FIGURE 33. IMPROVED DECOUPLING/CURRENT LIMITING
Chip capacitors produce the best results due to ease of
placement next to the op amp and they have negligible lead
inductance. If leaded capacitors are used, the leads should
be kept as short as possible to minimize lead inductance.
Figures 32 and 33 illustrate two different decoupling
schemes. Figure 33 improves the PSRR because the
resistor and capacitors create low pass filters. Note that the
supply current will create a voltage drop across the resistor.
Saturation Recovery
When an op amp is over driven output devices can saturate
and sometimes take a long time to recover. By clamping the
input to safe levels, output saturation can be avoided. If
output saturation cannot be avoided, the recovery time from
25% over-drive is 20ns and 30ns from 50% over-drive.
Thermal Management
The HFA-0001 can sink and source a large amount of
current making it very useful in many applications. Care
must be taken not to exceed the power handling capability of
the part to insure proper performance and maintain high
reliability. The following graph shows the maximum power
handling capability of the HFA-0001 without exceeding the
maximum allowable junction temperature of +175
o
C. The
curves also show the improved power handling capability
when heatsinks are used based on AVVID heatsink #5801B
for the 8 lead Plastic DIP and IERC heatsink #PEP50AB for
the 14 lead Sidebraze DIP. These curves are based on
natural convection. Forced air will greatly improve the power
dissipation capabilities of a heatsink.
