The OP179 are rail-to-rail, high output current,single-supply amplifiers. They are designed for low voltageapplications that require either current or capacitive load drivecapability. The OP179 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 theOP179 include driving headphones, displays, transformers and power transistors. The powerful output is combined with aunique input stage that maintains very low distortion with widecommon-mode range, even in single supply designs.
The OP179 can be used as a buffer to provide muchgreater drive capability than can usually be provided by CMOSoutputs. CMOS ASICs and DAC often have outputs that canswing to both the positive supply and ground, but cannot drivemore than a few milliamps.
Bandwidth is typically 5 MHz and the slew rate is 3 V/µs, makingthese amplifiers well suited for single supply applications thatrequire audio bandwidths when used in high gain configurations.Operation is guaranteed from voltages as low as 4.5 V, up to 12 V.
Very good audio performance can be attained when using theOP179 in 5 volt systems. THD is below 0.01% with a600 Ω load, and noise is a respectable 21 nV/√Hz. Supply currentis less than 3.5 mA per amplifier.
The single OP179 is available in the 5-lead SOT-23-5 package.It is specified over the industrial (–40°C to +85°C) temperature range.
