摘要： A galvanic isolator having a transmitter die, a receiver die, and a lead frame is disclosed. The transmitter die includes an LED having first and second contacts for powering the LED, and the receiver die includes a photodetector. The lead frame includes first and second transmitter leads, and first and second receiver leads. The transmitter die is bonded to the first lead, the first contact being connected electrically to the first transmitter lead and the second contact being connected to the second transmitter lead. The receiver die is connected to the first and second receiver leads. The LED and the photodetector are positioned such that light generated by the LED is received by the photodetector. The first and second transmitter leads are capacitively coupled to the first receiver lead. The capacitive couplings are characterized by first and second capacitance values that are substantially the same.
