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
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
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 […]
Low-power DAC with NVM simplifies handheld designs
Implementing multi-channel system control or signal outputs using Digital-to-Analog Converters (DACs) in today’s portable and handheld industrial, communications, consumer and medical systems has been difficult to do without significant processor overhead for device configuration during power-up. Microchip Technology Inc. announced a solution to this problem with its MCP47/48FxBx8 family of octal 12-bit DACs, the first of their […]
Voice ADC excels at far-field audio
Texas Instruments introduced a new audio analog-to-digital converter (ADC) capable of capturing clear audio up to four times farther away than competing devices. The TLV320ADC5140 is the industry’s smallest quad-channel audio ADC with this level of performance. The device is part of a new family of three TI Burr-Brown audio ADCs that enable low-distortion audio […]

Tiny precision data converters cover 14 thru 24-bit resolution ranges
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 […]
Precision ADCs simplify calibration requirements close to O mA
Analog Devices has introduced today two multi-channel +/-10V and 0-20mA precision A/D converters that better enable implementation of programmable logic controller (PLC) and distributed control system (DCS) modules. Leveraging ADI’s iPassives integrated precision passives technology, the AD4111 and AD4112 A/D converters integrate precision matched current sense resistors and resistor dividers. The high degree of channel-to-channel […]
High fidelity audio apps excel with MUS-IC D/A converters
ROHM has launched a new branding “MUS-IC” reflecting ROHM’s focus on solutions for high-fidelity audio products. This branding covers a range of D/A converter ICs (DAC ICs), optimized for high-fidelity reproduction, and power supply products. The increased adoption of high-resolution audio sources has lately strengthened the demand for audio equipment that can deliver an appropriate sound […]
