  • The TS4621ML is a class-G stereo headphone driver dedicated to high-performance audio, high-power efficiency and space-constrained applications.

    It is based on the core technology of a low power dissipation amplifier combined with a high-efficiency step-down DC/DC converter for supplying this amplifier.
    When powered by a battery, the internal step-down DC/DC converter generates the appropriate voltage to the amplifier depending on the amplitude of the audio signal to supply the headsets. It achieves a total 2.1 mA current consumption at 100 μW output power (10 dB crest factor).
    THD+N is 0.02 % maximum at 1 kHz and PSRR is 100 dB at 217 Hz, which ensures a high audio quality of the device in a wide range of environments.
    The traditionally bulky output coupling capacitors can be removed.
    A dedicated common-mode sense pin removes parasitic ground noise.
    The TS4621ML is designed to be used with an output serial resistor. It ensures unconditional stability over a wide range of capacitive loads.
    The TS4621ML is packaged in a tiny 16-bump flip-chip package with a pitch of 400 μm.
