TheES5116islowpowermonolithicCMOS31/2digit LCD display A/D converter. It contains the internal clock, voltage reference,seven-segmentdecoders, LCD display drivers and a back plane driver. The improved internalzenerreferencevoltagecircuitgivestheanalog common a small temperature coefficient of C typically. The high accuracy characteristics of the ES5116 perform very low linearity error and roll-over error. The high input impedance ( ) and low input leakage current (1pA typical) give the ES5116 a good application in the field of high impedance circuit measurement. The differential input and reference are suitable for measuring bridge transducer or ohms by using ratio-metric method. The dual slope conversion technique makes the ES5116 a good normal and com-monmoderejectionratio. Withasuitableoscillatorfre-quency,theES5116hasahighrejectionof50Hz,60Hz nd 400Hz line frequency noise. With single power upply, a few passive components and a LCD display, S5116 can be built as high performance panel meter. xisting Display hold, low battery flag integration and De-integrationarefouradditional features.
