This application note describes how to use the LTM2881 to build a dedicated isolated 5V power supply with no external components, capable of delivering 1W of power.
New components have made 18-bit DACs a practical design alternative. This application note describes a measurement technique for 18-bit DAC settling time, which is the time required for the DAC output to settle to within 4ppm of the command code.
This application note describes Linear Technology’s 2-Wire Virtual Remote Sensing technology for voltage regulators. The technology eliminates the line-drop effect on the source output voltage and does not require additional sense wires.
This document describes the stable temperature performance of the LTC5582 and LTC5583 series RMS detectors, and how to improve measurement accuracy through temperature compensation. These RMS detectors maintain stable performance in a temperature range of -40°C to 85°C, at frequencies up to 10GHz (LTC5582) or 6GHz (LTC5583). By using two external resistors for temperature compensation, the measurement error can be reduced to less than 0.5dB.
