Low level VI converter: 0V-5V input to 0uA-5uA output

X3G022579FC1H-V
1.5PF SOT23-6 Low Capacitance 5V Breakdown Voltage 6V SRV05
MCP604-I/SL

description

This verification design is a microampere voltage-to-current (VI) converter circuit that provides accurate low-level current to the load. This design operates from a single 5V supply and uses high precision low drift op amps and instrumentation amplifiers. The scope and accuracy of the VI converter can be changed with a simple modification.

Separate Slip Ring

A separate slip ring is a device that allows two or more rotating electrical shafts to be connected without having to pass the electricity through the shafts' bearings. This is often used in situations where there is a need to power something externally while the shaft is still turning. For example, a machine might have a drive shaft that powers it while also having a separate output shaft that needs to turn at a different speed. By using a separate slip ring, these two shafts can be powered without any interference.


Slip Ring Shaf is a key component of a slip ring. It is the shaft on which the rotary electrical contacts are mounted. The shafts must be strong enough to support the weight of the contacts and must be able to turn freely. There are many factors to consider when selecting a shaft material, including strength, corrosion resistance, and operating temperature.
