Cir- cuit layout should be arranged to keep all lead lengths as short as possible and the output separated from the inputs. The values of the feedback and source impedances should be kept small to reduce the effect of stray capacitance at the in- puts. The power supplies must be bypassed to ground at the supply teads of the amplifier with low inductance capacitors. Capacitive loading must be kept to minimum, or the amplifier must be isolated as shown in the applications.
