ADS7812PB Application Field and Working PrincipleData Acquisition - Analog to Digital Converters (ADC) are one of the most common components of modern communication systems, because of their versatile abilities to convert analog signals into digital signals. The ADS7812PB is a low cost and high performance ADC specifically designed for use in data acquisition and communication systems.The ADS7812PB is a 12-bit A/D converter with low power consumption, high accuracy, and excellent linearity. It supports both single-ended and differential input ranges, and is well suited for applications with both high and low speed sample rates. The device is fabricated on a high performance BiCMOS process and packaged in an industry standard 16-pin SOIC package.The ADS7812PB utilizes a differential input stage. The conversion process starts with a differential amplifier, which amplifies the difference between the two inputs. The amplifier then drives an input sample-and-hold circuit, which captures the differential voltage at a certain point in time. This sample-and-hold output is then sent to a low-noise current switch, which switches the two input signals onto two separate summers.The summers integrate over an interval of time, and the sum of the two integrals is sent to the comparator, where it is compared with a reference voltage. The comparator then sends the result to the next stage of the conversion process, which is the flash conversion stage. The flash conversion stage is a high-speed binary search algorithm which looks for the point in the input range where the input voltage and reference voltage are nearly equal. This is the point at which the A/D conversion is complete.The output of the ADS7812PB is word-width synchronous, meaning that the A/D output is set at the same time as the Digital-to-Analog Converter (DAC) output. The output is 12-bits wide, and supports both single-ended and differential output ranges depending on the application. The device supports a wide range of sampling rates, from DC to 250 Khz.In summary, the ADS7812PB is a low cost and high performance ADC specifically designed for use in data acquisition and communication systems. With its low power consumption, high accuracy, and excellent linearity, it is well suited for applications with a range of sampling rates. Its 12-bit resolution, differential and single-ended input ranges, and wide variety of output ranges make it a versatile device for a range of applications.
