LM1875T/LF03 Description

Short technical summary and product information.

The LM1875T/LF03 from Texas Instruments is a monolithic power amplifier designed for high-quality audio performance in consumer applications. It delivers up to 20 watts into a 4 or 8 ohm load using ±25V supplies, and can provide over 30 watts with an 8 ohm load and ±30V supplies.

 

This amplifier features very low distortion, with a typical THD+N of 0.015% at 1 kHz and 20W. It operates with a wide power bandwidth of 70 kHz and offers a typical gain of 90 dB. The device is designed to require minimal external components and includes built-in protection against AC and DC short circuits to ground, as well as thermal shutdown.

 

The LM1875T/LF03 supports analog input and has a mono speaker output. It operates from a wide analog supply voltage range of 16V to 60V and has a high current capability of 4A. The amplifier is internally compensated and stable for gains of 10 or greater. It is housed in a TO-220 package suitable for through-hole mounting.

 

Key electrical characteristics include a minimum load impedance of 4 ohms and an operating temperature range of 0°C to 70°C. The device also boasts 94 dB ripple rejection, enhancing audio signal purity.
