Differentiate single power supply and dual power supply type?

Latest Updated:12/01/2011

Question:

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

Answer:

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.
