The Texas Instruments LM4667ITL is a highly efficient, fully integrated Class-D audio amplifier designed for single-supply operation. This mono amplifier delivers up to 1.3W of output power into a 4Ω load, with a low THD + N of 0.8% at 1 kHz. It features an analog input and a hardware control interface, making it suitable for various audio applications.
The LM4667ITL offers selectable gain options of 6dB or 12dB, providing design flexibility. Its innovative modulator eliminates the need for an external LC output filter, reducing component count and board space. The amplifier operates over a wide analog supply voltage range of 2.7V to 5.5V and has an operating temperature range of -40°C to 85°C.
Key electrical specifications include high efficiency ratings, such as 74% typical at 3V/100mW into 8Ω, 84% typical at 3V/450mW into 8Ω, and 86% typical at 5V/1W into 8Ω. It also features a low quiescent current of 3.5mA typical and a micro-power shutdown mode with a shutdown current of 0.01μA typical. The device includes "click and pop" suppression circuitry, short circuit protection, and a fast turn-on time of 5ms typical.
Available in space-saving DSBGA and VSSOP packages, the LM4667ITL is designed for applications requiring compact and efficient audio amplification. The DSBGA package measures 3.0625 mm², while the VSSOP package is 14.7 mm² (3 mm x 4.9 mm).
