The BD88220GUL-E2 is an audio linear amplifier designed for applications ranging from general-purpose audio amplification to high-end audio systems and other signal processes. It can drive loads up to 450W of low distortion active speakers, and has low cross-over distortion levels and low noise at high power levels. Moreover, the device can produce up to 600W of total output power, responding to a wide range of frequencies ranging from 10kHz to more than 100kHz.

The BD88220GUL-E2 features a high-gain input stage combined with a state-of-the-art output stage. This combination provides superior performance in frequency response, Phase-Locked Loop (PLL) control and load sensitivity due to the high-precision design on the input stage. Furthermore, its ultra-low feedback design allows for superior high-frequency control and maximum power efficiency in high power applications.

The BD88220GUL-E2 features a Multi-Stage Amplification System (MSAS) which provides excellent sound quality and dynamic range. The MSAS stages consist of a differential input stage, a voltage-source output stage, and a current-source output stage. The current-source output stage is especially suitable for multi-channel applications, as it provides excellent bass control, wide frequency response and improved power efficiency.

The BD88220GUL-E2 working principle is based on a transconductance amplifier technique which is composed of two complementary transistors connected in the feedback loop. This allows the BD88220GUL-E2 to operate at very low distortion levels even with low input signals. Moreover, the use of dynamic negative feedback circuit and active compensation result in significantly reduced output distortions and improved load current waveforms.

The BD88220GUL-E2 has a wide range of applications, from general-purpose audio amplifiers to high-end audio systems and other signal processes. It can drive low-impedance active speakers with up to 450W of low distortion and features a multi-stages amplification system for superior sound quality. Furthermore, its ultra-low feedback design provides superior high-frequency control and maximum power efficiency for high power applications. As it is based on transconductance amplifier technique, the device can operate at very low distortion levels even with low input signals.
