Hmmmmmm.)

At 0.97 nV/rHz it is currently the lowest noise integrated
op-amp made. It is designed for use with 1K input impedance's
or below. As long as you can use 1K resistors or less
this baby is great for $4.

For 10K to 100K impedance range, Analog Devices
recommends the AD711 for better noise performance.
