... Direct access arrangement Office automation GENERAL DESCRIPTION The OP162 (single), OP262 (dual), and OP462 (quad) rail-to- rail 15 MHz amplifiers feature the extra speed new designs require, with the benefits of precision and low power operation. With their incredibly low offset voltage of 45 µV (typical) and low noise, they are perfectly suited for precision filter applica- tions and instrumentation. The low supply current of 500 µ ...

... OP162 2 Figure 34. Offset Adjustment Schematic RAIL-TO-RAIL OUTPUT The OP162/OP262/OP462 have a wide output voltage range that extends to within each supply rail with a load current of 5 mA. Decreasing the load current extends the output voltage range even closer to the supply rails. The common-mode input range extends from ground to within the positive supply ...
