Dac Transfer Function. We do this to avoid operating the output operational amplifier in the non linear region near its power rails. 1 end point inl or 2 best fit inl.
The sigma delta dac we have designed is useful for synthesizing audio signal cd format. Equation binary weighted dac example a 4 bit dac having n4 bits will have 4 digital inputs from 0000 to 1111. 1516 x vref can also be called multiplying dac bs is a digital code it is assumed a 0.
The transfer function has an amplitude response which is inversely proportional to the input frequency.
2 where n is the device resolution 16 14 or 12 bits v 0x0000 is the measured dac zero scale output voltage v 0xffff is the measured dac full scale output voltage. Transfer function dac architectures dac example calibrations agenda. The transfer function has an amplitude response which is inversely proportional to the input frequency. The analog io wildcard comprises a wildcard bus header field header digital logic circuitry an octal 12 bit digital to analog converter dac an octal 16 bit analog to digital converter ad and a 4096 volt reference all the functions needed for data acquisition and high resolution voltage generation in scientific instruments.
