XL177GS

The XL177 op amp offers one of the highest accuracy performances currently available on the market. At room temperature, its maximum offset voltage is only 50 μV. The XL177's ultralow offset voltage combined with an outstanding offset voltage drift of 0.5 μV/°C maximum eliminates the need for external offset voltage adjustment and improves system accuracy over the temperature range. The XL177 features an open-loop gain of 12 V/μV, which remains stable across the entire ±10 V output range. A minimum common-mode rejection ratio of 105 dB, a minimum power supply rejection ratio of 100 dB, and a maximum supply current of 3 mA are just a few examples of this op amp's exceptional performance. The XL177's outstanding combination of specifications ensures precise performance in high closed-loop gain applications. This low-noise, bipolar-input op amp also serves as a cost-effective alternative to chopper-stabilized amplifiers. The XL177 delivers chopper-type performance while avoiding the typical drawbacks of high noise, low-frequency chopper spikes, large physical size, limited common-mode input voltage range, and bulky external storage capacitors. The XL177 operates over an extended industrial temperature range of -40°C to +85°C. The product is available in an 8-pin PDIP package as well as a space-saving 8-pin SOP package.
