Data Acquisition - Analog to Digital Converters (ADC)The AD7896JRZ-REEL is an application field analog-to-digital converter (ADC) which is an important component for data acquisition systems. This device consists of differential analog inputs and Flash-based technology. Furthermore, it can convert an input of 2.7V to +/-10V single as well as multiple channels. It is designed for applications such as data logging, monitoring, and control.In order to understand its working principle, it is important to understand the three components: its transducer, amplifier, and ADC. A transducer is a device that converts one type of energy into another. It is most commonly used in sensing systems and instrumentation which measure electrical signals and convert them into usable signals. The amplifier is used to amplify the signal generated by the transducer until it is of a suitable size to be used as an input to the ADC. The ADC is then responsible for taking the input signal and converting it into digital data.The AD7896JRZ-REEL is a single-channel, 10-bit ADC. It has two differential analog inputs with a single-ended remote-sensing reference. The on-chip wide-range converter has a 12-bit output code with a settling time of 5µs for a 10-bit result. The wide temperature operating range allows the device to be used in a wide variety of applications.The AD7896JRZ-REEL contains an internal multiplexer which can select between the two input channels. The choice of input can be controlled through the multiplexer control lines. The on-chip reference and reference buffer provide excellent performance over a wide temperature range.The device is designed for low power operation and is rated for operation from power supplies ranging from 4V to 5.5V. The low-power mode allows the device to enter sleep mode to reduce power consumption. The device also has a standby mode that reduces power consumption while maintaining low latency.The AD7896JRZ-REEL works by taking the analog input signals and converting them into digital values. It contains an 8-bit digital-to-analog converter (DAC), which can be used to provide a reference voltage for the ADC to compare the input signal against. The transducer and amplifier stage prepares the input signals to be used as the ADC’s input voltage. The comparison between the input voltage and the DAC reference voltage is made internally by the device. The data that the ADC produces is available on the serial interface.The AD7896JRZ-REEL is a very useful device for data acquisition systems which require both single-channel and multiple-channel input capabilities. It is designed for low-power operation and provides excellent performance over a wide temperature range. Its transducer and amplifier stage as well as its reference and buffer circuits make it a reliable source of data for a variety of applications.
