TAS5602 (ACTIVE) 20-W Stereo Digital Amplifier Power Stage with Feedback

20-W Stereo Digital Amplifier Power Stage with Feedback - TAS5602

Next Generation 30-W, Stereo, Analog Input Class-D Audio Amplifier:  TPA3118D2

Next Generation 30-W, Stereo Class-D Amplifier with Low-Idle Power Dissipation (Analog-In) for Battery Operated Systems Available:  TPA3128D2


The TAS5602 is a 20-W (per channel) efficient, stereo digital amplifier power stage for driving 4 single-ended speakers, 2 bridge-tied speakers, or combination of single and bridge-tied loads. The TAS5602 can drive a speaker with an impedance as low as 4Ω. The high efficiency of the TAS5602 eliminates the need for an external heat sink.

A simple interface to a digital audio PWM processor is shown below. The TAS5602 is fully protected against faults with short-circuit protection and thermal protection as well as overvoltage and undervoltage protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.
