OP179/OP279,pdf datasheet (Cur

The OP179 and OP279 are rail-to-rail, high output current,
single-supply amplifiers. They are designed for low voltage
applications that require either current or capacitive load drive
capability. The OP179/OP279 can sink and source currents of
±60 mA (typical) and are stable with capacitive loads to 10 nF.
Applications that benefit from the high output current of the
OP179/OP279 include driving headphones, displays, transformers
and power transistors. The powerful output is combined with a
unique input stage that maintains very low distortion with wide
common-mode range, even in single supply designs.
The OP179/OP279 can be used as a buffer to provide much
greater drive capability than can usually be provided by CMOS
outputs. CMOS ASICs and DAC often have outputs that can
swing to both the positive supply and ground, but cannot drive
more than a few milliamps.
Bandwidth is typically 5 MHz and the slew rate is 3 V/μs, making
these amplifiers well suited for single supply applications that
require audio bandwidths when used in high gain configurations.
Operation is guaranteed from voltages as low as 4.5 V, up to 12 V.
