Applications Information
GENERAL INFORMATION
Low supply current, wide bandwidth, input common mode
voltage range that includes both rails, “rail-to-rail” output,
good capacitive load driving ability, wide supply voltage (1.8V
to 32V) and low distortion all make the LM7301 ideal for many
diverse applications.
The high common-mode rejection ratio and full rail-to-rail in-
put range provides precision performance when operated in
non-inverting applications where the common-mode error is
added directly to the other system errors.
CAPACITIVE LOAD DRIVING
The LM7301 has the ability to drive large capacitive loads. For
example, 1000 pF only reduces the phase margin to about 25
degrees.
TRANSIENT RESPONSE
The LM7301 offers a very clean, well-behaved transient re-
sponse. Figures 1, 2, 3, 4, 5, 6 show the response when
operated at gains of +1 and −1 when handling both small and
large signals. The large phase margin, typically 70 to 80 de-
grees, assures clean and symmetrical response. In the large
signal scope photos,
is set to 4.8V. Note that the output goes to within 100 mV of
the supplies cleanly and without overshoot. In the small signal
samples, the response is clean, with only slight overshoot
when used as a follower.
