Details

Featuring enhanced noise performance, wider output voltage swing, and increased speed with reduced quiescent current, the OPA2277U/2K5 is a precision operational amplifier designed to exceed the capabilities of the industry standard OP-177. Its ultra-low offset voltage and drift, low bias current, high common-mode rejection, and high power supply rejection make it a standout choice for applications requiring high precision and reliability. With an operating range from ±2-V to ±18-V supplies, the OPA2277U/2K5 provides consistent and exceptional performance across a variety of real-world scenarios. Thanks to its low initial offset voltage, user adjustment is typically not necessary, although the single version (OPA277) offers external trim pins for specialized applications. Additionally, this amplifier is free from phase inversion and overload issues commonly found in other op amps, making it easy to use and highly reliable. Its unity-gain stability and excellent dynamic behavior over a wide range of load conditions ensure dependable performance. The dual and quad versions feature independent circuitry, minimizing crosstalk and interaction, even under overdriven or overloaded conditions
