Need information on fast, low-noise operational amplifiers. Requirements are
low noise (<4 nanovolt/sq.rt Hz), high slew rate (>500V/usec), wide bandwidth
(>80 Hz). We are currently using a National Semiconductor LH0032 (fast enough,
but need lower noise) and/or a Burr-Braun OPA637 (somewhat too slow at the
gains we are using, but better noise characteristics. Are there any better amps
