The Texas Instruments LM4819LD is a mono bridged Class-AB audio power amplifier designed for high-quality output power in a minimal PCB area. It is capable of delivering 350mW RMS output power into a 16Ω load or 300mW RMS output power into an 8Ω load with 10% THD+N from a 5V power supply.
This amplifier features an analog input and hardware control interface. It operates with an analog supply voltage ranging from 2V to 5.5V and a power stage supply also between 2V and 5.5V. The device is unity-gain stable and does not require output coupling capacitors, bootstrap capacitors, or snubber networks, making it ideal for low-power portable applications.
The LM4819LD is available in WSON, VSSOP, and SOIC surface-mount package types, offering flexibility for various application designs. Its minimal external component requirement further simplifies integration and reduces board space.
Key electrical characteristics include a typical THD+N of 1% at 1kHz and a shutdown current of 0.7μA. The operating temperature range is from -40°C to 85°C.
