Working Principle of THS1401EVM

The THS1401EVM works on the principle of conversion of analog signals to digital signals. It consists of the THS1401 ADC and the MCU. The ADC is a low-power, 12-bit, 1.2 MSPS analog-to-digital converter with analog input ranges from 0 V to 2.5 V, multiple data streaming applications, and high-speed multiplexing. The MCU consists of an embedded ARM Cortex-M4 processor. The ADC and the MCU are connected via SPI and provide data streaming capabilities to the system with low latency.

The ADC module converts the input analog signal into a 12-bit digital signal. The MCU reads the digital signal and performs digital signal processing to control the ADC. The MCU and ADC are connected via SPI. The MCU issues commands to the ADC and the ADC responds with data. The ADC supports four data streaming modes: time-stamped sample mode, dual-channel data streaming mode, multiplexing data stream mode, and rapid continuous data streaming mode. The MCU controls and configures the ADC for each of the data streaming modes. The ADC and MCU are connected via a four-wire interface that allows data to be streamed from the ADC to the MCU at high speed with low latency.

The MCU also provides tools for debugging the THS1401EVM evaluation board. It includes a GUI for programming and controlling the ADC and a code development environment to write programs to control the ADC. The MCU also provides features such as hardware monitoring, data filtering, and signal processing algorithms. The ADC also supports calibration and measurement functions which can be used to enhance the performance of the ADC.
