Choosing an ADC and Op Amp for Minimum Offset
Designing a mixed-signal circuit containing analog and digital components can be a challenge to the development engineer. Requirements such as a low single-polarity supply voltage and a high degree of precision may conflict, and make the choice of components and the best circuit design difficult. This report discusses problems that arise in using operational amplifiers (op amps) for signal conditioning, and in interfacing a 10-bit A/D converter to a digital signal processor.
