The TDA2030A is a monolithic class-AB audio power amplifier from STMicroelectronics capable of delivering 18W into a 4Ω load at ±14V supply. The device features very low 0.08% total harmonic distortion at 8W output into 8Ω, making it suitable for hi-fi applications. The wide supply range (±6V to ±18V or 12V to 36V single-ended) provides flexibility for car audio, desktop speakers, and portable systems. Built-in thermal shutdown at 145°C and short-circuit protection on all pins ensure robustness in end-user products. The 5-pin Pentawatt package requires minimal external components, typically just input/output coupling capacitors and feedback network.

The TDA2030A uses a class-AB output stage with a differential input pair and voltage gain stage. The input stage is a PNP differential pair that provides the high 5MΩ input impedance and low 2mV input offset voltage. The voltage gain stage amplifies the differential signal, driving the class-AB output stage through a Vbe multiplier that sets the output stage bias current for minimal crossover distortion. The class-AB output stage uses complementary NPN/PNP transistors that each conduct slightly more than half the output cycle, eliminating the crossover notch of pure class-B designs. The 80dB open-loop gain provides ample loop gain for the 30dB closed-loop configuration, reducing THD to 0.08%. The closed-loop gain is set by external feedback resistors, with a typical configuration using 22kΩ feedback and 680Ω ground reference for 30dB gain. The 8V/µs slew rate ensures full power bandwidth well above the audio range. The thermal shutdown circuit monitors the junction temperature and reduces the bias current when it exceeds 145°C, gracefully limiting power dissipation without sudden output cutoff.

3 -VCC 电源 Negative supply (or GND for single supply)
4 输出 Analog Output Amplified audio output to speaker
5 +VCC 电源 Positive supply (+6V to +18V)
  • Hi-Fi Amplifiers: 0.08% THD delivers audiophile-quality sound in compact desktop and bookshelf speaker systems
  • Car Audio: 12V single-supply operation directly powers from vehicle battery; 18W output drives door speakers
  • Guitar Amplifiers: 3.5A peak output and wide supply range suit practice and performance amplifier combos
  • Active Subwoof: Bridge-tied load (BTL) configuration with two TDA2030A doubles output power for bass drivers
  • DIY Audio Projects: 5-pin package and minimal external components make it ideal for hobbyist amplifier builds
