The TDA1308 is an integrated class-AB stereo headphone driver from NXP. It is fabricated in a 1 μm CMOS process and has been primarily developed for portable digital audio applications.
The SA58635 is a stereo, class-G headphone driver with I2C-bus volume control. The I2C-bus control allows maximum flexibility with digital volume control, independent channel enable and mute control.
The output of the SA58635 is referenced around true ground zero. It is designed to operate at the low supply current of 1.5 mA making it battery friendly. A unique power management technique provides class-G power efficiency by using a buck converter to step down the battery supply from a typical l
