TS4621E规格书详情

描述 Description

The TS4621E is a class-G stereo headphone driver dedicated to high audio performance, 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 buck converter for supplying this amplifier.
When powered by a battery, the buck 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 TS4621E is designed to be used with an output serial resistor. It ensures unconditional stability over a wide range of capacitive loads.
The TS4621E is packaged in a tiny 16-bump flip-chip package with a pitch of 400 μm.
