The DLPCA-200 variable gain current amplifier proves to be a good choice for many research applications; as a result the DLPCA-200 is one of the most popular off-the-shelf amplifiers offered by FEMTO. The DLPCA-200 can be switched from 1 x 103 to 1 x 1011 V/A, and so is suitable for detection of signals from between sub-pico amps to milli amps range. The bandwidth of the device is DC to 500 kHz, making phase amplification possible by connecting in series with a lock-in amplifier.
Other features of the DLPCA-200 include:
switchable bandwidth for DC measurements, adjustable bias voltage, adjustable offset, switchable AC/DC coupling and remote / manual interface.
