The TAS5261 is the highest power single-chip Class D power stage and delivers 110dB SNR for ultimate sound clarity in home audio applications. It drives > 300W into a 4-Ω speaker (10% THD+N) and can drive 125W, 8 Ω, at less than 0.09% THD+N with 95% efficiency. As part of TI’s PurePath Digital™ power stage product line it offers unparalleled power and current handling capability.

PurePath Digital
 
 KEY FEATURES
High power and current drive for the most demanding home theater systems
Total output power
 
125 W into 8 Ω at <0.09% THD+N
220 W into 6 Ω at 10% THD+N
315 W into 4 Ω at 10% THD+N
Class-D operation with extremely low on-resistance FETs enable greater than 95% efficiency that delivers pure power, not heat
Over-current protection against output shorts without unwanted shutdowns from speaker-impedance variations over frequency
The TAS5261 has complete protection circuitry integrated on chip, safeguarding the device and speakers against fault conditions that could damage the system.
