TAS5086 5.1 Channel PWM Processor

• Six channel PWM Processor– Eight PCM inputs– Six PWM outputs– Stereo IIS lineout (5.1 channel downmix)

• Bass management (config 1)• Master/independent volume control• Symmetrical PWM• 100 dB dynamic range• PWM processor for Class AB price competitive

solution• AM avoidance algorithm• Automatic clock detection• Input/output mux

TAS5186 5.1 Channel Power Stage

• 200W, 5.1 channels in single package– 30Wx5/6 ohms– 60Wx1/3 ohms

• Two-stage over current detector– First Stage

• OC detector reset after each PWM cycle• Effectively acts as a current limiter• Prevents premature shutdowns due to high level music/source transients with

extreme speaker impedance drops• Low level click• Allows wider tolerance for speaker

– Second stage• OC shutdown occurs if first stage occurs for more than 1.5 ms

• Pre-charge control to reduce power-on/power-off/mute pops/clicks• Over-temperature, under-voltage protection• DDV, low profile package for cost-optimized applications• Used in conjunction with TAS5086 for class AB price competitive
