FEMTO's HCA current amplifier provides precise offset voltage and bias voltage control through two trimming potentiometers. Wide-range adjustable input offset current compensation maintains full dynamic range even in signals with significant DC components. The bias output voltage can be precisely adjusted between -12 and +12 volts using a multi-turn bias trim potentiometer. Applications: Fast detection using large-area photodiodes; Spectroscopy; Photodetection using PMT and photodiodes; Ionization detectors; Pyroelectric and piezoelectric detectors
