GENERAL DESCRIPTION
8-Lead Plastic DIP (N-8)
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.

Very good audio performance can be attained when using the OP179/OP279 in +5 volt systems. THD is below 0.01% with a 600 load, and noise is a respectable 21 nV/Hz. Supply current is 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. The OP279 is available in 8-lead plastic DIP, TSSOP and SO-8 surface mount packages. They are specified over the industrial (­40°C to +85°C) temperature range.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP179/OP279 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
