DESCRIPTION
The OPA244 (single), OPA2244 (dual), and OPA4244 (quad)
op amps are designed for very low quiescent current
(50碌A/channel), yet achieve excellent bandwidth. Ideal for
battery powered and portable instrumentation, all versions are
offered in micro packages for space-limited applications.
The dual and quad versions feature completely independent
circuitry for lowest crosstalk and freedom from interaction, even
when overdriven or overloaded.
The OPA244 series is easy to use and free from phase
inversion and overload problems found in some other op amps.
These amplifiers are stable in unity gain and excellent perfor-
mance is maintained as they swing to their specified limits.
They can be operated from single (+2.2V to +36V) or dual
supplies (鹵1.1V to
鹵18V).
The input common-mode voltage
range includes ground鈥攊deal for many single supply applica-
tions. All versions have similar performance. However, there
are some differences, such as common-mode rejection. All
versions are interchangeable in most applications.
All versions are offered in miniature, surface-mount packages.
OPA244 (single version) comes in the tiny 5-lead SOT-23-5
surface mount, SO-8 surface mount, and 8-pin DIP. OPA2244
(dual version) is available in the MSOP-8 surface mount,
SO-8 surface-mount, and 8-pin DIP. The OPA4244 (quad)
comes in the TSSOP-14 surface mount. They are fully specified
from 鈥?0擄C to +85擄C and operate from 鈥?5擄C to +125擄C.
A SPICE Macromodel is available for design analysis.
