General description
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 lithium ion battery (4.8 V to 2.3 V). Efficiency is
further increased by allowing the output amplifier/driver to operate at multiple voltage rails
based on the output/input swing.
The SA58635 delivers 2
× 25 mW minimum into 16 Ω and 32 Ω loads. The SA58635
provides thermal shutdown and self limiting current protection.
The SA58635 is a high fidelity HP driver amplifier with a S/N of 100 dB minimum. An
excellent PSRR of more than 100 dB, differential input circuit topology allows for
maximum noise immunity in the noisy mobile phone environment.
The SA58635 is available in a 16-bump WLCSP (Wafer Level Chip-Size Package) making
it ideal choice for cellular handsets and portable media players.
