Open publisher page 1 citations

Abstract

This paper describes instrumentation, software and acquisition of test data to determine the linearity and monotonicity of the THS5651IDW digital to analog converter (DAC), a prototype of the future Texas Instruments TLV5651, 10-bit, 125 MHz communication DAC.The THS5651IDW is a 5-4-1 segmented current steering DAC.Data was collected at the Texas Instruments' facility on Forest Lane, Dallas Texas.Instruments, software, and laboratory space was provided by Texas Instruments.LabView ® software was used for instrument control, data acquisition, and calculation of linearity data.Linearity data is expressed as differential nonlinearity (DNL) and integral nonlinearity (INL).Analysis of the data found the THS5651IDW DAC to be monotonic since the magnitude of the DNL were less than ± 1 LSB and the INL were less than ± 0.5 LSB.
