The LM4855LQ is an integrated audio amplifier system designed for portable applications like mobile phones and PDAs. It delivers 1.1W of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, and 115mW per channel into stereo 32Ω BTL loads with 0.5% THD+N, operating from a single 2.6V to 5.0V supply.
Key features include a 32-step digital volume control and eight distinct output modes, all programmable via a three-wire SPI serial control interface. This allows for flexible audio routing and mixing. The amplifier also incorporates "click and pop" suppression circuitry and thermal shutdown protection for enhanced reliability.
The LM4855LQ is available in space-efficient DSBGA and WQFN surface-mount packages. The DSBGA package, in particular, utilizes only 2mm x 2.3mm of PCB space, making it a highly space-efficient audio subsystem solution. It requires only six external components for operation.
