As the various components used in different electronic applications require a broad range of compatibility and efficient performance, the requirement of engineering evaluation boards has been mushrooming recently. EVAL-AD7944FMCZ, a high-performance evaluation board from Analog Devices is one such board that is especially designed for measuring signals right from the source for a sophisticated hardware and software design. It can be best classified as an Evaluation Boards – Analog to Digital Converter (ADCs).

EVAL-AD7944FMCZ comprises an analog front end (which includes an adjustable current source, a differential amplifier and a low noise amplifier) for responsive input to the ADC and outputs the digital data. The board can sample signals right from 0nA to 24mA with a guaranteed measurement resolution of 24-bit, sampling at a rate of 16MS/s. Moreover, it can also measure Voltage, Temperature (RTD and thermistor) and Strain (bridge-based measurements) with ease.

The board is perfect for fast development and testing of critical system and control applications that require the required information in a short span of time. The availability of numerous analog and digital communication ports make it suitable for both centralized and decentralized testing. Moreover, the ability to validate the board’s performance using Analog Devices’ SDK makes EVAL-AD7944FMCZ stand out from the rest of the analog-to-digital converter boards available in the market.

To understand the working principle of the EVAL-AD7944FMCZ, it is necessary to comprehend its components. The AD7944 is an efficient analog-to-digital converter that is compatible with 16-bit single-ended input signals. It features a 24-bit measurement resolution and ensures that the entire signal range is accurately converted into digital form. The Analog Devices’ toolbox makes it possible to configure the board for a wide range of applications. The AD5941 is the 12-bit sigma-delta analog-to-digital converter used in this board and is designed to be used in power metering applications. The board also features a precision n-bit DAC (Digital-to-Analog converter), nonvolatile memory, voltage and current regulators, flash memory, and a serial port to interface with other external devices.

One of the most unique aspects of EVAL-AD7944FMCZ is its ability to measure different types of inputs. It can measure current input with a precision of 0nA to 24mA and voltage input of 0-5 Volts with a maximum resolution of 64nV.
