It is a useful tool for developers who want to use the BD14210G in their prototypes and applications. It is ideally used in industrial equipment and telecom equipment. 

BD14210G-EVK-001 Evaluation Board Features  

The BD14210G-EVK-001 Evaluation Board features a high-performance, low-noise current sense amplifier. It has a maximum current range of 100A and a typical noise level of 20µV. The board has a bandwidth of 1 MHz and a low noise figure of 0.3 nV/√Hz. The board gives accurate measurements of current, which can be important in applications where precise current measurement is critical. 

This evaluation board operates from a single power supply with a voltage ranging from 2.7V to 5.5V. It has a wide common-mode voltage range from -0.2V to +26V and provides analog voltage as an output. The matched gain resistor minimizes gain error and realizes low offset voltage. The input bias current is 1 μA at typical conditions. 

The board includes a regulated power supply that provides a stable power source for the BD14210G. The power supply has a nominal output voltage of 5 V and a maximum output current of 1 A. The regulated power supply guarantees a safe and consistent voltage output, which helps protect sensitive components from potential damage.

The evaluation board provides headers and connectors for power supply input, motor output, and external device interfaces for swift connectivity. This enables quick and straightforward integration with other system components and peripherals. 

The board has several test points that allow users to connect the BD14210G to a variety of test equipment. The test points are labeled, thus making it swift for users to identify the pins connected to the signals and simplify troubleshooting problems. The evaluation board monitors and senses currents in industrial and telecom equipment.
