Ultimate High-Speed Current Amplifier DHPCA-100

The DHPCA-100 variable gain high-speed transimpedance current amplifier is an ideal choice for applications requiring the conversion of small currents into usable voltage (with bandwidth up to 200 MHz). It is well-suited for DC and AC measurements up to 200 MHz, time-resolved measurements down to the nanosecond range, and as a preamplifier for fast photodetector signals.
