The AD8045ACP-EBZ is an evaluation board featuring ADI\'s AD8045 Precision Op Amp for current sensing. It is designed for high-accuracy current-sensing applications where the current to be sensed is in the range of +/- 20 mA to +/- 80 mA. The combination of high precision and low power consumption makes the AD8045ACP-EBZ an ideal choice for battery-powered systems where energy efficiency is critical.

The AD8045ACP-EBZ features two on-board precision op amps with a low power, low offset, low noise gain amplifier configuration. The board also features an adjustable gain circuit and provides a maximum offset voltage of 1.25 µV and 1.5% gain accuracy over a 10 mA to 80 mA range. The AD8045ACP-EBZ evaluation board also includes two precision offset trimming circuits to help optimize the offset performance.

The evaluation board includes an adjustable RFI shielding cover to minimize electromagnetic interference, and a termination shield to reduce electromagnetic interference from other boards. The board operates from a single +12 V supply, and the output is provided on two single ended connectors. The evaluation board also features a logic control input which can be used to select the gain and expand the dynamic range of the overall system.

The AD8045ACP-EBZ evaluation board is also filled with firmware to make the system conveniently programmable. LED indicators and SMBus compatible outputs are available for easy monitoring and diagnostics. The board also features an isolated SPI interface which allows the user to access the amplifier chip control register for programming and calibration.

The AD8045ACP-EBZ evaluation board utilizes ADI\'s advanced architectures to achieve very high feedback loop gain, and fast settling times, making it suitable for low-power, low-noise current-sensing applications. The evaluation board also supports a wide range of gain settings due to its adjustable gain circuit, allowing for applications like high-side current sensing. The AD8045ACP-EBZ evaluation board is ideal for applications where high-accuracy current-sensing and low power are needed, such as battery-powered systems, medical equipment, communications systems, automotive sensing, renewable energy systems, and many other applications.
