The internal structure schematic diagram of UC3907 IC chip

Published:2012/12/13 1:00:00 Author:Ecco | Keyword: internal structure , IC chip | From:SeekIC

Operating supply voltage range V (10 feet) is 4.5 ~ 35 V; chip has a reference voltage source VREF, and its value relative to ARTIFICIAL GND (6 feet ) is 1.15 V which can output from VREF (7 feet ); ARTIFICIAL GND is the low resistance ground ( ground reference ) of chip, and its level is higher 0.25V than (-) SENSE (4 feet), and the voltage bias provides loop circuit for the the grounded amplifier current, while the voltage sampling negative terminal ( - ) Sense ( i.e. grounded amplifier inverting input terminal ) has a high input impedance.
