BoostXL-ADS7142 Application Field and Working Principle

Expansion boards, daughter cards, and related accessories are increasingly used in tactical and environmental applications as the need for a custom design grows. The use of expansion boards, daughter cards, and related hardware add flexibility to the design process and allow designers to customize their designs for specific applications. The BoostXL-ADS7142 analog-to-digital converter (ADC) evaluation kit is a powerful example of this type of expansion board. The ADS7142 is a 24-bit ADC evaluation module designed to provide scalability and flexibility to an engineer or developer looking to explore mixed-signal architectures. By combining the ADS7142 with an integrated development environment (IDE), any user can develop their own custom application-specific solutions for analog data conversion.The ADS7142 evaluation board features a multiplexed input architecture, which allows the board to sample multiple inputs simultaneously or in succession. This multiplexing capability allows the kit to be integrated with various analog sources, such as thermocouples, flow sensors, accelerometers, and other mixed-signal components. It is important to note that while the ADS7142 has a sample rate of 200ksps, the sample rate can be adjusted with a simple programming change in firmware. When used in tandem with the BoostXL-ADS7142, the ADS7142 can be utilized in various application fields such as industrial automation, automotive, aerospace telemetry, medical equipment, and various other real-time applications. This flexible and low-power ADC board also serves as an ideal choice when interfacing with analog-to-digital converters or microprocessors.The ADS7142 evaluation board also features an integrated signal chain including a multiplexer, amplifier, Programmable Gain Amplifier (PGA), and a continuous time low-pass filter (CTLPF). This unique combination of signal conditioning components helps reduce the complexity of developing a mixed-signal circuit. It should also be noted that the board is capable of tolerating up to +/-15 volts applied to the board.The ADS7142 board also offers a digital interface, allowing developers to access the board’s configuration settings, data acquisition, bypassing the internal signal chain, and chain together boards for larger data acquisition applications. The interface is available through SPI, I2C, and USB. The board also has an onboard jumper which allows the user to easily switch between the three data transfer techniques.In conclusion, the BoostXL-ADS7142 ADC evaluation board is a superior and expansive resource for designers looking to integrate a mixed-signal circuit. The board combines the integrated signal chain, mixed-signal inputs, and versatile digital interface to offer the perfect platform for application-specific solutions. This powerful and easy-to-use resource is an ideal choice for application fields such as industrial automation, automotive, aerospace telemetry, medical equipment, and various other real-time applications.
