The Texas Instruments LM4855LQ is an audio power amplifier system designed for portable handheld applications such as cellular phones and PDAs. It is capable of delivering 1.1W of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, or 115mW per channel into stereo 32Ω BTL loads with 0.5% THD+N, using a 5V power supply.
This amplifier features a 32-step digital volume control and eight distinct output modes, all programmable via a three-wire SPI serial control interface. This interface allows for flexibility in routing and mixing audio channels. The LM4855LQ includes "click and pop" suppression circuitry and thermal shutdown protection for enhanced reliability. It operates from a single supply voltage ranging from 2.6V to 5.0V and has a low shutdown current of 0.1µA typical.
The LM4855LQ is available in DSBGA and WQFN surface-mount packages. The DSBGA package is particularly space-efficient, utilizing only 2mm x 2.3mm of PCB space, making it suitable for compact designs. The device requires only six external components, simplifying board layout and reducing overall system cost.
