List of linear integrated circuits

The following is a list of linear integrated circuits. Many were among the first analog integrated circuits commercially produced; some were groundbreaking innovations, and many are still being used.^[1]

Part number	Predecessor	Obsolete?	Description
555 timer IC		No	Timer, pulse generation, and oscillator applications.
78xx		No	Family of self-contained fixed linear voltage regulator integrated circuits.
Current conveyor			Electronic amplifier with unity gain. Three versions of generations of the idealised device, CCI, CCII and CCIII.[2]
Low-dropout regulator (LDO)			DC linear voltage regulator that can regulate the output voltage even when the supply voltage is very close to the output voltage.[3]
Hitachi HA12043		Yes	CX noise reduction system for phonograph records in the 1980s.
Hitachi HA12044		Yes	CX noise reduction system for phonograph records in the 1980s.
MK484			Fully functional AM radio detector on a chip. Constructed in a TO-92 case.[4][5]
NE612			Oscillator and a mixer. Used in ham radio applications.[6]
Operational amplifier			DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.[7]
Telefunken U401B		Yes	High quality High Com analogue compander for audio in the 1970s.
