OPA2277TDD1

高精度运算放大器 HIGH-PRECISION OPERATIONAL AMPLIFIER

DESCRIPON

The OPA2277 precision op amp replaces the industry standard OP-177. It offers 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.

The OPA2277 op amp operates from ±2V to ±18V supplies with excellent performance. Unlike most op amps which are specified at only one supply voltage, the OPA2277 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.

The OPA2277 op amp is easy to use and free from phase inversion and overload problems found in some other op amps. It is stable in unity gain and provides excellent dynamic behavior over a wide range of load conditions. The dual version features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded.
