LM4860MX

Audio Amplifiers Overview

The LM4860MX is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It operates on a single power supply ranging from 2.7 V to 5.5 V and delivers an output power of 1.15 W into an 8 Ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.72% and draws a typical operating supply current of 7 mA. It is housed in a SOIC-Narrow-16 surface-mount package and functions within a temperature range of -20°C to +85°C.
