The Texas Instruments THS4500EVM is an evaluation board used to evaluate the company’s THS4500 high-performance current-feedback amplifier. This amplifier combines dual-channel current-feedback amplifier architecture, wide power supply range (±8 V to ±18 V), and wide output voltage swing (rail-to-rail) to deliver amplifier performance for a variety of applications.

The THS4500EVM board has two identical systems configured separately. These are both mounted with amplifiers (with gain set to 1 V/V) and one with an amplifier configured with gain set to 2 V/V. Each amplifier is configured with gain control (Gain/Attenuation and GR/AGR steps) and output impedance control (Tone, Layout and OPLG). Gain/Attenuation and GR/AGR steps are both adjustable for each amplifier\'s input, so that the gain can be adjusted independently.

The THS4500EVMs board is powered from an external user-supplied power supply (10 A, +15 V to +45 V) and can be powered with a range of 9 V to 18V (±15V to ±30V) input voltages. It is a highly versatile board that is designed for use in high frequency applications (up to 65 MHz), for high accuracy analog signal applications (gain-bandwidth up to 160 MHz), and for low distortion audio applications (S/N ratio of 64 dB).

The main features of the THS4500EVM board include adjustable gain and output impedance control for each amplifier channel, differential current outputs, and low noise and off-axis rejection. All of these features are designed in order to provide the highest performance in both analog and digital applications. The board also includes test points for both single-ended and differential measurements, and headers for connections to instruments. A wide range of analog inputs and outputs are also provided, making the board suitable for use with high-speed digital signals.

The board also incorporates an on-board diagnostic module which alerts the system to any faults such as over-voltage, over-temperature, and under-voltage. The various test points and instruments that can be used with the THS4500EVM board make it an ideal tool for debugging any problem that may arise in a design. The board is also designed for manufacturing tests, allowing manufacturers to quickly and accurately diagnose any issues during the production process.

Overall, the THS4500EVM board is an invaluable tool for designers who need to quickly and accurately measure the performance of their systems. With its adjustable gain and output impedance control, as well as its wide range of analog inputs and outputs, this board provides the ideal setup for evaluating high-performance current-feedback amplifiers.
