CS580 Current Source

· RS-232 and optical fiber interfaces

The Model CS580 Voltage Controlled Current Source creates
a new capability for researchers needing ultra-low current
noise in a flexible, easy to use instrument. The CS580 is
a natural companion product for use with sensitive AC
instruments such as lock-in amplifiers, providing a straightforward method for generating precision low-noise currents
directly from an AC or DC control voltage. Current is
both sourced and sinked with adjustable compliance voltage
up to ±50 V, giving full “four-quadrant” performance. The
CS580 is a welcome addition to any research lab studying
semiconductors and transport phenomena, superconductivity,
and nanotechnology, to name just a few.

· Low thermal drift

Ultra-Low Noise Design

· Up to 150 kHz bandwidth

With up to ±50 V compliance voltage, the CS580 can source
and sink precision AC and DC currents from 100 fA to 100 mA.
The CS580’s ultra-low noise design takes advantage of the
best transistors, op-amps, and discrete components available
combined with careful high impedance board layout to
achieve the highest performance possible. The design even
features linear power supplies rather than switching power
supplies, so switching frequency interference can never be
a problem.

· Sources/sinks current from 100 fA
to 100 mA
· ±50 V compliance voltage
· 1 nA/V to 50 mA/V gain
· 5 W max power

An actively driven guard provides the greatest bandwidth
(up to 150 kHz) and lowest possible leakage current. There’s
also a buffered monitor output for high impedance voltage
measurements.
