ADS8345N/1K Working Principle

The ADS8345N/1K ADC is a mixed-signal, 8-bit serial ADC, designed for use in data acquisition systems. It uses a single analog input to produce an 8-bit digital output. The ADC works by performing multiple conversions in a single cycle, which allows it to achieve high resolution with minimal power consumption. The actual conversion process starts with a differential input stage, which is made up of two independent comparators. The data is then converted to single-ended signals and the output is digitally smoothed.

Once the input is converted, the ADC begins to output a series of 8-bits to be read. Each bit is converted by comparing it to an offset voltage, which is changed according to the input voltage range. The output voltage is then converted back to a digital value and the conversion is complete. In total, the ADC takes 8 clock cycles to complete the conversion process. To further reduce power consumption, the analogue-to-digital converter (ADC) is able to enter into a sleep mode between each conversion.

The ADS8345N/1K ADC supports a wide range of voltage ranges, from 0 Volts to 5.2 Volt. It has a low operating temperature range, from -40 degrees Celsius to +85 degrees Celsius, making it suitable for a variety of applications. The ADC is also equipped with an adjustable voltage reference and programmable offset and gain registers, allowing for precise data acquisitions.

Conclusion

The ADS8345N/1K is an 8-bit serial analog-to-digital converter (ADC) that delivers high accuracy and low noise performance, making it suitable for a wide range of applications. Its low-power consumption and wide input voltage range make it an ideal choice for battery-powered devices and data acquisition systems. The ADC also has adjustable voltage references and programmable offset and gain settings, allowing for precise data acquisition.
