SD2030

Overview

SD2030 is a low-frequency Class AB audio power amplifier IC featuring affordable cost, high output power, and low harmonic distortion. It is primarily used in high-fidelity stereo equipment and provides high-quality audio amplification. Key advantages: · Output power: typical 14W (THD=0.5%,VS=±14V,RL=4Ω); 12W into 4Ω and 8W into 8Ω with a ±14V dual supply or 28V single supply. · Harmonic distortion: total harmonic distortion (THD) is only 0.08% with optimized circuit design. · Protection: short-circuit protection, thermal protection, and automatic power-limiting ensure safe operation. · Package: TO220B5. Applications: SD2030 is widely used in high-fidelity stereo equipment, tape recorders, and computer powered speakers. Its performance and low cost make it suitable for these devices. Circuit structure and operation: SD2030 uses a standard BTL structure with two power amplifiers operating from the positive and negative supplies. It includes input, intermediate, and output stages; a small number of external components enables high-fidelity audio amplification. Power-supply noise, input-signal noise, and layout and grounding quality should be considered for optimum performance and stability.
