STA540

The STA540 is a versatile audio amplifier integrated circuit that delivers high-quality sound amplification for a variety of applications. This chip is designed to drive a pair of speakers with an output power of up to 38W per channel while minimizing distortion and noise.

The STA540 features an embedded low-pass filter that eliminates high-frequency noise and provides excellent sound clarity. Additionally, it has a thermal and short-circuit protection system to prevent damage to the speakers or the amplifier in case of overheating or electrical faults.

With a wide range of supply voltage and robust architecture, the STA540 can operate in different configurations, including stereo, bridge-tied load (BTL), or parallel mode. Its flexibility makes it an excellent choice for various audio systems such as car amplifiers, home theatres, and professional sound equipment.

• The STA540 has the following features:
• 1. Two independent amplifiers with a maximum output power of 38W per channel
  2. Low distortion and noise THD+N ≤ 0.05% at 1kHz and 10W
  3. Built-in mute and standby modes for power saving
  4. Suitable for driving speakers with an impedance between 4Ω and 8Ω
  5. Wide operating voltage range between ± 7V and ± 25V
  6. Thermal and short-circuit protection to prevent damages to the system

The STA540 is an excellent choice for audio engineers who need an efficient, low-cost amplifier chip with high-quality sound performance.
