Section 6-5: DAC and ADC Static Transfer Functions and DC Errors

The four primary DC errors in a data converter are offset error, gain error, and two types of linearity error (differential and integral). Offset and gain errors are ...

Should You Use Audio ADCs For Precision Applications?

There’s another dimension to the THD versus linearity problem as well. This plot represents the linearity error for every code for an 18-bit precision ADC. Using ...

Analog-to-digital converter (ADC) accuracy in simple terms

The previous blog discussed how makers can select an A/D converter by understanding the application and how manufacturers optimize a part for that role. Now, what happens when an A/D fires up—how ...

Basics of ADCs and DACs, part 2

The most important thing to remember about both DACs and ADCs is that either the input or output is digital, and therefore the signal is quantized. That is, an N-bit word represents one of 2N possible ...
