Low-noise transimpedance amplifier
■ Input noise: minimum 0.2 fA/√Hz * Peak-to-peak: 0.4 fA ■ Gain can be manually or remotely changed from 10^4 to 10^13 V/A ■ Covers a wide dynamic range of over 240 dB, capable of handling current values from sub-fA to mA ■ Compact housing allows for installation near the signal source, reducing noise from long cabling ■ Various built-in filters optimize the amplifier's bandwidth according to the signal state, allowing for settings of S/N ratio and measurement speed based on the application ■ Even when the gain is set to maximum, it maintains sufficient measurement speed to measure femtoampere currents in real-time ■ At femtoampere levels, measurement errors and baseline shifts due to drift and offset currents are more likely to occur, but the DDPCA-300 excels in long-term stability, minimizing drift to an extreme degree.
