Data acquisition systems require alignment of analog capabilities and digital capabilities through special circuits known as analog-to-digital converters (ADCs). MAX12559ETK+D is one of the latest ADC integrated circuit (IC) solutions in the industry. With its accurate timing, fast conversion speeds, and robust protocols, this product offers an outstanding performance and precisely fulfills the demanding requirements of next-generation data acquisition systems.

Application Field

The MAX12559ETK+D is a precision, high-speed, low power ADC that is fully integrated for use with single-ended and differential signals. With 16-bit resolution and a conversion rate of up to 1.44MSPS (Million Samples Per Second), the MAX12559ETK+D occupies only 5 x 5mm and is ideal for large-scale commercial and industrial applications, such as automotive, aviation, consumer electronics, communications, medical, and industrial control. Additionally, it is suitable for applications that require simultaneous sampling and has the ability to accept multiple analog input ranges. It provides the high resolution analog-to-digital conversion required for applications ranging from high-definition video to environmental monitoring.

Working Principle

The MAX12559ETK+D gives superior performance with a combination of speed and accuracy. The highly integrated design reduces power consumption while providing enhanced filter functions, a high SNR (signal-to-noise ratio), and low clock jitter to enable reliable data conversion. The ADC is composed of two inputs and one output, with up to 1.44MSPS conversion rate and 16-bit resolution for superior performance.

The MAX12559ETK+D uses pipeline ADC with two-step successive approximation register (SAR) architecture. It integrates a sampling device, two comparators, two registers, and two input encoders for precision analog-to-digital conversion. The integrated architecture enables the converter to sample the input signal and convert it to digital codes with a very short latency. The MCU then uses its own control logic to process the digital data and generate the corresponding output.

The MAX12559ETK+D operates in either single-ended or differential input voltage mode. It also has a built-in selectable gain of up to +3.3 VDC to reduce the input range. Furthermore, the product features an adjustable clock jitter of up to ±2 nsec and an adjustable input clock rate of up to 850 MHz. This provides more flexibility in terms of sampling rate and accuracy.

The product also features built-in noise cancellation functions, such as common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) to eliminate interference from the surrounding environment and to ensure reliable data conversion. Furthermore, the MAX12559ETK+D has a selectable low-pass filter for suppressing high-frequency noise and artifacts.

In addition, it includes a simple Serial Peripheral Interface (SPI) to allow for low-overhead communication between the ADC and other devices in the system. The proprietary SPI protocol also ensures reliable data transmission and enables the user to change settings and make adjustments quickly and easily.

Conclusion

The MAX12559ETK+D ADC is an ideal solution for data acquisition applications that require high-speed and precise analog-to-digital conversion. Its highly integrated design greatly reduces power consumption and provides superior performance. Additionally, the product features adjustable clock jitter and an adjustable input clock rate to achieve more flexibility. Finally, its built-in selectable gain, noise cancellation features, and SPI interface make it an excellent choice for commercial and industrial applications that require high-speed, reliable data conversion.
