TPA112D is a kind of monolithic audio power amplifier IC which is integrated with two amps. It is a two-channel audio amplifier widely used in home theatres and other sound systems.This device has two inputs and two outputs, two-channel phase-locked loop (PLL) inputs, control input pin, and two power amplifier outputs. It can be used to drive any type of load, including a permanent magnet loudspeaker, electrostatic loudspeaker, etc.TPA112D provides excellent sound quality, low distortion, and low power consumption. It shows exceptional performance with adjustable volume and bass control. The integrated amplifier has thermal protection built-in, providing short circuit protection for the entire device automatically. Also, it is designed to withstand high temperature, humidity, and EMI radiation, which ensures long-term reliability.The TPA112D can be powered by both 12V and 24V power sources. It has a wide frequency range, from 20Hz to 20KHz ±3dB, smoothly curving down at both ends, making it ideal for high-end auditory devices. With an output power of ≤10W, it delivers a high degree of accuracy and tremendous sound clarity.The circuitry of TPA112D features an output amplifier and power controller. The amplifier\'s output stage consists of two complementary PNP/NPN transistors connected in push-pull configuration. The output stage is then cooled by a thermal protection module, in which the input signals are amplified.The power controller monitors the output power and adjusts the amplifier\'s voltage in order to reduce power consumption. The power device can detect the load and adjusts the output of the amplifier to achieve highest efficiency.The TPA112D is packed with various features, making it an ideal choice for high-end audio systems. It offers excellent sound quality, low power consumption, and adjustable volume and bass control. It is also thermally protected and designed to deal with high temperature, humidity, and EMI radiation. Lastly, it is able to sustain an output power of up to 10W without any distortion.The TPA112D can be used in a wide array of applications, ranging from home theatre systems to professional audio mixing setups. It is ideal for connecting multiple loudspeakers in a single system, as it has two inputs and two outputs. With its wide frequency range and exceptional sound clarity, the TPA112D is the perfect choice for a premium sound experience.
