The Texas Instruments TPA3137D2PWPR is an efficient Class-D audio power amplifier designed for driving stereo speakers. It can deliver up to 6W per channel into 6-ohm loads from a 12V supply, or 6W into 8-ohm loads from a 13V supply. For mono applications, it can provide up to 12W.
This amplifier operates with high efficiency, up to 90%, which eliminates the need for heat sinks. It features a wide supply voltage range from 4.5V to 14.4V and offers low total harmonic distortion plus noise (THD+N) of less than 0.05% at 1W into 4 ohms at 1kHz.
The TPA3137D2PWPR includes advanced EMI suppression technology with spread spectrum control, enabling the use of inexpensive ferrite bead filters and meeting EMC requirements. It also incorporates SpeakerGuard™ speaker protection, which includes power limiter and DC protection. Robust protection features include pin-to-pin, pin-to-ground, and pin-to-power short circuit protection, as well as thermal protection.
This device comes in a 28-pin HTSSOP package and operates over an ambient temperature range of -40°C to 85°C. It supports both single-ended and differential analog inputs and provides click and pop-free startup.
