Data Acquisition - Analog to Digital Converters (ADC)

The THC7984-17 is an 8-channel analog to digital converter (ADC) with a voltage input range of ±5V, which can convert an analog signal into a digital representation using its built-in low-noise 8-bit A/D converter circuit. This converter can work in a range of -40°C to +85°C.

Application Field

The THC7984-17 is designed for applications that require high accuracy, high speed and low power consumption, such as industrial automation, medical test and measurement, data acquisition, etc. It can be used in a variety of systems, such as process control, data logging, robotics, security systems, and more.

The THC7984-17 features high-speed A/D conversion, with conversion rates up to 9kHz without any external components. Also, the device includes a built-in temperature sensor to detect changes in temperature, as well as an interrupt/DMA request feature, allowing the ADC to trigger an interrupt whenever it detects a change in the voltage level.

The ADC supports a variety of input formats, allowing it to sample signals from a wide range of devices, including thermocouples, strain gauges, ultra-high-speed motors, and active filters. It can even be used to sense certain types of small signals, such as temperature level or time-dependent changes.

Working Principle

The working principle of the THC7984-17 is based on the Analog to Digital Conversion (ADC). An ADC processes an analog signal, usually voltage, and converts it into a corresponding digital signal. The first stage involves the analog-to-digital converter, which measures the voltage level and convert it into an 8-bit binary value.

The second stage is the conversion from binary to decimal. The analog signal is sampled at a given rate, and the digital signal generated is then converted back to its corresponding voltage level. This voltage level is then used to update the digital output of the ADC. The output voltage value is typically referred to as the digital output.

The THC7984-17 is then able to detect changes in the environment, such as temperature, and send back a corresponding, digital output, representing the change. The digital output can then be used to control or monitor a device or system, or provide useful data for further analysis.

Overall, the THC7984-17 is an 8-channel ADC designed for industrial, medical, and other applications requiring high accuracy, speed and low power consumption. It can be used to measure and convert signals from a variety of devices, and can be used to detect changes in the environment and generate corresponding digital outputs, making it a versatile and convenient tool for a variety of applications.
