The THS7313EVM is an evaluation and demonstration board that is created by Texas Instruments for the purpose of providing a platform to evaluate, characterize, and demonstrate the operation of the THS7313 dual-channel, low-power amplifier. This amplifier has low-voltage noise, low distortion, and high power efficiency, which makes it an ideal choice for a variety of applications.

The THS7313EVM has two operational modes, line driver and power amplifier. In line driver mode, the THS7313EVM is designed to drive loads with output levels up to 4V RMS and 3W RMS power levels at 10kHz, making it suitable for driving speakers, as well as other audio devices. In power amplifier mode, the THS7313EVM can provide up to 200 W peak power, enabling low-power applications such as multi-channel car audio systems.

The THS7313EVM uses a TS8000 series integrated circuit (IC) for power management that is capable of providing high frequency switching at up to 500 kHz. This IC is also capable of over-current and over-voltage protection to prevent damage to the device or other components connected to it. Additionally, the THS7313EVM contains an integrated thermal protection to ensure the device does not overheat.

The THS7313EVM can be powered from an external power source or an internal DC power source. The board has an output terminal for connection to external power supplies, as well as a 3V breakable jumper for connection to battery-powered systems. It also contains an I2S audio interfacing digital-to-analog converter (DAC) that allows the device to accept digital audio input from an external source.

The board has an adjustable gain structure that allows the user to select from a range of gain settings from 2.5 to 20 dB. This allows the user to adjust the level of amplified output according to their application requirements. Furthermore, the THS7313EVM contains a thermal protection circuit that can disable the amplifier operation at excessive temperatures to protect against overheating.

The THS7313EVM evaluation board is optimized for use in automotive audio systems, portable audio systems, and home audio systems. With its low voltage noise, low distortion, and high power efficiency, it is well-suited for a variety of audio applications. Furthermore, the board\'s ability to provide both line driver and power amplifier modes makes it a versatile platform for evaluation, characterization, and demonstration of the THS7313 dual-channel, low-power amplifier.
