The AD8052LV is a single supply, general purpose, volt-
age-feedback amplifier fabricated on a complementary
bipolar process using a patent pending topography. They
feature a rail-to-rail output stage and is unity gain stable.
Both gain bandwidth and slew rate are insensitive to tem-
perature.

will not cause phase reversal. However, if the input volt-
age exceeds the rails by more than 0.5V, the input ESD
devices will begin to conduct. The output will stay at the
rail during this overdrive condition.

The design uses a Darlington output stage. The output
stage is short circuit protected and offers “soft” saturation
protection that improves recovery time.

Figures 1, 2, and 3 illustrate typical circuit configurations for
non-inverting, inverting, and unity gain topologies for dual
supply applications. They show the recommended bypass
capacitor values and overall closed loop gain equations.
Figure 4 shows the typical non-inverting gain circuit for
single supply applicaitons.
