　　the ct433 is a high bandwidth and ultralow-noise inte.grated contact current sensor that uses allegro patentedxtremesensetm tunnel magnetoresistance (tmr) technol-ogy to enable high-accuracy current measurements formany industrial,consumer,and automotive applications.the device supports multiple current ranges where theintegrated current-carrying conductor(ccc)handles upto 70 a of current and generates a current measurement asa linear analog output voltage. the device achieves a totaloutput error of less than +l% full-scale (fs) overvoltageand the full temperature range. the device has a ~300 nsoutput response time while the current consumption is~6 ma and is immune to common-mode fields. the ct433is optimized for high dv'dt applications, which minimizescapacitive coupling to vout, allowing the ct433 to beused in switching applications. the ct433 is offered in anindustry-standard l6-lead small-outline integrated circuit(soic) wide package that is green and rohs-compliant.
