SR556 — Current preamplifier Lock-In Preamplifier

PublishTime：2024-10-17

■The SR556 is a low-noise, high-bandwidth, fixed-gain current (trans-impedance) amplifier designed to work with SRS lock-in 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. Power is brought from the lock-in by a 9-pin cable. The SR556 can also be operated independently by applying the appropriate DC power.
●1 V/nA fixed gain
●5 fA/√Hz input noise
●Bias voltage input
●Powered by SRS lock-in amplifiers
