The Texas Instruments TPA4861D is a 1-W mono audio power amplifier designed for various audio applications. It utilizes a Class-AB input architecture and supports analog input signals. The amplifier is capable of delivering 1 W of continuous average power into an 8-Ω load with a THD+N of 0.12% at 1 kHz.
Key electrical specifications include a power stage supply voltage range of 2.7 V to 5.5 V and an analog supply voltage range of 2.5 V to 5.5 V. The gain is externally configurable via resistors, offering settings from 2 to 20 without requiring compensation. It also features a shutdown function for power-sensitive applications and a high supply ripple rejection ratio of 56 dB at 1 kHz.
The TPA4861D is housed in an 8-pin SOIC surface-mount package, measuring 4.9 mm × 6 mm with an area of 29.4 mm², which helps reduce board space and facilitates automated assembly. The device includes internal thermal and short-circuit protection for enhanced reliability. It is compatible with the LM4861 and works with the TPA4860 in stereo configurations.
The power stage operates from 2.7V to 5.5V, and the analog supply operates from 2.5V to 5.5V.
The TPA4861D is available in an SOIC-8 package with dimensions 4.9mm × 6mm and surface mount mounting.
The operating temperature range is -40°C to 85°C.
