Current Amplifiers
The wide variety of amplifiers are created for different types of solution to ensure high performance is achieved in every experiment. The amplifiers’ bandwidth and frequency response are independent of source capacitance.
Amplifiers do not require unique adaptation or frequency compensations; gain stays constant & nicely flat at different high source capacitance. The current amplifiers come with a wide variation of Bandwidths, noise currents, transimpedance & many other adjustable components.
Custom-designed modules are also available to provide the most holistic solution to your needs. Please contact us for more details.

Sub Femto Ampere Sensitivity Variable Gain DDPCA
The DDPCA is the low noise transimpedance amplifier that covers an extensive dynamic range of more than 240 dB for the measurement of currents from sub Femto amps up to milliamps by merely switching the gain range.
The DDPCA has a vast gain range (10^4 up to 10^13 V/A ) that can be set either manually or using a remote interface. |
FEATURES
Input noise values down to 0.2 fA/√Hz 0.4 fA peak-to-peak noise Integrated with various filters; to adapt the bandwidth to the varying signals Real-time current measurements Wide Range Gain; Transimpedance gain: 10^4-10^13 V/A 240 dB dynamic range for sub-fA to mA measurements Adjustable voltage on input for DUT biasing |
Ultra Low Noise Fixed Gain LCA
The ultra low noise performance is achieved by selecting at very high gains, all while maintaining the associated bandwidth reduction.
The amplifiers also do not require unique adaptation or frequency compensations; bandwidth and frequency response are independent of source capacitance up to 10 nF. No gain peaking will occur. |
FEATURES
Input noise down to 180 aA/√Hz Bandwidth up to 400 kHz Gain up to 10^13 V/A Flat frequency response EMI-shielded case |
High Speed Fixed Gain HCA
The HCA provides the extremely clean and high-quality current output with high-frequency components; no gain peaking, oscillation or significant bandwidth reduction will occur, even for source capacitances up to maximum 2 nF.
No frequency compensation or special adaptation is needed, and the bandwidth & gain remains constant even at very high specified source capacitances. |
FEATURES
Minimum input noise 270 fA/√Hz Bandwidth up to 400 MHz Gain up to 10^6 V/A Flat frequency response Stabilized and adjustable bias voltage output for biasing external photodiodes EMI-shielded case |
Low Noise Variable Gain DLPCA-200
The DLPCA is an all-rounder transimpedance amplifier; designed for applications that require the conversion of small currents into usable voltages.
|
FEATURES
