Overview
Multichannel Current Source is a programmable bipolar low-noise current source with 8 independent outputs.
Features:
- 8 independent ground-referenced channels
- Two ranges (±4 mA and ±40 mA) with 16-bit resolution (0.125 µA and 1.25 µA, respectively)
- Ability to combined channels in parallel to increase available current
- Ultra-low noise (10 pA/√Hz at 1 kHz)
- Stable with resistive and inductive loads
- Programmable outputs
