25W stereo Class D in a PowerSSO-36 — what it fits
The STMicroelectronics TDA7492P13TR is a 25W-per-channel Class D stereo amplifier in a PowerSSO-36 EPD package. It delivers 25W x 2 into 8Ω loads from a supply rail between 8V and 26V, making it a direct fit for powered speakers, soundbars, TV audio boards, and small-format pro-audio monitors where a compact surface-mount footprint and high efficiency matter. The Class D topology keeps heatsinking minimal compared to a linear amp at this power level — useful when the enclosure has limited airflow or the PCB is shared with a digital processor.
Supply voltage and output power — the real trade-off
The 25W x 2 @ 8Ω rating is specified at the upper end of the 8V–26V supply range. Dropping to a 12V rail will reduce output proportionally.
Lifecycle and sourcing — still a current-production part
The TDA7492P13TR carries an Active lifecycle status with ROHS3 compliance. No last-time-buy or NRND notices are on record.
