... 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. ...
