OPAx277 Precision Operational Amplifiers

Texas Instruments OPAx277 Precision Operational Amplifiers are precision operational amplifiers that replace the industry standard OP-177. It offers improved noise, wider output voltage swing, and is 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. The OPAx277 operates from ±2 to ±18V supplies with excellent performance. The OPAx277 precision operational amplifier is specified for real-world applications with a single limit over the ±5 to ±15V supply range. The OPAx227 is easy to use and free from phase inversion and overload problems in some operational amplifiers. These devices are stable in unity gain and provide excellent dynamic behavior over various load conditions. The OPA4277-EP devices have gold bond wires, a temperature range of –55 to +105°C, and an SnPb lead finish.
