The NCP2811AMTTXG is a high-efficiency, high-performance audio amplifier in the Linear-Amplifiers-Audio category. This amplifier is a highly integrated Class D audio amplifier that offers both high-efficiency and low distortion. It is especially suitable for use in portable, battery-operated audio applications.

The NCP2811AMTTXG includes a temperature-compensated feedback control circuit, making it able to maintain low distortion across a wide temperature range. This feature enables the device to offer superior performance in both low and high temperature environments. In addition, it is able to operate with a high “standby” mode current efficiency of 0.45% at a single-ended class-D input, resulting in reduced power consumption. The NCP2811AMTTXG also features a low-noise preamplifier, making it ideal for use in noise-sensitive applications.

The NCP2811AMTTXG operates in either Stereo or Mono configuration and is able to drive speakers up to 1.6W in 4Ω at a single-ended power level or 2.4W in 4Ω at a differential power level. It is housed in a small, space-saving SOT-23-5 package, making it a great choice for applications where board space is limited. Other features include output short-circuit protection, an integrated Auto-Mute feature, and a thermal shutdown mode that disables the amplifier when overtemperature conditions are detected.

The NCP2811AMTTXG employs a PWM switching scheme to produce a high quality audio output. This scheme requires a pulse-width modulation signal to be applied to the device’s inputs in order to generate the necessary audio signals. The PWM switching scheme is a highly efficient method of converting an input audio signal into an amplified audio output. The major advantage of this scheme is that it allows the audio output to remain distortion-free even at high volumes.

The NCP2811AMTTXG also features an integrated one-wire digital audio interface that allows the device to be controlled using an integrated digital audio source, such as a cell phone or a tablet. This interface allows the device to receive and transmit data directly to a digital audio source and ensure a clear, distortion-free audio output.

Overall, the NCP2811AMTTXG is an excellent choice for applications requiring simple, efficient, and reliable audio amplification. It is well-suited for use in portable, battery-operated audio applications and offers superior performance and low-distortion levels. Due to its small size, it is ideal for applications with limited board space, and its integrated Auto-Mute feature and thermal shutdown mode help to protect the device and speaker from any sudden surges in temperature or audio output.
