... Power ground and sense ground The TEA1762T has two ground connections. The sense ground ensures an increased accuracy of the output voltage of the switched mode power supply and can also be used to compensate for cable losses on the output of the converter. The grounds are internally connected via two anti-parallel diodes ...
