SLAS593B – JUNE 2008 – REVISED NOVEMBER 2008 20W STEREO DIGITAL AMPLIFIER POWER STAGE FEATURES 1 23 Supports Multiple Output Configurations – 2×20-W into a 8-Ω BTL Load at 18 V – 4×10-W into a 4-Ω SE Load at 18 V – 2×10W (SE) + 1×20W (BTL) at 18 V Thermally Enhanced Package – DCA (56-pin HTTSOP) Wide Voltage Range: 10V–26V – No Separate Supply Required for Gate Drive Efficient Class-D Operation Eliminates Need for Heat Sinks Closed Loop Power Stage Architecture – Improved PSRR Reduces Power Supply Performance Requirements – High Damping Factor Provides for Tighter, More Accurate Sound With Improved Bass Response – Constant Output Power Over Variation in Supply Voltage Single Ended Inputs Integrated Self-Protection Circuits Including Overvoltage, Undervoltage, Overtemperature, and Short Circuit With Error Reporting APPLICATIONS Flat-Panel, Rear-Projection, and CRT TV Consumer Audio Applications DESCRIPTION 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 s...
