SA58670ABS - 2.1 W/channel stereo class-D audio amplifier

Download the SA58670ABS datasheet PDF. This datasheet also covers the SA58670A variant, as both devices belong to the same 2.1 w/channel stereo class-d audio amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The SA58670A is a stereo, filter-free class-D audio amplifier which is available in an HVQFN20 package with the exposed Die Attach Paddle (DAP).

Key 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 SA58670A delivers 1.4 W/channel at 5.0 V and 720 mW/channel at 3.6 V into 8 Ω. It delivers 2.1 W/channel at 5.0 V into 4 Ω. The maximum power efficiency is ex.
