The DHPCA-100 is a variable-gain high-speed current amplifier designed for applications requiring the conversion of small electrical currents into voltages with a transimpedance gain ranging from 10¬= to 10,Å? V/A. It features a bandwidth capability from DC up to 200 MHz, with switchable upper cut-off frequencies of 1 MHz, 10 MHz, or full bandwidth, allowing for flexibility in signal processing. The amplifier supports both AC and DC coupling and includes an adjustable bias voltage for compatibility with external photodetectors. Input protection is provided against ¬±1.5 kV transients, ensuring reliability in demanding environments. The device can be controlled locally or remotely, making it suitable for various applications such as photodiode and photomultiplier amplification, spectroscopy, beam monitoring in particle accelerators, and as a preamplifier for A/D converters and high-frequency lock-ins. The amplifier's performance is characterized by low noise levels, with an equivalent input noise voltage of approximately 2.8 nV/,àöHz and a rise/fall time as low as 1.8 ns, depending on the gain setting.
The DHPCA-100 variable gain high speed transimpedance current amplifier is the perfect choice for applications that require the conversion of small electrical currents into usable voltages at bandwidths up to 200 MHz. It is ideally suited for DC- and AC measurements up to 200 MHz, time resolved measurements down to the ns-region and as the preamplifier for fast photodetector signals.
