LM6132/34 Application Hints
The LM6132 brings a new level of ease of use to opamp sys-
tem design.
With greater than rail-to-rail input voltage range concern
over exceeding the common-mode voltage range is elimi-
nated.
Rail-to-rail output swing provides the maximum possible dy-
namic range at the output. This is particularly important
when operating on low supply voltages.
The high gain-bandwidth with low supply current opens new
battery powered applications, where high power consump-
tion, previously reduced battery life to unacceptable levels.

To take advantage of these features, some ideas should be
kept in mind.
ENHANCED SLEW RATE
Unlike most bipolar opamps, the unique phase reversal
prevention/speed-up circuit in the input stage eliminates
phase reversal and allows the slew rate to be very much a
function of the input signal amplitude.
Figure 2 shows how excess input signal is routed around the
input collector-base junctions directly to the current mirrors.
The LM6132/34 input stage converts the input voltage
change to a current change. This current change drives the
current mirrors through the collectors of Q1–Q2, Q3–Q4
when the input levels are normal.
