PC board lay-out The best performances are obtained with a carefully designed HF PC-Board, especially for the output and input capacitors. The feedback resistor RF must have a low parasitic capacitor (CF < 0.3pF). This parasitic capacitor CF must be compensated by a capacitor R3 (roughly 20 ⋅ CF) connected in parallel with the input resistor R1. The full bandwidth of the device is only obtained with well matched compensation otherwise the application will have either an integrator response with a low bandwidth or a differentiator response with too much ringing. A diode DP (see Figure 2) has to be connected for flashover protection. Power dissipation The power dissipation consists of a static part and a dynamic part. The static dissipation varies with the output voltage and the feedback resistor. The dynamic power dissipation increases with the pixel frequency. For a signal frequency of 40MHz and 40VPP output signal, the typical power dissipation is about 3.0W, for VDD = 110V. In first approximation, the dynamic dissipation is : PD = VDD * CLOAD * ∆VOUT * f and the total dissipation is : P = VDD * CLOAD * ∆VOUT * f + VDD * IDD _____ _____ VOUT + VCC * ICC - (VDD - VOUT) RFEEDBACK with f = pixel frequency P = 110V x 10pF x 40V x 40MHz + 110V x 7mA +12 x 20mA - 602V/20kΩ = 2.95W Figure 2 : Typical Evaluation Schematic CF RF VCC IN VDD R1 R3 DP 2 C3 1 RP 7 6 Recommended values : R1 = 1kΩ, R2 = 1.8kΩ, RF = 20kΩ, RP = 200Ω, C4 > 10nF, C3 = 10 to 12pF for CF # 0.5pF.
