The Texas Instruments TPA4861DR is a 1-W mono, analog input, Class-AB audio amplifier designed for various audio applications. It delivers 1 W of continuous average power into an 8-Ω load at 0.2% THD+N from a 5-V power supply in voiceband frequencies.
This amplifier operates with a power stage supply voltage ranging from 2.7V to 5.5V and an analog supply voltage from 2.5V to 5.5V. It features a selectable gain, configurable from 2 to 20, and a shutdown mode for power-sensitive applications. The TPA4861DR includes internal thermal and short-circuit protection, and a high supply ripple rejection ratio of 56 dB at 1 kHz.
Designed for surface-mount packaging, the TPA4861DR comes in an 8-pin SOIC package, measuring 4.9 mm × 6 mm, which reduces board space and facilitates automated assembly. Its BTL (Bridge-Tied Load) configuration eliminates the need for external output coupling capacitors in most applications.
The operating temperature range for this amplifier is -40°C to 85°C. It is compatible with TI's TPA4860 in stereo applications.
