The deflection coil is connected between the output amplifiers, which are driven in phase opposition. An external resistor (RM) connected in series with the deflection coil provides internal feedback information. The differential input circuit is voltage driven. An external resistor (RCON) connected between the differential input determines the output current through the deflection coil. The relationship between the differential input current and the output current is defined by: Idiff xRCON = Icoil xRM.The output current is adjustable from 0.5 A (p-p) to 2 A...
