Overcurrent monitor operates up to 26V

Using a current-sense amplifier, a high-side MOSFET driver, and a latching voltage monitor a circuit can be easily constructed that protects from overcurrent conditions and operates at voltages as high as 26V.

Create an audio preamplifier with an attenuator using the DS1802 push-button digital potentiometer

This application note discusses how to best bias the AC signal to within the DC supply range and how to use digital potentiometers in circuits designed for mechanical potentiometers. This understanding is crucial to effectively using the DS1802 in a pushbutton-controlled audio preamplifier circuit.

Extending high-side current detector operating voltage to 1kV using optocouplers

This application note describes the use of a current-sense amplifier along with an optocoupler to extend the operating voltage range up to 1,000 volts for high-voltage applications. The circuit relies on the optocoupler's isolation barrier to separate the high-side and grounded side of the 1,000V system. Op amps are used to eliminate photodiode non-linearity and drift and provide an accurate output voltage proportional to the load on the 1kV supply.
