Analog to Digital Converters, or ADCs, are electronic circuitry used for converting data from analog form to digital form. In particular, they act as a bridge between the analog world and digital world, providing a convenient way to control, transfer, store, retrieve, and process data. The ADS1015EVM Evaluation Board is designed as an evaluation, demonstration, and development platform for the ADS1015 12-bit analog to digital converter (ADC) from Texas Instruments Incorporated (TI). This application and working principle paper explains in detail the key advantages and features of the ADS1015EVM board, as well as the principles of analog to digital converter (ADC) and applications of the board.

Overview of Analog to Digital Converters (ADCs)

Analog-to-Digital Converters (or ADCs) are electronic devices used for converting data from analog form to digital form. ADCs typically measure an analog signal and convert it into digital values, usually in binary form for computer processing. An Analog to Digital Converter measures the voltage of the analog input signal and converts the measured analog signal into a digital-equivalent value via a series of discrete steps or "levels". The process works by measuring the degree of change from a known reference voltage. The ADC then re-samples or quantizes the analog input over a fixed number of steps to produce a digital equivalent.

ADC’s are used in a variety of industries and applications, including medical imaging and monitoring, audio/video, telecoms, and power management. In addition, ADCs are important components in embedded systems—small, stand-alone systems with processing, communication, signaling, and control capabilities.

ADS1015EVM Application Field and Working Principle

The ADS1015EVM Evaluation Board is designed as an evaluation, demonstration, and development platform for the ADS1015 12-bit analog to digital converter (ADC) from Texas Instruments Incorporated (TI). This board provides a convenient and easy way to evaluate the ADS1015’s features and performance. The board can be used both in the lab and in-field. It can also be used as the basis for creating custom applications.

The ADS1015EVM features two onboard jumper connectors, enabling power supplies of either 5V or 3.3V to be used with the board. The ADS1015EVM board is designed with an input voltage range of 0V to 3.3V. It has 4 input channels each with an input impedance of 30Kohms, as well as 4 digital output channels. It also features an onboard LED which flashes orange when within range of the ADC, and red when not.

The ADS1015EVM is designed for users to understand how the ADS1015 ADC works. The board allows the user to select the input voltage with a jumper, set different sampling intervals, monitor the ADC’s output via a red and orange LEDs, and access the digital output data via a USB or Ethernet connection. The board can also be used as a reference design for designing custom applications. Furthermore, the board is extremely low-power, allowing it to be used in battery-powered systems.

The ADS1015EVM board supports most of the features available on the TI ADS1015 ADC. The onboard microprocessor also provides simple commands such as Voltage Setting and is capable of controlling other features such as offset, gain, or temperature measurement. The device can also be used to measure frequency and duty cycle of signals.

The ADS1015EVM is a versatile and powerful tool for evaluating and developing applications with the ADS1015 12-bit ADC from TI. It can be used to perform one-time measurements or continuous monitoring of analog signals, and can be used both in the lab and in the field. The board also provides users with a low-power, easy-to-use platform for developing custom applications.
