Self-Powered High Side Current Sense

Jan 31st 2001
This circuit takes advantage of the microampere supply current and Rail-to-Rail input of the LT1494. The circuit is simple because the supply draw is essentially equal to the load current developed through RA. This supply current is simply passed through RB to form an output voltage that is appropriately amplified. ...

Micropower Integrating Current Sense

Jan 31st 2001
This circuit takes advantage of the microampere supply current and Rail-to-Rail input of the LT1494. Supply current is only 3uA during integration and 5uA at the end of integration. ...
