Description
- The TPA3112D1PWP is a 25W Mono Filter-free Class-D Audio Power Amplifier with SpeakerGuard™ for driving bridged-tied stereo speaker. Advanced EMI suppression technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard™ speaker protection system 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 TPA3112D1 can drive a mono speaker as low as 4R. The high efficiency >90% eliminates the need for an external heat sink when playing music. The outputs are fully protected against shorts to GND, VCC and output-to-output.
- 25W into an 8R load at <0.1% THD+N from a 24V supply
- 20W into 4R load at 10% THD+N from a 12V supply
- 94% Efficient class-D operation eliminates need for heat sinks
- Filter-free operation
- SpeakerGuard™ speaker protection includes adjustable power limiter plus DC protection
- Flow through pin out facilitates easy board layout
- Robust pin-to-pin short-circuit protection and thermal protection with auto recovery option
- Excellent THD+N/pop-free performance
- Four selectable, fixed gain settings
- Differential inputs
- Green product and no Sb/Br
- This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
