High Precision  
OPERATIONAL AMPLIFIERS  
FEATURES  
● ULTRA LOW OFFSET VOLTAGE: 10µV  
● ULTRA LOW DRIFT: ±0.1µV/°C  
● HIGH OPEN-LOOP GAIN: 134dB  
● HIGH COMMON-MODE REJECTION: 140dB  
● HIGH POWER SUPPLY REJECTION: 130dB  
● LOW BIAS CURRENT: 1nA max  
DESCRIPTION  
The OPA277 series precision op amps replace the industry  
standard OP-177. They offer improved noise, wider output  
voltage swing, and are twice as fast with half the quiescent  
current. Features include ultra low offset voltage and drift, low  
bias current, high common-mode rejection, and high power  
supply rejection. Single, dual, and quad versions have identical  
specifications for maximum design flexibility.  
OPA277 series op amps operate from ±2V to ±18V supplies  
with excellent performance. Unlike most op amps which  
are specified at only one supply voltage, the OPA277 series  
is specified for real-world applications; a single limit ap-  
plies over the ±5V to ±15V supply range. High performance  
is maintained as the amplifiers swing to their specified limits.  
Because the initial offset voltage (±20µV max) is so low, user  
adjustment is usually not required. However, the single version  
(OPA277) provides external trim pins for special applications.  
● WIDE SUPPLY RANGE: ±2V to ±18V  
● LOW QUIESCENT CURRENT: 800µA/amp  
● SINGLE, DUAL, AND QUAD VERSIONS  
● REPLACES OP-07, OP-77, OP-177  
APPLICATIONS  
● TRANSDUCER AMPLIFIER  
● BRIDGE AMPLIFIER  
OPA277 op amps are easy to use and free from phase inversion  
and overload problems found in some other op amps. They are  
stable in unity gain and provide excellent dynamic behavior  
over a wide range of load conditions. Dual and quad versions  
feature completely independent circuitry for lowest crosstalk  
and freedom from interaction, even when overdriven or over-  
loaded.  
● TEMPERATURE MEASUREMENTS  
● STRAIN GAGE AMPLIFIER  
● PRECISION INTEGRATOR  
● BATTERY POWERED INSTRUMENTS  
● TEST EQUIPMENT  
Single (OPA277) and dual (OPA2277) versions are available  
in 8-pin DIP and SO-8 surface-mount packages. The quad  
(OPA4277) comes 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.
