How does a basic digital-to-analog converter (DAC) perform signal conversion?

May 7, 2025 By Rakesh Kumar

A digital-to-analog converter (DAC) transforms digital binary data into an analog signal using weighted contributions from each bit. In this FAQ, we discuss the two most commonly known ways of DAC conversion: weighted resistor DAC and R-2R ladder DAC. Before getting into the conversion types, let us understand the basic steps involved in a DAC […]

Understanding ADC specs and architectures: part 1

April 9, 2025 By Rick Nelson

Analog-to-digital converters are the heart of most test equipment, setting the stage for the digital processing of analog signals. Several posts over the past year or so have involved digital signal processing. For example, we have covered the fast Fourier transform (FFT), the inverse FFT, and discrete convolution. To perform these operations on real-world signals, […]

Sigma Delta ADC vs. SAR vs. Pipeline: How to Choose

May 24, 2021 By Janet Heath

Assuming that you are familiar with the fundamental specifications of an ADC and what they mean, the next step is to know your entire signal chain well and then work to fit the ADC to the requirements. After carefully determining signal chain requirements, then select your ADC with the understanding that if the ADC is […]

Tiny precision data converters cover 14 thru 24-bit resolution ranges

December 3, 2018 By Aimee Kalnoskas

precision data converters

Texas Instruments introduced four tiny precision data converters, each the industry’s smallest in its class. The new data converters enable designers to add more intelligence and functionality, while shrinking system board space. The DAC80508 and DAC70508 are eight-channel precision digital-to-analog converters (DACs) that provide true 16- and 14-bit resolution, respectively. The ADS122C04 and ADS122U04 are […]
