by Crutschow, Electro-Tech-Online community member A Wheatstone bridge is sometimes used to convert a variable resistance, such as a thermistor or strain-gage, to a voltage with zero volts out at some particular resistance (such as at 0°C for the thermistor). A bridge circuit has the advantage of being able to generate a 0V null output […]

MEMS inertial accelerometer now offered in ±10 g and ±50 g ranges
Silicon Designs, Inc. announced that additional new g-ranges and end-user enhancements have been added to its Model 2227 MEMS inertial accelerometer series. Initially launched in October 2018 as a strictly ±25-g product, the Series is now offered in both ±10 g and ±50 g ranges, respectively. Stock quantities of all three models are immediately available […]
Choosing the right MEMS microphone interface for your project
Micro-electro-mechanical systems (MEMS) microphones have been steadily increasing their market share, driven by the surge in popularity of voice-controlled electronics with applications like voice-enabled navigation devices and digital home assistants. But what are the different types of MEMS microphone electrical interfaces available and how do you apply them to your application? A MEMS microphone with […]

Filters, Part 2: SAW and BAW devices for RF
Part 1 of this FAQ looked at the basic available electronic filters – analog, switched capacitor, and digital – and briefly reviewed the attributes of each. As the frequencies to be filtered reach to 1 GHz and well beyond, while the selectively needed also became narrower, these filter approaches can no longer support many of […]
Isolated analog amps provide accurate current measurements
Silicon Labs has introduced a family of isolated analog amplifiers, voltage sensors and delta-sigma modulator (DSM) devices designed to provide accurate current and voltage measurement with very low drift across temperature. Based on Silicon Labs’ robust, third-generation isolation technology, the new Si89xx family provides flexible voltage, current, output and package options to help developers reduce BOM […]
