1. All voltage values are measured with respect to the ground pin.
2. The device is protected in case of over temperature by a thermal shutdown active @ 150.
3. Exceeding the power derating curves during a long period may provoke abnormal operation.
4. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5. Machine model: A 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating.
6. The measurement is performed on the evaluation board, with an STMicroelectronics ESD protection EMIF02-AV01F3


Description

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 Vrms output voltage into 16 and 1.6 Vrms into 10 k, 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 m and a 300 m diameter ball size.
