A Single-Supply Op-Amp Circuit Collection
mil.ufl.eduThere have been many excellent collections of op-amp circuits in the past, but all of them focus exclusively on split-supply circuits. Many times, the designer who has to operate a circuit from a single supply does not know how to do the conversion. Single-supply operation requires a little more care than split-supply circuits. The designer should

The basic circuits for op-amp’s are 1-Comparators 2-Summing Amplifiers 3-Integrators and Differentiators. 13.1: Comparators A comparator is a specialized nonlinear op-amp circuit that compares between two input voltages and produces an output state that indicates which one is greater. Comparators
Op Amps for MEMS Microphone Preamp Circuits
www.analog.comThis application note covers some of the key op amp specifi-cations to consider in a preamp design, show s a few basic circuits, and provides a table of Analog Devices, Inc., op amps that may be appropriate for a preamp design. The . ADMP504 MEMS micro-phone is used as an example in this application note to describe different design choices.
