DESCRIPTION
The TPA02 and TPA02A are fast, high output
current operational amplifiers designed to drive
resistive or reactive loads. The common collector
output stage swings close to the supply rails and
is protected against inductive kickback by diodes
to the rails. The safe operating area (SOA) can
be selected by external current limiting resistors.
The output stage is biased for class A/B operation
to achieve low distortion. The amplifiers are
internally compensated but are not suitable for
use as unity gain followers.
POWER DELIVERY EFFICIENCY AND LOW DISTORTION
Due to the common collector output stage, these
amplifiers can deliver power with high efficiency
particularly for low voltage applications. In the
example application below the TPA02 delivers
power with high efficiency and due to the high
power bandwidth also low distortion.
