Description

The TS4601B is a stereo headphone driver

dedicated to high audio performance and space-

constrained 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

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 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 flip-

chip with a pitch of 500 µm and a 300 µm

diameter ball size.
