The TPA3138D2PWP from Texas Instruments is an analog input, Class-D audio amplifier designed for home audio, haptics, and piezo applications. It offers flexible power output, capable of delivering 2 x 10 W into a 6-Ω load or 1 x 18.5 W into a 4-Ω load, both at a 12-V supply.
This amplifier operates over a wide supply voltage range of 3.5 V to 14.4 V, making it suitable for battery-powered portable devices. Key electrical specifications include a typical THD+N of 0.04% at 1 kHz and a low idle current of 20 mA in 1SPW mode, contributing to longer battery life. The device features inductor-free operation, reducing solution size and cost, and is compliant with EN55013 and EN55022 EMC standards when inductors are not used.
Designed for ease of use, the TPA3138D2PWP supports single-ended or differential analog inputs and offers selectable gain settings of 20 dB and 26 dB. It includes integrated protections such as pin-to-pin, pin-to-ground, and pin-to-power short circuit protection, thermal protection, undervoltage protection, and overvoltage protection. The amplifier also features a power limiter and DC speaker protection. It comes in a 28-pin HTSSOP (PWP) package with dimensions of 9.7 mm x 6.4 mm.
This device is pin-to-pin compatible with TPA3110D2, TPA3136D2, and TPA3136AD2, offering a flexible upgrade path. Its high Class-D efficiency, exceeding 90%, and the absence of an external heatsink requirement further enhance its suitability for space-constrained designs.
