... 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 ...

... OFFSET ADJUSTMENT Because the OP162/OP262/OP462 have an exceptionally low typical offset voltage, adjustment to correct offset voltage may not be needed. However, the OP162 has pinouts to attach a nulling resistor. Figure 34 shows how the OP162 offset voltage can be adjusted by connecting a potentiometer between Pin 1 and Pin 8, and connecting the wiper to V avoid accidentally connecting the wiper to V the device ...

Oscilloscope Photo of V CAPACITIVE LOAD DRIVE The OP162/OP262/OP462 are high speed, extremely accurate devices that tolerate some capacitive loading at their outputs 120 load capacitance increases, unity-gain bandwidth of an OPx62 device decreases. This also causes an increase in overshoot and settling time for the output. Figure 41 shows an example of this with the device configured for unity gain and driving a 10 kΩ ...

... PCB LAYOUT CONSIDERATIONS Because the OP162/OP262/OP462 can provide gains at high frequency, careful attention to board layout and component selection is recommended. As with any high speed application, a good ground plane is essential to achieve the optimum performance. This can significantly reduce the undesirable effects of ground loops and I × R losses by providing a low impedance reference point ...
