TYPICAL APPLICATION The TDA9511 consists of : - A differential amplifier with active load, - A DMOS output buffer, - Abandgapvoltage reference(Pin 3 forfiltering only). 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. Figure 2 : Typical Evaluation Schematic

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/20k = 2.95W
