"TPA01122-W音频功放器件技术规格及应用指南"

The TPA0112 is a stereo audio power amplifier with four selectable gain settings, designed for use in PC 99 desktop line-out applications. It is capable of delivering 2 watts per channel into a 3-ohm load, making it suitable for a wide range of audio systems. The internal gain control eliminates the need for external gain-setting resistors, simplifying the design and reducing component count. The TPA0112 features a PC-beep input and depop circuitry to minimize noise during power-up and power-down transitions. It also includes a stereo input MUX and fully differential input, providing flexibility for different audio input configurations. This power amplifier is designed for low supply current and shutdown current, minimizing power consumption in both active and standby modes. The surface-mount power packaging and 24-pin TSSOP PowerPAD make it suitable for compact and space-constrained designs. Overall, the TPA0112 is a versatile and efficient audio power amplifier with a range of features that make it suitable for various applications, including PC desktop line-out and other audio systems. Its compatibility with PC 99 standards, internal gain control, and low power consumption make it a strong choice for designers looking for a high-performance audio amplifier solution.
