DESCRIPTION
The OPA241 series and OPA251 series are specifically
designed for battery powered, portable applications. In addi-
tion to very low power consumption (25
μ
A), these amplifi-
ers feature low offset voltage, rail-to-rail output swing, high
common-mode rejection, and high open-loop gain.
The OPA241 series is optimized for operation at low power
supply voltage while the OPA251 series is optimized for
high power supplies. Both can operate from either single
(+2.7V to +36V) or dual supplies (
±
1.35V to
±
18V). The
input common-mode voltage range extends 200mV below
the negative supply—ideal for single-supply applications.
They are unity-gain stable and can drive large capacitive
loads. Special design considerations assure that these prod-
ucts are easy to use. High performance is maintained as the
amplifiers swing to their specified limits. Because the initial
offset voltage (
±
250
μ
V max) is so low, user adjustment is
usually not required. However, external trim pins are pro-
vided for special applications (single versions only).
The OPA241 and OPA251 (single versions) are available
in standard 8-pin DIP and SO-8 surface-mount packages.
The OPA2241 and OPA2251 (dual versions) come in 8-pin
DIP and SO-8 surface-mount packages. The OPA4241 and
OPA4251 (quad versions) are available in 14-pin DIP and
SO-14 surface-mount packages. All are fully specified
from –40
°
C to +85
°
C and operate from –55
°
C to +125
°
C.
