DESCRIPTION
The OPA241 and OPA251 are specifically designed
for battery powered, portable applications. In addition
to very low power consumption (24
μ
A), these ampli-
fiers feature low offset voltage, rail-to-rail output
swing, high common-mode rejection, and high open-
loop gain.
The OPA241 is optimized for operation at low power
supply voltage while the OPA251 is optimized for
high power supplies. Both op amps 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.
The OPA241 and OPA251 are unity-gain stable and
can drive large capacitive loads. Special design con-
siderations 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 (
±
250
μ
V max) is so low, user adjust-
ment is usually not required. However, external trim
pins are provided for special applications.
The OPA241 and OPA251 are available in standard
8-pin DIP and SO-8 surface-mount packages. Both
are fully specified from –40
°
C to +85
°
C and operate
from –55
°
C to +125
°
C.
