SR556 - Current Preamplifier

5 fA/√Hz input noise Powered by SRS lock-in amplifiers Powered by SRS lock-ins SR556 Current Preamplifier The SR556 is a low-noise, high-bandwidth , fixed-gain current (trans-impedance) amplifier designed to work with SRS lockin amplifiers. Current amplifiers provide gain close to the experimental detector, allowing the user to minimize input cable length and its corresponding input capacitance. The SR556 minimizes noise and pickup before they permanently degrade the signal-to-noise ratio, reducing measurement time in noise-limited experiments.

The SR556 minimizes noise and pickup before they permanently degrade the signal-to-noise ratio, reducing measurement time in noise-limited experiments. The SR556 can also be operated independently by applying the appropriate DC power.
