SGM4806/SGM4807/SGM4808 Click-Pop Noise Suppressors

SGMICRO has recently introduced a series of low distortion, high quality click-pop eliminators: SGM4806, SGM4807 and SGM4808. The SGM4806 and SGM4808 are series solution click-pop eliminators with an operating voltage range of 2.7V to 12V. The SGM4807 is a parallel solution from a single1.5V to 5V power supply.

The POP sound from turning on & off the power or from performing pause and song switching functions has been affecting the user experience for a long time. The common solution is to use discrete component circuits, however this solution is quite complicated, difficult to adjust and bulky. To solve this issue, SGMICRO has developed a timing control POP sound eliminating product SGM4807 and POP sound suppression switch products SGM4806 & SGM4808. This series of click-pop eliminators have solved the problem perfectly along with low distortion and small packages, it will be ideal for smart phones and other audio applications with POP sound issues.

The SGM4806/7/8 are available in Green WLCSP, TQFN and SOIC packages. They operate over an ambient temperature range of -40℃ to +85℃.
