The OPA4277-EP precision operational amplifier replaces 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 OPA4277-EP operates from ±2- to ±18-V supplies with excellent performance. Unlike most operational amplifiers which are specified at only one supply voltage, the OPA4277-EP precision operational amplifier is specified for real-world applications; a single limit applies over the ±5- to ±15-V supply range. High performance is maintained as the amplifier swings to the specified limits. Because the initial offset voltage (±20-µV max) is so low, user adjustment is usually not required.

The OPA4277-EP is easy to use and free from phase inversion and overload problems found in some operational amplifiers. It is stable in unity gain and provides excellent dynamic behavior over a wide range of load conditions. The OPA4277-EP features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
