OPA241 Family optimized for +5V supply. DESCRIPTION OPA251 Family optimized for В±15V supply. The OPA241 series and OPA251 series are specifically
designed for battery powered, portable applications. In addition to very low power consumption (25ВµA), 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 (В±1.35V to В±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 (В±250ВµV 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 …
