GENERAL DESCRIPTION

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, transform-

ers 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.

Very good audio performance can be attained when using the

OP179/OP279 in 5 volt systems. THD is below 0.01% with a

600 Ω load, and noise is a respectable 21 nV/√Hz. Supply current

is less than 3.5 mA per amplifier.

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.

The single OP179 is available in the 5-lead SOT-23-5 package.

It is specified over the industrial (–40°C to +85°C) tempera-

ture range.

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.

The OP279 is available in 8-lead TSSOP and SO-8 surface

mount packages. They are specified over the industrial (–40°C

to +85°C) temperature range.
