XL277UA

The XL277 series outperforms the XL177 series in noise, output voltage swing, and speed, while reducing quiescent current by half. Key features include ultra-low offset voltage and drift, low bias current, high common-mode rejection ratio, and high power supply rejection ratio. The series operates over a supply voltage range of ±2V to ±18V with excellent performance. Unlike most op-amps specified at only a single supply voltage, the XL277 series is characterized for real-world applications, with a single set of specifications covering the entire supply range from ±5V (10V) to ±15V (30V). High performance is maintained even when the output swings to the specified limits. The extremely low initial offset voltage (maximum ±40μV) typically eliminates the need for user trimming. The XL277 series is easy to use, free from the phase reversal and overload issues found in some other op-amps. The device is unity-gain stable and delivers excellent dynamic performance under a wide range of load conditions.
