SA58672UK,027 Product Details

The SA58672UK,027 is a mono, filter-free class-D audio amplifier, which is available in a 9 bump WLCSP (Wafer Level Chip-Size Package) and 10-terminal HVSON packages.

The SA58672UK,027 features shut down control. Improved immunity to noise and RF rectification is increased by high PSRR and differential circuit topology. Fast start-up time and very small WLCSP package makes it an ideal choice for both cellular handsets and PDAs.

The SA58672UK,027 delivers 1.7 W at 5 V and 800 mW at 3.6 V into 8 Ω. It delivers 3.0 W at 5 V and 1.6 W at 3.6 V into 4 Ω. The maximum power efficiency is excellent at 90 pct into 8 Ω and 84 pct to 88 pct into 4 Ω. The SA58672UK,027 provides thermal and short-circuit shut down protection.
