The TPA3002D2PHPR from Texas Instruments is a Class D stereo audio amplifier delivering 9W per channel into an 8Ω load. It integrates depop circuitry, differential inputs, and a full suite of protection — short-circuit, thermal shutdown, and a dedicated shutdown pin. The 48-HTQFP package (7x7 mm) keeps the footprint compact for portable or space-constrained audio gear. Supply range is 8.5V to 14V, and the part is rated for industrial temperature environments from -40°C to 85°C.
9W per channel — what it means for the speaker load
9W x 2 into 8Ω is the continuous output per channel. An 8Ω load is the design target.
Built-in protection and volume control
Depop eliminates the power-on thump that otherwise needs an external muting relay. Differential inputs reject ground-loop noise — useful when the audio source and amp share a power rail with a motor or switching regulator. The volume control is a DC voltage input, not a digital pot, so you set gain with a resistor divider or a DAC output. Short-circuit and thermal protection are on-die; no external current-sense resistors needed. This feature set keeps the BOM count low for a stereo amp block.
Lifecycle and compliance
Texas Instruments lists the TPA3002D2PHPR as Active with ROHS3 compliance. No NRND or EOL notice is on record.
