Biasing & Decoupling Op Amps in Single Supply Applications - AN-581 Analog Devices Application Notes (app note added 2/06)

Chip Logic probe - This logic probe uses a single CMOS IC and shows three logic conditions, High, Low and Pulsing. In addition if the probe input is neither hi or low (the high impedance state of tri-output logic ic's) then no LED's will light. Power from the logic probe is taken from the logic circui....
