Data acquisition is an important field in modern electrical engineering and instrumentation. It plays a major role in data communication, analysis, and processing. In the field of data acquisition, analog to digital converters (ADC) are an essential technology. The AD7923SRU-EP-RL7 is an example of an ADC which can be used for various applications. This paper will discuss the application field and working principle of the AD7923SRU-EP-RL7.

The AD7923SRU-EP-RL7 is an 8-channel, 24-bit, low-power, single-channel ADC designed for weigh bridges and load cells. The device features a wide range of input voltages and low-noise performance (better than 0.5LSB INL). It is capable of sampling rates up to 5 MHz and offers high linearity accuracy. The device has an integrated reference voltage that allows it to handle a wide range of input signals. The AD7923SRU-EP-RL7 is suitable for industrial and medical applications such as patient monitoring, calibration, weighing, and other precision measurement systems that require highly accurate data.

The AD7923SRU-EP-RL7 uses a high-speed Delta-Sigma pipeline to convert analog input signals into digital values. The Delta-Sigma ADC architecture consists of three major stages: an input stage, a modulation stage, and a decimation stage. In the input stage, the analog input signal is buffered and amplified before it is passed to the modulation stage. In the modulation stage, the signal is converted into a stream of pulses or a pulse-width-modulated signal in order to approximate the analog input. Finally, the signal is sent to the decimation stage where it is reconstructed and then converted into a digital word. The AD7923SRU-EP-RL7 uses a multi-level, multi-bit architecture for improved linearity and dynamic range.

The AD7923SRU-EP-RL7 has an internal voltage reference that sets the full-scale input voltage range. The device also has a built-in temperature sensor which allows the internal reference voltage to be compensated for environmental changes. The device contains a low-noise amplifier and programmable gain amplifier that can be used to enhance input signal range. Additionally, the device is capable of rejecting frequency components up to 10 kHz. The AD7923SRU-EP-RL7 is designed to operate over a wide temperature range and can be easily configured using an I2C interface.

In summary, the AD7923SRU-EP-RL7 is an 8-channel, 24-bit ADC with low-noise performance and high linearity accuracy designed for weigh bridges and load cells. The device features an integrated voltage reference and temperature sensor for improved accuracy, as well as a low-noise amplifier and programmable gain amplifier for enhanced signal range. With its multi-level, multi-bit architecture, the device is capable of rejecting frequency components up to 10 kHz. The AD7923SRU-EP-RL7 has a wide temperature range and can be easily configured using an I2C interface.
