Part Number: SA58672
Function: 3.0 W, Mono Class-D audio amplifier
Package: HVSON10, WLCSP9 Type
Manufacturer: NXP Semiconductors.
The SA58672 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 device features shutdown 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 IC delivers 1.7 W at 5 V and 800 mW at 3.6 V into 8Ω. It delivers 3.0 W at 5 V and 1.6 W at 3.6 V into 4Ω. The maximum power efficiency is excellent at 90 % into 8Ω and 84 % to 88 % into 4Ω. The SA58672 provides thermal and short-circuit shutdown protection.
