Introduction

The EVAL-AD7793EBZ is an evaluation board for an analog-to-digital converter (ADC) from Analog Devices. This evaluation board can be used to accurately measure, digitize, and convert analog signals into digital signals. This board integrates a new high-performance dual-channel, low-power, 16-bit Sigma-Delta AD7793 ADC. It also incorporates an internal voltage reference, a serial control interface, and a temperature sensor. The board is based on the AD7793 chip, which is an integrated, single-supply, dual-channel, sigma-delta AD converter. This solution is suitable for low frequency signal conditioning and medium frequency measurements up to 300 kHz.Features

The EVAL-AD7793EBZ board has several features that make it the ideal solution for measuring and digitizing low frequency and medium frequency analog signals. The board includes an internal voltage reference, a serial control interface, and a temperature sensor. The onboard voltage reference provides the required accuracy and stability for signal conditions and measurements. The board is also equipped with a 3-wire SPI interface, which allows for easy and straightforward control and data transmission. The board also features a temperature sensor, which provides temperature measurement with a resolution of 0.5ºC.Applications

The EVAL-AD7793EBZ board is designed to be used for several applications. The board is suitable for use in precision voltage measurements and analysis, as well as accurate accelerometer readings. The integrated temperature sensor can be used to control industrial process plant temperatures or environmental temperature monitoring. The ADC can also be used in conversion rate monitoring and battery monitoring systems. In addition, the board can be used in applications such as medical instrumentation, automotive electronics, and industrial process control systems.Working Principle

The EVAL-AD7793EBZ board is based on the AD7793 chip, which is an integrated, single-supply, dual-channel, sigma-delta AD converter. The AD7793 chip is a dual-channel ADC, which means it can process two analog signals simultaneously. The EVAL-AD7793EBZ board also includes an onboard voltage reference, a serial control interface, and a temperature sensor. The onboard voltage reference provides precise 1.25V, 2.56V, and 4.096V references for the ADC measurements. The reference signals are connected to the ADC’s positive input (Ain+). The ADC measures the difference between the reference signal and the analog signal applied to the negative input (Ain-). The ADC then converts the difference into a 16-bit digital signal, which can be read out using the board’s SPI interface. The onboard temperature sensor can provide temperature measurements with a resolution of 0.5 ºC. The temperature sensor is connected to the ADC’s Temperature Input (Tin). The ADC then converts the temperature value to a 2-bit digital signal, which can be read out via the board’s SPI interface. Conclusion

The EVAL-AD7793EBZ evaluation board is an effective tool for accurately measuring, digitizing, and converting analog signals into digital signals. The integrated voltage reference, serial control interface, and temperature sensor make the board ideal for low frequency and medium frequency measurements up to 300kHz. Additionally, the board can be used for a wide variety of applications, ranging from medical instrumentation to industrial process control systems.
