The DLPCA-200 is a high-end current amplifier optimized for DC measurements and time-resolved measurements down to microseconds.
- Ideal for a wide range of applications that require converting small currents into effective voltages, such as photodiodes and lock-in systems. - Adjustable bias voltage/offset. - The transimpedance gain is also variable, ranging from 10^3 to 10^11 V/A. - Promises maximum speed even at high gain settings. - The 3dB bandwidth at the maximum gain setting of 10^11 V/A is 1.2 kHz, with a rise time of 300 μs. - AC/DC is adjustable, and control methods can be selected from manual operation or opto-isolated remote control. - The case is a sturdy and compact EMI shielded enclosure that protects the product from noise and other interferences. - No frequency correction or special connections are required. - Comes with a removable 10 Hz low-pass filter to eliminate bandwidth noise. - Convenient for accurate and low-noise DC current measurements down to femtoamperes.
