Therefore, care must always be exercised in layingout signal paths by not placing the trimmer, or the nulling The OP-61combines highspeed witha levelofprecision and noise performance normally only found with slower amplifiers. Data acquisition and instrumentation technology has progressed to where dynamic accuracy and high resolution are both maintained to a very highlevel.The OP-61 was specifically designed to meet the stringent requirements of these systems. inputlines.directlyadjacentto highfrequency signal lines. .V 0.1~F Signal-to-noise ratio degrades as input referred noise or bandwidth increases. The OP-61 has a very wide bandwidth, but its input noise is only 3nV/..;RZ. This makes the total noise gener- I---:L ated over its closed-loop bandwidth considerably less than previously available wideband operational amplifiers. The OP-61 provides stable operation in closed-loop gain configurations of 10 or more. Large load capacitances should be Vas ADJUST decoupled with a resistor placed inside the feedback loop (see Driving Large Capacitive Loads). OFFSET VOLTAGE ADJUSTMENT Offset Yoltage can be adjusted by a potentiometer of 10ka to 100kil resistance. This potentiometer should be connected between pins 1and 5 with the wiper connected directly to the OP-61 V+ pin (see Figure 1). By connecting this line directly to the op amp V+ terminal, common impedance paths shared by both return currents and the null inputs willbe avoided. Nulling inputs -y POTENTIOMETERSRANGINGFROM 101
