The Texas Instruments TPA4860 is a 1-W mono audio power amplifier designed for bridge-tied load (BTL) applications. It delivers 1 W of continuous average power into an 8-ohm load at 0.4% THD+N from a 5-V supply, suitable for voiceband frequencies.
This amplifier supports both 3.3-V and 5-V operation and eliminates the need for external output coupling capacitors in most designs. The gain is externally configurable via resistors, ranging from 2 to 20 without requiring compensation. Key features include a shutdown function for power-sensitive applications and headphone interface logic that mutes the output when speaker drive is not needed.
Internal thermal and short-circuit protection enhance device reliability. The TPA4860 is available in a 16-pin SOIC surface-mount package, facilitating automated assembly and reducing board space. Its high power supply rejection ratio of 56 dB at 1 kHz is beneficial for noise-sensitive audio circuits.
This device is drop-in compatible with the LM4860. The operating temperature range is -40°C to 85°C.
The power stage supply range is 2.7V to 5.5V and the analog supply range is 4.5V to 5.5V.
The TPA4860 is available in an SOIC package with surface-mount mounting.
