Product Details

describe:

The OPA182 , OPA2182, and OPA4182 (OPAx182) are the AD5173BRM50 precision operational amplifiers in ultralow noise, fast settling, zero-drift devices that provide rail-to-rail output operation with a unique MUX-friendly architecture and controlled startup system. These features and excellent AC performance, combined with an offset voltage of only 0.45 μV and a temperature drift of 0.003 μV/°C, make the OPAx182 an excellent choice for data acquisition, battery testing, analog input modules, scales, and any other system requirements High DC accuracy and low noise.

The MUX-friendly input architecture prevents inrush currents when large input differential voltages are applied, improving stable performance in multi-channel systems. Additionally, the controlled start-up system rejects any inrush current when the power rails rise, while providing robust ESD protection during shipping, handling and assembly.

The device is specified over a temperature range of –40°C to +125°C.
