Working principle of es9023 audio decoding chip

ES9023 Is the U.S. ESS One of the company's 24bit Stereo sound frequency digital to analog conversion chip （DAC）, In chip integration 2Vrms Output driver op amp .
ES9023 Using the industry's advanced SABRE Count - Analog to digital conversion technology , This chipset has the best sound quality 、 Cost effective , Make it an ideal choice for digital to analog conversion . It can be used in Blu ray player 、CD/DVD、 High definition set top box 、 Products such as digital TV or audio receiving equipment .

ES9023 Ultra linear flow using patented technology internally （Hyperstream) Architecture and time domain jitter elimination technology , Make it possible to achieve jitter free recording level sound quality , The dynamic range reaches 112dB.
The charge pump integrated in the chip can generate negative voltage ,ES9023 It can be directly output by reference to the ground wire under the single power supply 2Vrms, The coupling capacitor eliminates DC voltage isolation . and , The output amplitude can be adjusted according to actual needs , Set the resistance to less than 2Vrms level . The on-off noise can also be fully suppressed . Dedicated control / The status pins allow easy integration into the system without single-chip control .
ES9023 yes ESS The company has a single end output DAC chip , It's also their SABRE DAC Unique in the series 、 A simple one , It is generally recognized as the most easy decoding chip to produce good sound . stay 3.6V Under power supply, our actual test output can be greater than 2Vrms, And there is no coupling capacitor structure , Don't bother looking for expensive coupling capacitors , There is no need to worry about audio distortion caused by capacitors （ This is usually the case ）. In addition, we use 32ohm Earphones are also found to drive very well , But the output amplitude will be slightly reduced . And for connecting the power amplifier 、 Circuits such as earphones , Not to mention .
In audio DAC Decoding domain , The United States ESS Is one of the best . Learn more about America ESS Audio DAC Technical application of decoding chip , Please log in to the official website of gongcai.com for consultation .
