Texas Instruments TAS5132
The TAS5132 does not require power-up sequencing due to internal power-on reset. The efficiency of this digital amplifier is greater than 90% into 8 Ω, which enables the use of smaller power supplies and heatsinks. The TAS5132 has an innovative protection system integrated on chip, safeguarding the device against a wide range of fault conditions that could damage the system.FEATURES
