The OPA241 series and OPA251 series are specifically
designed for battery powered, portable applications. In addition
to very low power consumption (25mA), these amplifiers
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 products
are easy to use. High performance is maintained as the
amplifiers swing to their specified limits. Because the initial
offset voltage (±250mV max) is so low, user adjustment is
usually not required. However, external trim pins are provided
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.
