Sag Correction
In a 5V application, the MAX4090 can use the sag con-
figuration if an AC-coupled output video signal is
required. Sag correction refers to the low-frequency
compensation for the highpass filter formed by the
150
Ω load and the output capacitor. In video applica-
tions, the cutoff frequency must be low enough to pass
the vertical sync interval to avoid field tilt. This cutoff
frequency should be less than 5Hz, and the coupling
capacitor must be very large in normal configuration,
typically > 220F. In sag configuration, the MAX4090
eliminates the need for large coupling capacitors, and
instead requires two 22F capacitors (Figure 6) to
reach the same performance as the large capacitor.
Bench experiments show that increasing the output
coupling capacitor C5 beyond 47F does not improve
the performance. If the supply voltage is less than 4.5V,
the sag correction is not recommended for the
MAX4090.
