Variable Gain Current Amplifier Comparison

Model DLPCA-200 – The All-Rounder Variable gain from 10³ to 10¹¹ V/A Detection of sub-pA to 10 mA Bandwidth DC to 500 kHz Rise time down to 700 ns Low noise down to 4 fA/√Hz THE all-purpose current amplifier


	Model DHPCA-100 – For Higher Speed Bandwidth DC up to 200 MHz Rise time down to 1.8 ns Variable gain from 10² to 10⁸ V/A Built-in signal filters for reduced broadband noise


Model DDPCA-300 – For Highest Sensitivity Very low noise: min. 0.2 fA/√Hz Variable gain from 10⁴ to 10¹³ V/A > 240 dB dynamic range for sub-fA to mA measurements Very low drift < 1 fA Easy to use: convert your standard voltmeter to a high-end sub femto ampere meter
The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
