Warning The OPA569 is a low-cost, high-current, operational amplifier
designed for driving a wide variety of loads while operating on
low-voltage supplies. It operates from either single or dual
supplies for design flexibility and has rail-to-rail swing on the
input and output. Typical output swing is within 150mV of the
supply rails, with output current of 2A. Output swing closer to
the rails is achievable with lighter loads. в—Џ LOW SUPPLY VOLTAGE OPERATION: 2.7V to 5.5V
в—Џ SHUTDOWN FUNCTION WITH OUTPUT DISABLE
в—Џ SMALL POWER PACKAGE: SO-20 PowerPADв„ў The OPA569 is unity-gain stable, has low dc errors, is easy
to use, and free from the phase inversion problems found in
some power amplifiers. High performance is maintained at
voltage swings near the output rails. APPLICATIONS The OPA569 provides an accurate user-selected current …
