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.
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
