LM1875T General Description

The LM1875T is a monolithic power amplifier that delivers 20 watts of continuous average output power into an 8 ohm load. It operates on a wide supply voltage range of ±16V to ±60V and has a low distortion and high-quality sound output. The amplifier features a high gain of 90dB, which eliminates the need for an external preamplifier. The LM1875T has a built-in thermal shutdown mechanism to protect the amplifier from overheating, making it reliable and durable. It also has a mute function that allows the user to easily turn off the output signal when necessary. The amplifier is constructed with a robust design that ensures efficient heat dissipation and low distortion levels.
