LM4919 1.5V, Mono 85mW BTL Output, 14mW Stereo Headphone Audio Amplifier May 2004 LM4919 1.5V, Mono 85mW BTL Output, 14mW Stereo Headphone Audio Amplifier General Description The unity gain stable LM4919 is both a mono-BTL audio power amplifier and a Single Ended (SE) stereo headphone amplifier. Operating on a single 1.5V supply, the mono BTL mode delivers 85mW into an 8Ω load at 1% THD+N. In Single Ended stereo headphone mode, the amplifier delivers 14mW per channel into a 16Ω load at 1% THD+N. With the LM4919 packaged in the MM package, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output power. The LM4919 Features circuitry...
