Audio amplifiers, or linear amplifiers, are devices designed to amplify a low-power audio signal, such as that coming from a microphone or other audio source. The LM4820ITP-6/NOPB is an audio amplifier made specifically for use in portable applications which offers superior performance, robustness, and flexibility compared to other audio amplifiers.

The LM4820ITP-6/NOPB is engineered to meet the requirements of a broad range of portable and handheld applications. It offers an optimal balance of performance, power efficiency, ruggedness, and cost effectiveness. It is the ideal audio amplifier for a variety of applications, ranging from Bluetooth speakers to portable media players.

The LM4820ITP-6/NOPB is a fully-differential, Class-AB linear audio amplifier. It is designed to amplify low-power audio signals to a level of up to 4.0V rms. It features a stereo BTL output, a differential input, and is designed to reduce RF susceptibility, making it ideal for use in portable applications.

The LM4820ITP-6/NOPB utilizes an external feedback resistor to control its gain and a feature which allows for the adjustment of its voltage gain. The gain of the LM4820ITP-6/NOPB can be set from 7.5dB up to 32.5dB in steps of 5dB. This feature allows the amplifier to meet the most stringent requirements of high-end applications, while also allowing for the device to be used in a variety of applications.

The LM4820ITP-6/NOPB also features a low-noise pre-amplifier which provides a maximum noise-floor as low as 2.3µVrms (8kHz bandwidth). This makes it ideal for applications that require a minimum of noise and distortion. The device also features a high signal-to-noise ratio (SNR) of up to 98dB.

The LM4820ITP-6/NOPB utilizes a single-ended power supply range of 2.6V to 6.0V, making it ideal for single-cell lithium battery applications. The device also features an on-chip thermistor for thermal protection and an adjustable click-and-pop suppression control. This control adjusts the click-and-pop suppression range between 1mV and 8V.

The LM4820ITP-6/NOPB is also available in a 0.8mm thick, 7mm x 5mm micro package size, with a height of 3mm. This makes it ideal for use in space-constrained applications. The device also features low quiescent current, which helps extend battery life.

In conclusion, the LM4820ITP-6/NOPB is an ideal audio amplifier for a variety of portable and handheld applications. It is a high-performance, robust and flexible linear audio amplifier which is designed to meet the most stringent requirements of high-end applications. It features a stereo BTL output, a differential input, adjustable gain, low-noise pre-amplifier, low quiescent current, a 0.8mm thick micro package, and adjustable click-and-pop suppression control.
