to learn more about on semiconductor, please visit our website at www.onsemi.com please note: as part of the fairchild semiconductor integration, some of the fairchild orderable part numbers will need to change in order to meet on semiconductors system requirements. since the on semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the fairchild part numbers will be changed to a dash (-). this document may contain device numbers with an underscore (_). please check the on semiconductor website to verify the updated device numbers. the most current and up-to-date ordering information can be found at www.onsemi.com . please email any questions regarding the system integration to fairchild_questions@onsemi.com . is now part of on semiconductor and the on semiconductor logo are trademarks of semico nductor components industries, llc dba on semiconductor or its subsid iaries in the united states and/or other countries. on semiconductor ow ns the rights to a number of patents, trademarks, copyrights, trade secrets, and other intellec tual property. a listing of on semiconductor?s product/patent cover age may be accessed at www.onsemi.com/site/pdf/patent-marking.pdf . on semiconductor reserves the right to make changes without further notice to any products herein. on semicon ductor makes no warranty, representation or guarantee regarding the s uitability of its products for any particular purpose, nor does on semico nductor assume any liability arising out of the application or use of any product or circuit, and speci?ca lly disclaims any and all liability, including without limitation spe cial, consequential or incidental damages. buyer is responsible for i ts products and applications using on semiconductor products, including compliance with all laws, regul ations and safety requirements or standards, regardless of any suppor t or applications information provided by on semiconductor. ?typica l? parameters which may be provided in on semiconductor data sheets and/or speci?cations can and do vary in diffe rent applications and actual performance may vary over time. all operat ing parameters, including ?typicals? must be validated for each custo mer application by customer?s technical experts. on semiconductor does not convey any license und er its patent rights nor the rights of others. on semiconductor products a re not designed, intended, or authorized for use as a critical compone nt in life support systems or any fda class 3 medical devices or medical devices with a same or similar classi?ca tion in a foreign jurisdiction or any devices intended for implantation i n the human body. should buyer purchase or use on semiconductor products fo r any such unintended or unauthorized application, buyer shall indemnify and hold on semico nductor and its of?cers, employees, subsidiaries, af?liates, and di stributors harmless against all claims, costs, damages, and expense s, and reasonable attorney fees arising out of, directly or indirectly, any claim of personal injury or death associa ted with such unintended or unauthorized use, even if such claim alleges th at on semiconductor was negligent regarding the design or manufacture o f the part. on semiconductor is an equal opportunity/af?rmative action employer. this literatu re is subject to all applicable copyright laws and is not for resale in any manne r.
?2011 fairchild semiconductor corporation www.fairchildsemi.com rev. 1.0.4 features internally frequency compensated for unity gain large dc voltage gain: 100db wide power supply range: ka258/ka258a, KA358/KA358a: 3v ~ 32v (or 1.5v~ 16v) ka2904 : 3v~26v (or 1.5v ~ 13v) input common mode voltage range includes ground large output voltage swing: 0v dc to vcc - 1.5v dc power drain suitable for battery operation. description the ka258 series consist of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. application areas include transducer amplifier, dc gain blocks and all the conventional op-amp circuits which now can be eas ily implemented in single power supply systems. 8-dip 8-soic 1 1 internal block diagram - + + - 12 3 45 6 7 8 v cc out2 in2 (-) in2 (+) out1 in1 (-) in1 (+) gnd k a2 5 8 /k a2 5 8 a, k a3 5 8 /k a3 5 8 a, k a2 9 0 4 dua l ope rat iona l am plifie r
