A. 741 noise with circuit well-shielded from air
currents and RFI. (Note scale change.)
B. OP-07AH with circuit well-shielded from air
currents and RFI.
C. OPA27AJ with circuit well-shielded from air
currents and RFI. (Represents ultimate
OPA27 performance potential.)
D. OPA27 with circuit unshielded and exposed
to normal lab bench-top air currents.
(External thermoelectric potentials far
exceed OPA27 noise.)
E. OPA27 with heat sink and shield which
protects input leads from air currents.
Conditions same as (D).
