Large voltage glitches (up to 1.5V) can occur during the DAC’s major-carry transitions in an R-2R DAC design with supply voltages higher than 5V. These errors may spread via the output buffer amplifier and manifest themselves at the output.
The problems are brought on by the slewing of the level shifters that operate the top and bottom single-pole double-throw switches. Deglitching is the term for the methods employed to control such issues.
Utilizing an external track/hold (T/H) amplifier after the DAC output is a deglitching approach. This method has the benefit of being able to totally eliminate DAC output errors (in principle).
The Global deglitcher market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
For driving power switches (deglitching) utilised in a range of power supply, inverter, and motor control applications, SkyWorks’ Si827x isolators are the best choice. The Si827x isolated gate drivers, which offer up to 2.5 kVRMS withstand voltage in accordance with UL1577 and VDE0884, employ Skyworks’ own silicon isolation technology.
With the help of this technology, it is possible to achieve industry-leading common-mode transient immunity (CMTI), precise timing requirements, decreased temperature and age variation, improved part-to-part matching, and extremely high reliability.
Additionally, it provides distinctive characteristics including distinct pull-up and pull-down outputs, driver shutdown on UVLO fault, and accurate dead-time programmability. In comparison to opto-coupled gate drivers, the Si827x series delivers significantly improved reliability and a longer service life.
The Si827x drivers make use of Skyworks’ exclusive silicon isolation technology, which offers quick propagation durations of 60 ns and withstand voltages of up to 2.5 kVRMS as per UL1577.
Driver outputs can be connected to either a positive or negative voltage or grounded to either independent or common grounds. The Si8271/2/3/5) or Si8274 (PWM input) variants are available for the TTL level compatible inputs with >400 mV hysteresis.
