THS4502EVM

Evaluation boards are designed specifically to aid in the development and testing of complex integrated circuits, or ICs. Such boards facilitate repairs and tweaking of existing circuits, as well as encourage new designs for emerging products. The THS4502EVM is an example of an evaluation board developed to evaluate and characterize the THS4502, an analog, precision, high-speed, low-power operational amplifier integrated circuit from Texas Instruments Inc. (TI).

The THS4502EVM evaluation board measures and characterizes the THS4502 device. The board is designed to provide all the common test conditions for the THS4502 in an easy-to-use system. The board is fully populated with the THS4502 device, evaluation software, and the necessary user-configurable device options. These options allow the user to quickly change the performance of the THS4502 in the board.

The THS4502EVM board is designed for use with the THS4502 high-speed op-amp from TI. The SOC integrates a high-gain, low-distortion op-amp and proprietary switch mode feedback circuitry into an 8-pin SOIC package. It can operate over a wide supply voltage range for low-voltage applications. It offers a low quiescent current, wide common mode voltage range and superior CMRR and PSRR performance. In addition, it has fast settle time, which is important in dynamic signal applications. The THS4502 also offers an adjustable gain and bandwidth option, which makes it suitable for a wide range of applications in professional audio, medical, and automotive design environments.

The THS4502EVM uses the proprietary switch mode feedback circuitry of the THS4502 to achieve high performance. Multiple gain bandwidth options that have been pre-programmed into the board provide testing flexibility. The three choosable user-selectable gain options are: unity (1), 10X, and 100X. These options are convenient as they can quickly be adjusted without the need to replace any components.

The board includes the necessary components to set the power supply voltages, and a (2) 9V battery as the supply voltage. The included on-board power supply regulates the voltage to 5V and 4.7V, depending upon the needed tests. The user-configurable supply options provide the user with the ability to quickly change the power supply voltage depending on the application, making the THS4502EVM a good choice for low-voltage op-amp designs.

The board has a wide range of outputs for testing the THS4502 device. A variety of ports are available for a variety of test connections, including logic and analog signals. The pinouts, as well as the bus widths, are user-configurable, which provides design engineers with the flexibility to quickly adjust the board to their specific needs.

In addition to the ports, the board also contains a series of LEDs to provide visual feedback throughout the testing process. The LEDs are user-configurable and can be quickly tailored to the specific test conditions.

The THS4502EVM Evaluation Board possesses several features to facilitate a wide range of applications, such as professional audio, medical, and automotive applications.
