The SY88913KC is a special purpose linear amplifier, designed to solve many of the special needs and challenges faced by most amplifier designs. It is designed to provide a versatile, high-performance, yet highly cost-effective solution for linear audio processing systems. The SY88913KC is suitable for many applications related to linear audio amplification, including audio processing, signal conditioning, and feedback correction for a wide range of audio loudspeakers and amplifiers. Additionally, this device is particularly well suited for use in systems requiring extremely wide dynamic range and high linearity, including digital and high quality stereo audio amplifiers.

The SY88913KC utilizes a double-balanced structure, which is an operating configuration with highly linear performance characteristics. This double-balanced design consists of two main components: the main amplifier and the matching network. The main amplifier has two symmetrical, complementary components, each with its own differential and output stages. The matching network is a passive filter with three sections: the input and output sections for the main amplifier, and the feedback section for the output stage. The input section provides conversion from the single-ended input signal to the double-balanced output signal, while the output section serves to match the double-balanced output signal to the desired transfer function. The feedback section provides the necessary feedback gain and equalization to achieve the desired output performance.

The SY88913KC can operate in both single-ended and differential modes, allowing it to be optimized for the application requirements. In the single-ended mode, the device is capable of up to 26 dB of overdrive and a 1:1 input-to-output gain, while in the differential mode the gain can be adjusted to between 0 and 15 dB with a 1:0.5 input-to-output gain. Additionally, the device supports power-on reset, as well as supply and output voltage monitoring. The device also features overload protection circuitry and adjustable input wave shaping, which can be used to minimize distortion due to high capacitive loads.

The SY88913KC is suitable for use in a wide range of applications, including audio power amplifiers, automotive audio systems, sound reinforcement systems, effects processors, and professional sound systems. Its versatility and high performance make it an ideal choice for many applications that require high linearity and wide dynamic range. Additionally, it is highly cost-effective, making it suitable for both commercial and home audio amplifiers.
