For best AC results (for example, fast settling time) use a ground plane, short lead lengths and RF quality bypass capacitors (0.01μF to 0.1μF) in parallel with low ESR bypass capaci- tors (1μF to 10μF tantalum). For best DC performance, use “star” grounding techniques, equalize input trace lengths and minimize leakage (e.g., 1.5GΩ of leakage between an input and a 15V supply will generate 10nA—equal to the maximum IB– specification). Board leakage can be minimized by encircling the input circuitry with a guard ring operated at a potential close to that of the inputs: for inverting configurations tie the ring to ground, in noninverting connections tie the ring to the inverting input (note the input capacitance will increase which may require a compensating capacitor as discussed below). Microvolt level error voltages can also be generated in the external circuitry. Thermocouple effects caused by temperature gradients across dissimilar metals at the contacts to the inputs can exceed the inherent drift of APPLICATIONS INFORMATION VS = ±15V 1469 G37 VS = ±15V 1469 G38 VS = ±15V 1469 G39 VS = ±15V 1469 G40 |
