The high common-mode input voltage range and
the absence of latch-up make the amplifier ideal
for voltage-follower applications. The device is
short-circuit protected and the internal frequency
compensation ensures stability without external
components. A low value potentiometer may be
connected between the offset null inputs to null
out the offset voltage as shown in Figure 2.
