1 / 28 page  February 2008 Rev 2 1/28 28 TS4601 High performance stereo headphone amplifier with capacitorless outputs and I2C bus interface Features ■ Power supply range: 2.9 V to 5.5 V ■ 107 dB of PSRR at 217 Hz ■ Fully differential inputs ■ I²C interface for volume control ■ Digital volume control range from -60 dB to +4 dB ■ 101 dB of SNR A-weighted ■ Independent right and left channel shutdown control ■ Low quiescent current: 4.8 mA typ. at 3.0 V ■ Low standby current: 2 µA max ■ Output-coupling capacitors removed ■ Flip-chip package 2.1 mm x 2.1 mm, 500 µm pitch, 16 bumps Applications ■ Cellular phones ■ Notebook computers ■ CD/MP3 players Description The TS4601 is a stereo headphone driver dedicated to high audio performance and space- constrained applications. It is based on low power dissipation amplifier core technology. Special care was taken in the design of the amplification chain to achieve peerless PSRR (107 dB typ. at 217 Hz) and 101 dB of SNR. The TS4601 can drive 0.9 Vrms output voltage into 16 Ω and 1.6 Vrms into 10 kΩ, whatever the power supply voltage, in the 2.9 V to 5.5 V range. An I²C interface offers volume control in 64 steps from -60 dB to +4 dB and multiple configuration modes for the device. The traditionally used output-coupling capacitors can be removed and a dedicated common-mode sense pin removes parasitic noise from the jack. The TS4601 is designed to be used with an output serial resistor. It ensures unconditional stability over a wide range of capacitive loads. The TS4601 is packaged in a tiny 16-bump flip- chip with a pitch of 500 µm and a 300 µm diameter ball size.
