Application Notes:
(Continued)
Other Application Hints:
The use of supply decoupling is mandatory in most applica-
tions. As with most relatively high speed/high output current
OpAmps, best results are achieved when each supply line is
decoupled with two capacitors; a small value ceramic ca-
pacitor (
～
0.01μF) placed very close to the supply lead in ad-
dition to a large value Tantalum or Aluminum (
>
4.7μF). The
large capacitor can be shared by more than one device if
necessary. The small ceramic capacitor maintains low sup-
ply impedance at high frequencies while the large capacitor
will act as the charge
″
bucket
″
for fast load current spikes at
the Op Amp output. The combination of these capacitors will
provide supply decoupling and will help keep the OpAmp os-
cillation free under any load.
LM8261 Advantages:
Compared to other Rail-to-Rail Input/Output devices, the
LM8261 offers several advantages such as:
Improved cross over distortion.
Nearly constant supply current throughout the output
voltage swing range and close to either rail.
Consistent stability performance for all input/output volt-
age and current conditions.
Nearly constant Unity gain frequency (f
) and Phase Mar-
gin (Phi
m
) for all operating supplies and load conditions.
No output phase reversal under input overload condition.
