Evaluation boards are used to demonstrate the full capabilities of the device, and the ADS62C15EVM is no exception. With a resolution of up to 14-bits, this board is ideal for applications requiring wide dynamic range, integration time, and low-distortion performance. Furthermore, the evaluation board is also built around the low-power ADS62C15, which is an ultra-compact, high-speed, low-noise, low-power analog-to-digital converter (ADC).

ADS62C15EVM Application Field

The ADS62C15EVM is a versatile evaluation board for the ADS62C15 ADC, and is capable of being used for a wide variety of applications. This board can be used for signal acquisition, instrumentation, communications, data acquisition, military, industrial and medical test systems.

For basic signal acquisition and instrumentation, the ADS62C15EVM board is an ideal choice. The board can be used to accurately capture the amplitude, phase, or noise characteristics of signals with excellent linearity and low distortion levels. The onboard precision clock and on-chip pulse width modulator (PWM) can be used for synchronous sampling and random sampling applications as well.

The board also offers support for both frequency- and amplitude-agile communication systems such as sigma–delta modulators, GMSK modulators, and multi-carrier modulators. It is also suitable for frequency control applications since the on-chip PWM has a configurable duty cycle versus frequency converter that enables fine tuning of the output frequency.

For data acquisition systems, the board can be used for both wide- and narrow-band signals with multi-channel acquisition. The built-in multi-ADC synchronization support helps to reduce the need of off-chip timing components. Moreover, the board also has a delay adjust control that allows for multiphase sampling, which is essential for high-speed data acquisition systems.

The ADS62C15EVM can also be used in military systems whenever very low power consumption and tight timing requirements are necessary. In addition, for medical test systems, the high resolution, fast throughput and low noise are also important features that can be provided by the board. For industrial control and electronic equipment such as pulse-width-modulated servo systems, the board can provide low-noise sine waves with adjustable integral time constant.

ADS62C15EVM Working Principle

The ADS62C15EVM board is based on a low-power, 14-bit ADC—the ADS62C15—which performs conversions at a sampling rate up to 8.192 MSPS. This ADC features fully differential inputs, adjustable gain, adjustable input offset, sample/hold, delay adjust control, and multi-ADC synchronization support.

The board includes a precision clock that helps to ensure low-jitter, linearity, and distortion with selectable sample rates from 125 ksps up to 8.192 MSPS. The clock generator operates at temperatures ranging from -40°C to +85°C, allowing for reliable operation across a wide range of temperatures.

The board can also be used with a variety of software, such as the graphical user interface (GUI) application, which helps users to quickly and easily configure and test the board. The GUI features an oscilloscope view, frequency range filtering, and signal and noise visualizers.

The user can also use the Python interface to facilitate direct and easy access of all parameters and settings, together with programmable register settings used for advanced control. This helps to reduce the time and effort it takes to get the system up and running.

Finally, the ADS62C15 also features on-chip digital signal processing (DSP) capability, which can be used to acquire frequency-dependent information from signals. This makes the board ideal for smart sensors, data acquisition systems, and motor control applications.

Conclusion

The ADS62C15EVM evaluation board provides an easy-to-use solution for those looking to take advantage of the features offered by the ADS62C15 ultra-compact ADC. It is versatile and can be used in a wide range of applications, from basic signal acquisition and instrumentation to advanced communication and data acquisition systems. The board provides excellent resolution, noise performance, and wide dynamic range, and has integrated software support that helps to reduce development time.
