SSM2250RUZ-REEL: Stereo Headphones Class AB Amplifier from Analog Devices

The SSM2250RUZ-REEL from Analog Devices is a stereo headphones class AB amplifier in a 14-lead TSSOP package. It is designed to drive headphones directly, without the need for an external output capacitor. The SSM2250RUZ features a high output current of 150 mA per channel, which is capable of driving even the most demanding headphones. It also has a very low total harmonic distortion (THD+N) of 0.003%, resulting in excellent sound quality.

The SSM2250RUZ is ideal for use in a wide range of portable and battery-powered applications, such as smartphones, tablets, MP3 players, and other audio devices. It is also well-suited for use in professional audio equipment, such as digital audio workstations (DAWs) and audio mixers.
