Differentiate single power supply and dual power supply type?

Latest Updated:12/01/2011


What are the differences between single power supply type and dual power supply type operational amplifiers?


There is no strict difference. Generally, however, the range of the common mode input voltage range differs. Products that operate with an input up to the same voltage as V- are categorized as operational amplifiers for a single power supply. The conventional dual power supply type is a product that cannot be used in a range between V- and about 1.5 V.
