ve full-scale fine calibration. IISRC reference current by RISRC and 9-pin voltage is set. V1 and V2 composed of current mirror, the current gain of 14 times, allow the excitation current IBR 14IISRC. IBR programming range is 0.1 ~ 2mA. Analog switches S1, S2 on-off state governed by the configuration registers. Obviously, when the full-scale output voltage changes, DAC3 bridge will be compensated by changing the output voltage, BR, thereby correcting the full-scale error. DAC4 full scale temperature coefficient for correcting errors.
