OPERATIONAL AMPLIFIERS  
DESCRIPTION  
OPA241 Family optimized for +5V supply.  
OPA251 Family optimized for ±15V supply.  
The OPA241 series and OPA251 series are specifically  
designed for battery powered, portable applications. In addi-  
tion to very low power consumption (25µA), these amplifi-  
ers feature low offset voltage, rail-to-rail output swing, high  
common-mode rejection, and high open-loop gain.  
FEATURES  
● MicroPOWER: IQ = 25µA  
● SINGLE-SUPPLY OPERATION  
● RAIL-TO-RAIL OUTPUT (within 50mV)  
● WIDE SUPPLY RANGE  
Single Supply: +2.7V to +36V  
Dual Supply: ±1.35V to ±18V  
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 (±250µV max) is so low, user adjustment is  
usually not required. However, external trim pins are pro-  
vided for special applications (single versions only).  
● LOW OFFSET VOLTAGE: ±250µV max  
● HIGH COMMON-MODE REJECTION: 124dB  
● HIGH OPEN-LOOP GAIN: 128dB  
● SINGLE, DUAL, AND QUAD  
APPLICATIONS  
● BATTERY OPERATED INSTRUMENTS  
● PORTABLE DEVICES  
● MEDICAL INSTRUMENTS  
● TEST EQUIPMENT  
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.
