TDA8926TH is a 2 x 50W class-D audio amplifier. It features high efficiency (>94%), low quiescent current, high output power, load short-circuit protection and diagnostic output.
The TDA8926TH is a digital power stage for a two‑chip class‑D audio amplifier system, delivering up to 2 × 50 W output power. It operates from a wide supply range and includes protection features such as over‑temperature and short‑circuit detection.
Key features include high efficiency (>94%), low quiescent current, and BTL operation for increased power. The datasheet lists detailed electrical characteristics, pin configurations, thermal data, and recommended soldering methods for the HSOP24 package.
| Supply voltage range | ±15 V to ±30 V |
|---|---|
| Typical efficiency | >94 % |
| Maximum short‑circuit current | 5 A |
| Thermal resistance (junction‑to‑ambient) | 40 K/W |
| Package | HSOP24, 24‑lead plastic with small heatsink |
It operates from ±15 V up to ±30 V supply voltage.
If the junction temperature exceeds 150 °C, the DIAG pin goes low to signal an over‑temperature condition.
The device detects a short‑circuit when the output current exceeds 5 A and activates the diagnostic output.
