{{Short description|Integrated device containing configurable analog blocks and interconnects between these blocks}}
A '''field-programmable analog array''' ('''FPAA''') is an [[Integrated circuit|integrated circuit device]] containing computational [[Analog signal|analog]] blocks (CAB)<ref>{{cite journalbook |last1=Hall |first1=Tyson |last2=Twigg |first2=Christopher |last3=Hassler |first3=Paul |last4=Anderson |first4=David |title=APPLICATION2004 PERFORMANCEIEEE OFInternational ELEMENTSSymposium INon ACircuits FLOATING–GATEand FPAASystems (IEEE Cat.

Unlike their [[Digital signal|digital]] cousin, the [[Field-programmable gate array|FPGA]], the devices tend to be more application driven than general purpose as they may be [[Current-mode logic|current mode]] or voltage mode devices. For voltage mode devices, each block usually contains an [[operational amplifier]] in combination with programmable configuration of passive components. The blocks can, for example, act as [[Analog adder|summers]] or [[integrator]]s.
FPAAs usually operate in one of two modes: [[Discrete time and continuous time|''continuous time'' and ''discrete time'']].
