This reference design provides design ideas for a cost-effective, low-power liquid-level measurement data acquisition system (DAS) using a compensated silicon pressure sensor and a high-precision delta-sigma ADC. This document discusses how to select the compensated silicon pressure sensor, suggest system algorithms, and provide noise analyses. It also describes calibration ideas to improve system performance while also reducing complexity and cost.
NXPThe SABER platform enables you to evaluate the multimedia performance of ARM® Cortex®-A9-based i.MX 6 series processors.
Many industrial and medical applications require temperature measurements with accuracies of ±1°C or better, performed with reasonable cost over a wide range of temperatures (-270°C to +1750°C) and often with low power consumption. This article describes design of the cost-efficient, portable, high-resolution data-acquisition systems (DAS) based on precision delta-sigma analog-to-digital converters (ADCs). It also presents formulas and software for implementation of standardized linearization calculation algorithms to accurately cover this wide temperature range while ensuring reproducible measurements.
Development tools for the PXR40 32-bit Power Architecture microcontroller
This reference design demonstrates the use of the MAX98400 Class D audio amplifier in a stereo audio docking station application. The MAX98400 2.1 demo box is a complete powered speaker dock that uses two MAX98400 ICs to drive a 3-channel speaker system consisting of two 2in satellite speakers and one 5in subwoofer. The reference design is intended to be used with a portable audio player as its main music source. The overall solution size is very compact and features active equalization, power-supply monitoring, and dynamic equalization for the subwoofer.
This application note is a reference design for a PC-based temperature measurement system. It uses the MAX1396 and MAX6603EVKITs, a MAXQ2000 microcontroller, and MAX6603 signal conditioner. The design presents an easy way to obtain the temperature readings from the MAX6603 without requiring complicated conversion formulas. Schematics, block diagrams, and software are all provided.
Study kit for 16 HCS12 students
Nuvoton has designed many highly integrated single-chip solutions that can be used as integrated parts for future automobiles. Although the cost of ISD15D00 / ISD15C00 is low, it is the best audio quality recording and playback device in its class, allowing everyday low-end cars to have audio-level sounds or voice prompts. By providing smooth communication to the SPI port of the automotive network system, system integration becomes extremely simple. ISD15D00 uses external SPI flash memory audio with built-in regulator PWM speaker driver, analog digital input and output, suitable for multi-language storage devices and audio playback of up to 64 minutes. The ISD15D00 voice macro is designed for situations where, for example, the language of the external flash memory changes but the application software does not.
The MAXREFDES72# reference design is a software configurable interface adapter that allows Pmod boards to be connected to Arduino headers. This board addresses the level shifting and pin multiplexing challenges associated with adapting these different interfaces.
Storage oscilloscope, fully functional and verified, for graduation project
"Electronic dog" is a vehicle-mounted device, also known as "safety warning device". Its function is to remind the car owner in advance of the existence of electronic eyes or speed radar. It allows drivers to increase their driving attention in advance where there are safety hazards, and also prevents drivers from speeding or speeding. Fines and points will be deducted for violations.
