SY88289HLMG application field and working principle

The SY88289HLMG is a linear-amplifier special-purpose power amplifier module manufactured by Seoul Semi-Conductor, and is used mainly in automotive audio and audio processing applications. This amplifier module uses a high-end hybrid MOSFET process to deliver exceptional performance with respect to voltage gain and signal-to-noise ratio (SNR). The amplifier module also integrates high-efficiency power transistors, as well as a built-in active current-mode switch to enable differential inputs. This high-end power amplifier module is designed to provide excellent power handling capacity and distortion characteristics, even at high frequencies. Furthermore, it provides a high level of immunity from external noise interference, and is capable of operating at temperatures up to 85°C.

The SY88289HLMG is designed to provide high voltage gains and signal-to-noise ratios (SNR). This amplifier module is based on two main types of amplifiers: bipolar transistors and MOSFETs. The bipolar transistors and MOSFETs are arranged in a complementary, differential configuration. This amplifies the difference between two signals, while providing low distortion and high gain.

The SY88289HLMG provides high dynamic range and excellent linearity, with a voltage gain of 90dB and an SNR of 96dB. It utilizes an active current-mode switch to enable differential inputs and an on-board reset circuit to allow the amplifier to return to idle upon power up. Additionally, the amplifier module includes a built-in protection circuit to protect against over-current, as well as temperature and voltage protection. Also, the amplifier module has a low output impedance, which reduces power dissipation and increases power output.

The operation of the SY88289HLMG is based on the principle of power amplification. A power amplifier is an electronic device that amplifies an electrical signal from a source device to a higher amplitude, which can then be used to drive an electrical load. This amplifier module is designed to be used in audio or audio processing applications and has a voltage gain of 90dB and an SNR of 96dB. The SY88289HLMG uses a high-end hybrid MOSFET process to deliver exceptional performance.

To operate efficiently, the SY88289HLMG requires a power supply voltage of 4.1V to 34V and a supply current of 20mA to 25mA. When operating at a supply voltage of 20V and a supply current of 25mA, the amplifier module has a voltage gain of 90dB and an SNR of 96dB. In addition, the amplifier module has a low output impedance, which reduces power dissipation and increases power output.

The SY88289HLMG is an ideal power amplifier module for automotive audio and audio processing applications. Its high voltage gain, low output impedance, and high signal-to-noise ratio make it well-suited for these applications. It is designed to provide high levels of performance and reliability and has built-in protection circuits and on-board reset circuits to ensure its long-term stability.
