Power Operational Amplifiers
FEATURES

DESCRIPTION

The PA16 and PA16A are wideband, high output current operational amplifiers designed to drive resistive,
inductive and capacitive loads. Their complementary
“collector output” stage can swing close to the supply
rails and is protected against inductive kickback. For
optimum linearity, the output stage is biased for class
A/B operation. The safe operating area (SOA) can be
observed for all operating conditions by selection of
user programmable, current limiting resistors (down to
10mA). Both amplifiers are internally compensated but
are not recommended for use as unity gain followers.
For continuous operation under load, mounting on a
heatsink of proper rating is recommended.
These hybrid integrated circuits utilize thick film (cermet) resistors, ceramic capacitors and semiconductor
chips to maximize reliability, minimize size and give
top performance. Ultrasonically bonded aluminum
wires provide reliable interconnections at all operating
temperatures. The Power SIP package is electrically
isolated.
