Zero-drift amplifiers have the lowest input offset voltage (Vos) and offset voltage drift of any operational amplifier (op amp) topology. Compared to best-in-class precision low-input offset-voltage ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...
