The TAS5110 incorporates TI’s equibit t technology and is used in conjunction with a digital audio PWM processor (TAS50xx) to deliver high-power, true digital audio amplification. The efficiency of this digital amplifier can be greater than 90%, reducing the size of both the power supplies and heat sinks needed. The TAS5110 accepts a mono PWM 3.3-V input and controls the switching of an internal CMOS H-bridge. When used with the TAS50xx PWM processor, system performance of less than 0.09% THD is attainable. Over-current protection, over-temperature, and under-voltage protections are built into the TAS5110, safeguarding the H-bridge and speakers against output shorts, over-voltage conditions, and other fault conditions that could damage the system.
