The TDA8929T is a controller IC for a two‑chip class‑D audio power amplifier system. It supports both stereo single‑ended (SE) and mono bridge‑tied load (BTL) configurations, offering high efficiency and low quiescent current across a supply range of +15 V to +30 V.
The document provides detailed functional descriptions, pin assignments, electrical characteristics, and reference designs, along with ordering information and package details for designers and engineers.
| Supply voltage (Vp) | +15 V to +30 V |
|---|---|
| Quiescent current | 20 mA to 30 mA |
| SE voltage gain | 29 dB to 31 dB |
| SE input impedance | 45 kΩ to 68 kΩ |
| BTL voltage gain | 35 dB to 37 dB |
| BTL input impedance | 23 kΩ to 34 kΩ |
The device operates from +15 V up to +30 V supply voltage.
It can be used as a mono Bridge‑Tied Load (BTL) amplifier or as a stereo Single‑Ended (SE) amplifier.
