ENOB describes an analog-to-digital converter’s performance with respect to total noise and distortion. In the earlier parts of this series on analog-to-digital converters (ADCs), we looked at the basics (part 1); gain error, offset error, and differential nonlinearity (part 2); integral nonlinearity (part 3); and then we looked at some ADC topologies and introduced AC […]

ADCs target mid-tier audio market
Cirrus Logic has announced the release of four new audio converters for its Pro Audio product family: two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs). The components are designed for HiFi playback systems, installed audio infrastructure, professional audio equipment, musical instruments, and USB audio interfaces. The devices expand the company’s existing converter portfolio to […]
Factory-configurable converters offer sample rates from 20 to 250 Msps
A new data converter platform is now available, offering 10-, 12-, 14-, and 16-bit resolution analog-to-digital converters (ADCs) with sample rates ranging from 20 to 250 megasamples per second (Msps). The devices are part of a scalable architecture that allows factory configuration to meet various application needs in industrial and communication systems. The architecture enables […]
How does a basic digital-to-analog converter (DAC) perform signal conversion?
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 […]
24-bit wideband ADC offers data rates up to 400 kSPS
Texas Instruments introduced the smallest 24-bit wideband analog-to-digital converter (ADC) that delivers industry-leading signal-measurement precision at wider bandwidths than competing ADCs. The ADS127L11, the newest product in TI’s portfolio of precision wideband ADCs, achieves ultra-precise data acquisition in a 50% smaller package, significantly optimizing power consumption, resolution, and measurement bandwidth for a wide range of […]
Dev kit works with ADC for mixed-signal, subsystem implementations
Teledyne e2v has expanded the scope of engineering support accompanying its popular EV12AQ60x analog-to-digital converter (ADC) series. The new EV12AQ600-FMC-EVM development kit will be an invaluable tool for those implementing mixed-signal subsystems. Intended for prototyping work relating to avionics, military, space, telecommunications, industrial, and high energy physics applications, this kit may be used for evaluating […]
SAE ADCs boast sampling speeds of 10 to 125 MSPS
Texas Instruments expanded its portfolio of high-speed data converters with a broad new family of successive approximation register (SAR) analog-to-digital converters (ADCs) that enable high-precision data acquisition in industrial designs. Featuring best-in-class dynamic range at the lowest power consumption, the ADC3660 family includes eight SAR ADCs in 14-, 16- and 18-bit resolution at sampling speeds […]
New 32-bit D/A converter designed for high-fidelity audio
ROHM Semiconductor announced the new BD34301EKV, a 32bit D/A converter IC designed for high fidelity audio equipment, capable of high-resolution playback of audio sources. ROHM also offers BD34301EKV-EVK-001 evaluation boards for testing the new IC’s performance (available via distributor channels). Designed to maximally extract and convert high-resolution audio data to analog, audio DAC chips are one of […]
