Elimination of the external capacitors allows the designer to increase reliability, lower cost, and simplify design by lowering parts count. More important, there is almost zero drift with time. This eliminates production line adjustments, as well as periodic calibration. Notable electrical characteristics are low supply current (450µA, typical), single-supply operation (5V to 32V), low input offset voltage (7µV, typical), low noise (<5µVP-P, typical, for a 10Hz bandwidth), and fast recovery from saturation without the use of external clamp circuitry.
