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.

High performance 1-Wire network driver

This document describes a microcontroller-based 1-Wire® master interface for reliable operation of small, medium, and large 1-Wire networks. This is accomplished using careful impedance matching, intelligent (software-controlled) active pullup, and slew-rate control. Software flow charts are included to assist the user in generating the correct 1-Wire timing for reset pulse, presence detect, write one, write zero, and read time slots using any suitable microcontroller. Scope traces illustrate the timing performance of the driver as well as transmission line effects as they appear with long cables.
