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 m A (typical) and are stable with capacitive loads to 10 n F. Applications that benefit from the high output current of the OP179/OP279 include driving headphones, displays, transformers and power transistors. The powerful output is bined with a unique input stage that maintains very low distortion with wide mon-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.
