Filin kasuwar guntu na analog na duniya ya kusan dalar Amurka biliyan 60.Kasuwar duniya na da'irori da aka haɗa ita ce dala biliyan 340.2, tare da da'irar analog ɗin da ke lissafin kashi 15%.Daga cikin da'irori na analog, kasuwar siginar siginar ita ce dala biliyan 14.3, kuma kasuwar sarrafa wutar lantarki ita ce dala biliyan 21.6.An fara da haɗin op-amp na farko wanda ya bayyana a cikin 1968, ta 2018, kwakwalwan kwamfuta na analog sun zama masana'antar duniya ta kusan dalar Amurka biliyan 60.

A halin yanzu, manyan kamfanonin guntu na analog guda 10 suna riƙe fiye da rabin kason kasuwa.A cikin 2018, manyan kamfanonin guntu analog na 10 sune Texas Instruments (TI), Adenor (ADI), Infineon, Skyworks, ST Microelectronics, NXP, Maxim, Kan Semiconductor, da Kan Semiconductor.Maxim, On Semi, Microchip, da Renesa.

Daga cikin su, Texas Instruments ya ƙware a sarrafa wutar lantarki kuma shine jagora a wannan fanni;ADI ya fara ne da amplifiers masu aiki kuma shine jagora a cikin masu canza bayanai, tare da babban kasuwa a cikin op-amps da sarrafa wutar lantarki.An fitar da Infineon daga rukunin Siemens kuma kamfani ne mai zaman kansa da aka jera.Kamfanonin guntu na analog masu daraja na yanzu, waɗanda aka kafa a farkon 1960s da zinare na 1990 lokacin da aka haifi da'irori masu haɗaka, sun girma tare da masana'antar da'ira, gami da jagora na yanzu Texas Instruments (1930), tsohon shugaban National Semiconductor.
