response are independent of source capacitances up to 10 µF.
