Notes
1. Up to 60 V
≥ VFB ≥ 40 V a decoupling capacitor CFB =22 F (between pins 7 and 5) and a resistor RFB = 100
(between pin 7 and VFB) are required (see Fig.7).
2. Saturation voltages of output stages A and B can be increased in the event of negative input currents I1, 2 < 500 A.
3.
with Ideflc = common mode deflection current and Iidc = common mode input current.
4. Deviation of the output slope at a constant input slope.
5. Frequency behaviour of Goi and Gofb:
a)
3 dB open-loop bandwidth (45°) at 15 kHz; second pole (135°) at 1.3 MHz.
b) Open-loop gain at second pole (
135°) 55 dB.
