Evaluation and Demonstration Boards and Kits are widely used in various industries. For example, the TEA1936XDB1475UL is a widely used digital amplifier evaluation board. It provides modern components and features that simplify design, reduce development time, and help save valuable space.

The TEA1936XDB1475UL is a two-channel Class-D amplifier evaluation board that is intended for the development of audio products. It is suitable for applications in automotive Bluetooth, medical devices, and Consumer Audio applications. This evaluation board provides a complete system to verify and characterize TEA1936R applications.

The TEA1936XDB1475UL can rate up to 14.75W with a 2ohm output and a total harmonic distortion of less than 0.5%. Its standby mode is extricable too; it only consumes about 0.8mA and can be enabled and disabled in various ways. Users can set and measure both channels separately with an input voltage of 20mV. It also has a temperature protection feature, which monitors the die temperature of the chip and will automatically reduce the gain in order to keep the chip temperature below 130°C and protected against thermal damage.

The TEA1936XDB1475UL is based on the TEA1936R, a self-supplied, low-voltage, fully-monolithic Class-D Digital Audiopower amplifier. This IC features a switching architecture that efficiently converts any DC input into a high-fidelity audio power output. It is able to operate with a supply voltage of 2.2V up to 6V, and it achieves a very high efficiency, up to 80% or higher. What’s more, it also features a low-noise input stage, a sophisticated PWM modulator, and a wide-switching frequency range of 0.7 to 2.7 MHz.

The working principle of the TEA1936XDB1475UL is relatively simple. First of all, the power supply is connected to the board, which supplies power to the amplifier. The input signal is then connected to the input pins. The bipolar signal is then converted into a single-ended differential signal in order to increase the signal-to-noise ratio. This signal is then parsed into PWM and pulse-width modulation is applied to the signal. The PWM signal is then routed to the Class-D driver, which amplifies the signal and sends it to the loudspeaker for reproduction.

In short, the TEA1936XDB1475UL evaluation board is designed for those involved in the developing of audio products. It is an efficient and feature-packed tool, providing a wealth of features and components that allow users to quickly verify and characterize TEA1936R applications. Its design and feature set help reduce development time while allowing for optimal performance.
