Analog Devices has focused on he pulse-widh/heigh echnique and he vaiable ansconducance echnique o develop he muliply/divide funcion. These wo appoaches ae consideed complemenay and wee seleced because of hei inheen abiliy o povide a good balance beween pefomance and cos. PULSE-WDTH-HEGHT MODULATON PRECSON MULTPLERS (PWH) The pulse-widh-heigh modulaion echnique is capable of poducing muliplies of he highes pecision. Typical specificaions include accuacies fom 0.1 % o 0.25%, offse difs o 1OOllV / C, oupu noise of 50llV ms and bandwidhs o 100kHz. Muliplies in his goup should be used fo wide empeaue ange applicaions, fo analog c<nnpuing elemens, fo divides because of hei inheenly good dif, noise and low non-lineaiies, and, in geneal, fo exacing muliplie/divide applicaions whee wide dynamic signal swings ae anicipaed. Poducs in his goup include models 427. 424, and 425. MODEL 427 (HGH ACCURACY): Based on he highly successful Model 424, he 427K is inenally immed o specified accuacy and equies no exenal adjusmens fo muliplicaion. uses pulse-widh modulaion o obain accuacies o 0.2% (FS), offse difs as low as 2001lV/ C, and nonlineaiy of 0.04% maximum, fo boh inpus. All semiconducos used-in his design ae hemeically sealed. Unlike mos high accuacy muliplies embodying he modulaion pinciple, 427's high caie fequency allows a bandwidh aing of 100kHz fo -3dB esponse wih no caie ipple on oupu. Depending on how i is conneced, he 427 can be used fo muliplying, dividing, squaing, o squae ooing. The Ue capabiliy of a muliplie can be bes demonsaed when he uni is used in he divide mode, paiculaly wih small denominaos. Because he 427 feaues excellen small signal lineaiy, he eos ae vey much smalle han one would pedic using 10/x fo divide eo. MODEL 424 (HGH ACCURACY): The model 424 ]/K is an unimmed muliply-only module wih pefomance compaable o ha of model 427. n evey espec, excep fo he divide and exenal im feaues, he 424 will pefom he 427 ask a lowe componen cos and should be consideed fo laboaoy and indusial applicaions whee exenal imming may be convenienly pefomed o achieve he highes possible accuacies. When exenally immed, model 424 will pefom wih 0.2% (424]) and. 0.1 % (424K) accuacies wih bandwidhs o 100kHz (- 3d B). may be used o pefom division when opeaed wih an exenal op amp.
