TS4601BEIJT

The TS4601B is a stereo headphone driver dedicated to high audio performance and spaceconstrained applications. It has the same uses as the TS4601 which it replaces, while offering highly improved ESD ratings.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 TS4601B can drive 0.9 V_rms output voltage into 16 O and 1.6 V_rms into 10 kO, 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 TS4601B is designed to be used with an output serial resistor. It ensures unconditional stability over a wide range of capacitive loads.The TS4601B is packaged in a tiny 16-bump flipchip with a pitch of 500 µm and a 300 µm diameter ball size.
