SA58670 datasheet

( HVQFN20 Type)

Описание :

The SA58670 is a stereo, filter-free class-D audio amplifier which is available in an HVQFN20 package with the exposed Die Attach Paddle (DAP). The SA58670 features independent shutdown controls for each channel. The gain may be set at 6 dB, 12 dB, 18 dB or 24 dB with gain select pins G0 and G1. Improved immunity to noise and RF rectification is increased by high PSRR and differential circuit topology. Fast start-up time and small package makes it an ideal choice for both cellular handsets and PDAs.

The SA58670 delivers 1.4 W/channel at 5.0 V and 720 mW/channel at 3.6 V into 8Ω. It delivers 2.1 W/channel at 5.0 V into 4Ω. The maximum power efficiency is excellent at 70 % to 74 % into 4Ωand 84 % to 88 % into 8Ω. The SA58670 provides thermal and short-circuit shutdown protection.
