A guide to using FETS for sensor applications, Part 2

In some JFET op amps such as the AD743, the input capacitance is in the order of 18 to 20 pF. In comparison, with an LSK489 dual FET, the input capacitance is in the order of 3 pF, which will be suitable for low noise photodiode applications. In this section we will see why it is important to have low equivalent input noise and low input capacitance in a photodiode preamp. A simple photodiode is shown in Fi ...

Si4707 Hookup Guide

Introduction Weather-band radio is an awesome public service provided in the US, Canada, and Bermuda. With hundreds of transmitting stations dotting the country, weather radio acts as the “voice of NOAA” (National Oceanic and Atmospheric Administration). In addition to spouting out weather forecasts, weather radio also implements a messaging protocol for emergency weather alerts called SAME (Specific Area M ...
