An analog-to-digital converter (ADC) is a peripheral device that converts continuous signals from analog origin into digital signals. The ADC104S021CIMMX/NOPB is a high performance, versatile 16-bit A/D converter with a low power, zero latency serial interface. It has a serial interface that can be used for very simple configurations, as well as allowing for more complicated and detailed linking over different buses. This device offers excellent performance, flexibility and low power consumption, making it well suited for a wide range of applications.

The ADC104S021CIMMX/NOPB specifically offers 16-bit resolution, with a sampling rate of 2.0 MHz. The transceiver offers a Serial Peripheral Interface (SPI) or Quad SPI (QSPI), which supports all four SPI modes. It also supports a slave Single-Wire UART (SWUART) interface, which can be used for communications with a microcontroller.

The power supply voltage range is 2.375 V to 5.25 V, with a maximum current of 1 mA and typical current of 0.9 mA. The device is specified over the commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature range and approximately fully specified over the -40/+85 °C range. Additionally, the device is available in an industrial/extended temperature range version (-40/-85/+125 °C).

Application Field

The ADC104S021 is suitable for multiple applications with its high performance and low power features. It can be used in industrial machines such as calibration systems, metering systems, HVAC (Heating, Ventilation, and Air Conditioning) systems, appliances, and medical imaging equipment. It can also be used in industrial automation systems such as assembly lines, or robotic arms. It is also suitable for automotive applications, including sensors and displays. Additionally, the ADC104S021 can be used in instrumentation applications, such as pressure and temperature monitoring, or any other application that requires converting analog signals into digital format.

Working Principle

The ADC104S021 converts analog inputs into digital information. It comes with a 16-bit resolution and four SPI modes, which provides versatility in different applications. The device is equipped with a differential A/D converter with four input channels, and a voltage reference input. It has a low power serial interface that allows for fast data-shifting and low latency communications. It also offers flexibility to simply make connections to any digital communication bus.

The device is able to take samples from the differential inputs (A, B and Ref) and convert them into digital samples. The A/D converter works in an iterative manner, by repeatedly shifting in a sample, comparing it to the reference, and shifting in more data until the desired level of accuracy has been achieved. The data is then stored and processed accordingly.

The A/D converter is configured by setting up the sampling rate, input gains, reference source and so on. After configuration, the device is ready to start the conversion process. Upon completion, the digital data is transferred to other peripherals over SPI or SWUART.

In summary, the ADC104S021CIMMX/NOPB is a high performance, low power 16-bit analog-to-digital converter with a serial interface support. It offers a variety of applications in different fields, such as industrial automation, automotive, instrumentation and communications. It is also suitable for applications requiring high resolution and low latency communication, as it can perform data conversion and transmission quickly and accurately.
