The LM4832MTX/NOPB is a low-power, monolithic integrated circuit (IC) amplifier capable of providing exceptionally high audio quality. This IC ensures ergonomic design of high-quality audio systems, which simplifies the design and assembly process. The LM4832MTX/NOPB can be used to provide amplification for most audio applications, in addition to headphones and desktop audio applications. The LM4832MTX/NOPB is suitable for all general-purpose audio output stages, including portable amplifiers and cellular phones.
The LM4832MTX/NOPB is an operational amplifier which uses direct-coupled expander, negative feedback, and a novel circuit topology to achieve low-distortion performance. This IC is designed for wide-band audio applications and utilizes a proprietary power-boosting technique to generate higher output power under low supply voltage operation. This feature enables the device to achieve enhanced equipment performance and greater efficiency, while requiring less power.
The LM4832MTX/NOPB operates with a low voltage supply voltage of 3V, allowing for a wider range of accepted input signals which can be amplified and have their waveforms expanded even if they are close to the ground voltage. The LM4832MTX/NOPB also provides thermal protection against device overheating. This helps conserve energy, reduces system cost, and increases the overall performance of the device.
The LM4832MTX/NOPB amplifies an audio signal by taking an input signal and adding an offset voltage to expand it during the amplification process. This is achieved by the direct-coupled expander which takes an input signal and boosts it while adding extra levels of amplification. The actual course of amplification is determined by the amount of supply voltage to the device. When the supply voltage exceeds the given maximum rating, this enables the additional headroom for the output level of the signal.
The LM4832MTX/NOPB uses a unique architecture in its output stage, which consists of two op-amps with complementary output. Each op-amp serves its own pair of output driver transistors. This architecture ensures superior stability, improved noise suppression, and high audio quality performance from the device. This architecture also provides dynamic range, low output noise and low distortion.
The LM4832MTX/NOPB also features a slew rate control input, which can be used to adjust the device’s dynamic response. This input provides an effective way to limit high-frequency distortion and oscillation. Through proper setting of this signal, a wide range of audio applications is possible, including active speaker systems and high-performance, low distortion headphone amplifiers.
Overall, the LM4832MTX/NOPB is a low-power, monolithic integrated circuit (IC) capable of providing exceptional audio quality. It features a direct-coupled expander, negative feedback, proprietary power-boosting technique, and a unique op-amp output stage architecture. This IC can be used for various audio applications, including portable amplifiers, active speaker systems and headphone amplifiers. Thanks to its low operating voltage and slew rate control input, this device can provide superior stability and high audio performance.
