Evaluation Boards - Analog to Digital Converters (ADCs)

The ADC141S626EB/NOPB, or "Analog to Digital Converter," is a powerful and flexible evaluation board designed for high speed data acquisition applications. This board provides 16-bit simultaneous sampling from up to 16 analog channels and is equipped with an integrated digital signal processor (DSP) to provide high speed signal processing and signal conditioning. The onboard DSP allows for adjustable sampling rates, digital filters, filtering strategies, and other digital signal processing features.

The ADC141S626EB/NOPB is based on the Texas Instruments ADC141S626EB chip which features sixteen 16-bit low-noise Programmable Gain Amplifiers (PGAs), sixteen 16-bit Analogue-to-Digital Converters (ADCs) and sixteen Digital-to-Analogue Converters (DACs). The PGA gain can be programmed in four different ranges up to 32 times. The PGAs can also be used as signal conditioning elements with filter and gain adjustment options. The ADC141S626EB chip is also capable of time resolution of one clock cycle, allowing for high speed measurements in each channel.

The evaluation board is designed to be used extensively in a wide range of applications including radar imaging, machine vision, telecommunications and medical imaging. It is equipped with an LCD display, which allows users to view real-time measurements and settings. Furthermore, it has a control arm with which users can access a range of features and functions such as dynamic adjustment of sampling rates and filters.

The ADC141S626EB/NOPB evaluation board\'s working principle is based on an open loop transimpedance amplifier. This amplifier receives an initial voltage from the input signal and amplifies it. The amplified voltage is then digitized and stored in the 16-bit Analogue-to-Digital Converters for further signal processing. The PGAs control the gain at the input stage of the transimpedance amplifier and provide adjustable filtering options for signal processing. Additionally, the onboard DSP is used to adjust sampling rates, trigger types, filters, and other parameters of the data acquisition board.

In summary, the ADC141S626EB/NOPB evaluation board is a powerful data acquisition tool, geared towards use in high speed applications. Featuring 16-bit simultaneous sampling from up to 16 analog channels and an integrated DSP for signal processing, this board is ideal for a variety of applications like telecommunications, medical imaging, and radar imaging. The open loop transimpedance amplifier at the heart of the board provides signal gain adjustment and filtering options, and the LCD display offers access to real-time measurements and settings.
