Rail-to-Rail High Output
Current Operational Amplifiers
OP179/OP279
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.
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/
μ
s, mak-
ing these amplifiers well suited for single supply applications
that require audio bandwidths when used in high gain configu-
rations. 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 21nV/
√
Hz
. Supply cur-
rent 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.
