FEATURES
● MicroSIZE PACKAGES:
DESCRIPTION
The OPA337 series and OPA338 series rail-to-rail output
CMOS operational amplifiers are designed for low cost and
miniature applications. Packaged in the new SOT-23-8, the
OPA2337EA and OPA2338EA are Burr-Brown’s smallest
dual op amps. At only 1/4 the size of a conventional SO-8
surface mount, they are ideal for space-sensitive applica-
tions.
SOT-23-5
SOT-23-8
● SINGLE-SUPPLY OPERATION
● RAIL-TO-RAIL OUTPUT SWING
● FET-INPUT: IB = 10pA max
● HIGH SPEED:
OPA337: 3MHz, 1.2V/µs (G = 1)
OPA338: 12.5MHz, 4.6V/µs (G = 5)
● OPERATION FROM 2.5V to 5.5V
● HIGH OPEN-LOOP GAIN: 120dB
● LOW QUIESCENT CURRENT: 525µA/amp
● SINGLE AND DUAL VERSIONS
Performance is not sacrificed for size. Utilizing advanced
CMOS technology, OPA337 and OPA338 op amps pro-
vide low bias current, high-speed operation, high open-
loop gain, and rail-to-rail output swing. They operate on a
single supply with operation as low as 2.5V while drawing
only 525µA quiescent current. In addition, the input com-
mon-mode voltage range includes ground—ideal for single-
supply operations.
The OPA337 series is unity-gain stable. The OPA338
series is optimized for gains greater than or equal to five.
They are easy to use and free from phase inversion and
overload problems found in some other op amps. Excellent
performance is maintained as the amplifiers swing to their
specified limits. The dual versions feature completely
independent circuitry for lowest crosstalk and freedom
from interaction, even when overdriven or overloaded.
APPLICATIONS
● BATTERY-POWERED INSTRUMENTS
● PHOTODIODE PRE-AMPS
● MEDICAL INSTRUMENTS
● TEST EQUIPMENT
● AUDIO SYSTEMS
● DRIVING ADCs
The OPA337 packages are the tiny SOT-23-5 surface
mount, SO-8 surface mount, and 8-pin DIP packages.
In addition to the miniature SOT-23-8 surface-mount
package, the OPA2337 is available in SO-8 surface-
mount and 8-pin DIP packages. The OPA338 packages
are the SOT-23-5 and SO-8 surface mounts. The OPA2338
packages are the SOT-23-8 and SO-8 surface mounts.
