Instrumentation shield line driver
This circuit uses an ELH0033 fast buffer amplifier to form an instrumentation shield / line driver. Power supply bypassing is necessary to prevent oscillation with the ELH0033. Low inductance disc capacitors with the shortest practical lead lengths must be connected from each supply lead to a ground plane. Capacitors should be one or two 0.1uF in parallel; adding a 4.7uF solid tantalum capacitor will help in troublesome instances. RF / video printed circuit board layout rules should be followed when using the ELH0033 since it will provide power gain to frequencies over 100MHz. Power supply voltages can be up to +/-15v.
