DESCRIPTION
The OPA337 and OPA338 series rail-to-rail output CMOS
operational amplifiers are designed for low cost and
miniature applications. Packaged in the SOT23-8, the
OPA2337EA and OPA2338EA are Texas Instruments’
smallest dual op amps. At 1/4 the size of a conventional
SO-8 surface-mount, they are ideal for space-sensitive
applications.
Utilizing advanced CMOS technology, the OPA337 and
OPA338 op amps provide 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 common-mode voltage range
includes ground—ideal for single-supply operation.
The OPA337 series is unity-gain stable. The OPA338 series
is optimized for gains greater than or equal to 5. 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.
