LM48821 Overview
With its directly-coupled output technology, the LM48821 is a variable gain audio power amplifier capable of delivering 52mWRMS per channel into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply. The I2C volume control has a range of 76dB to 18dB. The LM48821's Tru-GND technology utilizes advanced charge pump technology to generate the LM48821’s negative supply voltage.
