The R-2R ladder DAC which is a binary-weighted DAC that uses a repeating cascaded structure of resistor values R and 2R. This improves the precision due to the relative ease of producing equal valued-matched resistors. The successive approximation or cyclic DAC, [4] which successively constructs the output during each cycle. Individual bits of ...

A Brooktree RAMDAC. A RAMDAC (random-access memory digital-to-analog converter) is a combination of three fast digital-to-analog converters (DACs) with a small static random-access memory (SRAM) used in computer graphics display controllers or video cards to store the color palette and to generate the analog signals (usually a voltage amplitude) to drive a color monitor. [1]
Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).
The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ADC. The circuit consists of an up-down counter with the comparator controlling the direction of the count.
DAQ cards often contain multiple components (multiplexer, ADC, DAC, TTL-IO, high-speed timers, RAM). These are accessible via a bus by a microcontroller, which can run small programs. A controller is more flexible than a hard-wired logic, yet cheaper than a CPU so it is permissible to block it with simple polling loops.
The Design Automation Conference, or DAC, is an annual event, a combination of a technical conference and a trade show, both specializing in electronic design automation (EDA). DAC receives approximately 1100 research paper submissions annually.
Most recently, ESS SABRE DACs are used in the LG V10 smartphone, with a quad DAC configuration present in the V10's successor LG V20. A slightly upgraded version of the same DAC in the V20, the SABRE ES9218P, [5] is used in the V30 as well as the V40 ThinQ. The ESS9038Pro is their flagship and competes against Japanese AKM (Asahi Kasei ...
