The TS4994EIJT is a high-efficiency mono audio power amplifier integrated circuit (IC) component manufactured by STMicroelectronics. It is specifically designed for applications that require low voltage operation and high output power.
This audio amplifier IC is a Class D amplifier, which means it efficiently switches the power supply to minimize power losses and reduce heat dissipation. This results in higher energy efficiency and a compact form factor.
The TS4994EIJT operates with a power supply voltage range of 2V to 5.5V, making it suitable for portable devices and battery-operated applications. It provides a maximum output power of 3.2W, making it ideal for small speakers and headphones.
One of the key features of this IC component is its low power consumption. It incorporates an advanced modulation scheme that reduces quiescent current to minimize power drain when idle. This contributes to longer battery life in portable devices.
Another notable feature is the built-in DC volume control function, which allows precise volume adjustment without the need for external components. This simplifies the overall design and reduces costs.
Moreover, the TS4994EIJT has excellent audio quality with a signal-to-noise ratio greater than 100dB. It also offers a wide frequency response and low total harmonic distortion, ensuring a clear and distortion-free audio output.
Furthermore, this IC has built-in short-circuit and thermal protection mechanisms, which safeguard the device from damage under adverse conditions
