The SA58670BS/ABS are stereo, filter-free, class D audio amplifies that operate from a 2.5V to 5.5V supply. 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. Immunity to noise and RF rectification are increased by high PSRR and differential circuit topology. Fast start-up time and a small package makes it an ideal choice for portable and battery powered applications. The SA58670 delivers 1.4 W/channel at 5V and 720mW/channel at 3.6V into 8Ω. With a 4Ω load, it delivers 2.1W/channel at 5V. Additionally, the TTL level compliant SA58670 provides thermal and short-circuit shutdown protection. The parts are packaged in a HVQFN20 package with the exposed Die Pad.
