TEXAS INSTRUMENTS TPA3117D2EVM AUDIO POWER AMPLIFIER, EVALUATION MODULE
TEXAS INSTRUMENTS
The TPA3117D2EVM is an evaluation module for TPA3117D2 a 15W (per channel) efficient, Class-D audio power amplifier for driving bridged tied stereo speakers. Advanced EMI Suppression technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard speaker protection circuitry includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a "virtual" voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs. The TPA3117D2 can drive stereo speakers as low as 4Ω. The high efficiency of the TPA3117D2, 90%, eliminates the need for an external heat sink when playing music. 15W/ch into an 8Ω loads at 10% THD+N from a 16V supply 10W/ch into a 8Ω mono load at 10% THD+N from a 13V supply 90% efficient class-D operation eliminates need for heat sinks Wide supply voltage range allows operation from 8V to 26V Filter free operation Speakerguard speaker protection includes adjustable power limiter plus DC protection Flow trough pin out facilitates easy board layout Excellent THD+N / pop free performance Four selectable, fixed gain settings This EVM should be operated within the input range of -0.3V to 6.3V and the output voltage range of -0.3V to VCC+0.3V. Exceeding the specified input voltage range may cause damage to the EVM.
