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 applies 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.
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 over driven or overloaded.
Single (OPA277) and dual (OPA2277) versions are available in DIP-8,SO-8, and DFN-8(4mm x 4mm) packages.The quad(OPA4277) comes in DIP-14 and SO-14 surface-mount packages.All are fully specified from -40℃ to +85℃ and operate from -55℃ to +125℃.

The OPA2277UA integrated circuit is an excellent choice for any project requiring a low-noise operational amplifier. It has a wide range of features and is easy to use. The low noise and low power consumption make it an ideal choice for many applications. The circuit is also very reliable and has a long life expectancy. I highly recommend the OPA2277UA for any project requiring an operational ampl
