General description
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 utilizing G0 and G1 gain select pins. 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 V and 720 mW/channel at 3.6 V into 8
. It
delivers 2.1 W/channel at 5 V into 4
. The maximum power efficiency is excellent at
70 % to 74 % into 4
and 84 % to 88 % into 8
. The SA58670 provides thermal and
short circuit shutdown protection.
