LM4845 Output Capacitor-less Audio Subsystem

LM4845 Description

March 2005 www.DataSheet4U.com LM4845 Output Capacitor-less Audio Subsystem with Programmable National 3D LM4845 Output Capacitor-less Audio Subsyst.
The LM4845 is an audio power amplifier capable of delivering 500mW of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, 2.

LM4845 Features

* a 32-step digital volume control and eight distinct output modes. The digital volume control, 3D enhancement, and output modes (mono/SE/OCL) are programmed through a two-wire I2C or a three-wire SPI compatible interface that allows flexibility in routing and mixing audio channels. The LM4845 has thr

LM4845 Applications

* It delivers high quality output power from a surface-mount package and requires only seven external components in the OCL mode (two additional components in SE mode). Key Specifications j THD+N at 1kHz, 500mW into 8Ω BTL (3.3V) j THD+N at 1kHz, 25mW 1.0% (typ) 1.0% (typ) 2.7 to 5.5V 2.2 to 5.5V
