TPA3136D2PWPR Description

Short technical summary and product information.

The Texas Instruments TPA3136D2PWPR is an efficient Class-D audio power amplifier designed for driving bridged-tied stereo speakers. It delivers up to 20W per channel into 6-ohm loads from a 12V supply or 8-ohm loads from a 13V supply, with a wide supply voltage range of 4.5V to 14.4V.

 

This amplifier boasts up to 90% efficiency, eliminating the need for heatsinks. It features enhanced EMI performance with spread spectrum technology and includes SpeakerGuard™ speaker protection, which offers power limiting and DC protection. The device also provides robust protection against pin-to-pin, pin-to-ground, and pin-to-power shorts, as well as thermal protection.

 

With a fixed gain of 26dB, the TPA3136D2PWPR supports single-ended or differential analog inputs and offers click-and-pop-free startup. It operates within a temperature range of -40°C to 85°C and is available in a 28-pin HTSSOP package.

 

Applications include home audio systems, TV soundbars, and other speaker-driving applications where high efficiency and low EMI are critical.
