The TPA0243DGQR (herein referred to as the “TPA0243”) is a linear audio amplifier integrated circuit, meaning it amplifies audio signals using a linear circuit, which by definition does not involve non-linear distortions. It is manufactured by Texas Instruments. The TPA0243 is commonly used for small-to-medium-powered audio applications in portable electronics, such as tablet computers and mobile phones. It is also used for automotive and commercial audio systems.

The TPA0243 is a dual-channel audio amplifier. It has an output power of up to 2 W per channel into 4 Ω as well as 55 dB of voltage gain and high-pass filter, allowing it to provide ample power to drive a speaker. The amplifier also features low-noise audio performance - it has a distortion level of less than 1.0% THD+N and a noise level of -71 dBV at 37.5 mVrms.

The TPA0243 is designed to be highly efficient. It has a power-down mode with a low quiescent current, allowing the device to conserve power when idle. It also features a thermal foldback function, which reduces the supply current at both increased temperature and over-current conditions. The TPA0243’s combination of efficient design and low power consumption makes it well suited for battery-powered applications.

The TPA0243 is designed to be compatible with a variety of audio sources. It is able to process both digital and analog audio signals from various sources, such as headphones, devices with a digital audio output, and computers. Additionally, the device has differential inputs, which allow it to reject noise from other devices and provide improved audio quality.

The TPA0243’s key features are its low power consumption, wide operating temperature range, and its ability to drive both 4-Ohm and 8-Ohm loads. Additionally, the device can be paired with other components to create complete audio systems. It can be combined with other Texas Instruments audio products such as the TPA0242, TPA0243DGKR, or the TPA5240DGKR.

The TPA0243 is a robust and reliable audio amplifier. Its low power consumption, wide temperature operating range, differential inputs, and ability to drive both 4-Ohm and 8-Ohm loads make it a suitable solution for a variety of audio applications. Its combination of features makes it an ideal choice for portable electronics, automotive audio systems, and commercial audio applications.
