Ratiometricity is a common approach for measuring analog-sensor signals for the purpose of conditioning and standardizing the signal for proper operation with an industrial control system. In the context of linear-variable differential-transformer (LVDT) signal conditioning, ratiometric measurement has a specific meaning. In this article, ratiometric measurement is described in general and also in the context of LVDT-sensor signal conditioning in three different stages of the signal chain.
The INA117 is a monolithic difference amplifier with the unique ability to accept up to ±200V common-mode input signals while operating on standard ±15V power supplies. Using on-chip hig
This document provides an overview of barometric pressure sensing, digital air pressure sensor and use cases.
The document is intended for Infineon customers who wish to develop applications based on DPS310 barometric pressure sensor.
Well-designed electronic systems only use as much power as they need to for each state of operation. While this is crucial for battery-powered systems, AC powered systems also benefit from minimizing power, since that reduces heat dissipation, maximizes the product lifetime, and conserves electricity.
Low-power modes work best when they seamlessly transition to a higher power mode without the user taking separate action. This full automation will be paramount to smart systems of the future. When the power mode can change based on some mechanical movement occurring, Hall effect sensors are often a suitable technology to be used.
Several features commonly used in microcontroller (MCU) designs, such as external EEPROMs, SHA-1 authenticators, temperature sensors, digital switches, and battery system monitors, use a single bidirectional line to transfer data between itself and a master device. Commonly referred to as 1-wire or SDQ single-wire serial interfaces, this communication peripheral reduces the number of physical hardware connections required while adhering to a protocol that can be easily achieved with MSP430 MCUs acting as the function's master. Commands can be basic enough to operate with the MSP430FR2000 MCU, which contains 512 bytes of main memory, or expanded to service a multitude of operations and slave devices. A code example that demonstrates the initialization of such an interface is below. To get started, download project files and a code example demonstrating this functionality.
The 16-bit MSP430 and the 32-bit SimpleLink MSP432 microcontroller (MCU) families complement each other in low-power and performance. The goal of this migration guide is to help developers accurately assess the effort to migrate an existing application from the 16-bit MSP430 to the 32-bit SimpleLink MSP432 Arm platform if they so choose to. Ultimately, the migration guide is built to help derive a migration strategy with complete hardware and software coverage that properly migrates the existing application without introducing bugs due to platform differences while still taking advantage of the unique features or performance improvements that the 32-bit MSP432 devices bring.
