STMicroelectronics TDA7491MV13TR Audio Amplifier
The TDA7491MV13TR from STMicroelectronics is a high-performance, dual-channel Class-D audio amplifier that offers an exceptional audio experience for a wide range of applications. It is part of STMicroelectronics' esteemed audio amplifier product line, designed to provide efficient power amplification with minimal heat dissipation and power loss.
This audio amplifier IC is capable of delivering up to 20 watts per channel into an 8-ohm load, which makes it a suitable choice for home audio systems, multimedia speakers, and portable audio applications. With its advanced PWM technology, the TDA7491MV13TR ensures high-quality sound reproduction with low total harmonic distortion (THD) and noise.
The device operates over a wide supply voltage range from 10V to 26V, allowing it to be used in various power environments and applications. Its efficiency is further enhanced by an adjustable modulation frequency (up to 1MHz) and a spread spectrum option that reduces electromagnetic interference (EMI), making it easier to meet regulatory requirements.
Key features of the TDA7491MV13TR include:
- 20W + 20W output power at THD = 10% with an 8-ohm load and Vcc = 24V
- Wide-range single-supply operation (10V - 26V)
- High efficiency, reducing the need for an external heat sink
- Four selectable, fixed gain settings for precise sound control
- Standby and mute features for power-saving and noise-free operation
- Overcurrent, short-circuit, and thermal overload protection circuits for improved reliability
The TDA7491MV13TR comes in a compact VFQFPN 36 lead-free package, which is ideal for space-constrained applications. Its exposed pad-up (EPU) package enhances thermal dissipation, ensuring stable operation across different temperature ranges.
With its combination of power efficiency, sound quality, and robust protection features, the TDA7491MV13TR stands out as an excellent choice for designers looking to incorporate a reliable and high-performing audio amplifier into their next project. Whether it's for consumer electronics or professional audio equipment, this amplifier is engineered to deliver outstanding performance and value.
