Product details

Description

DESCRIPTION MAS6240 is a piezo driver device that can drive outputs up to 18Vpp from 3V supply.An internal three-mode charge pump generates boosted supply voltage for piezo driver.For adjusting the piezo element sound volume, the charge pump can operate in either of a 1x, 2x or 3x mode.In 1x mode the input voltage is bypassed to the output, in 2x or 3x mode the input voltage is boosted up accordingly 2 or 3 times.Charge pump mode is selected by control pins EN1 and EN2 (see Table1 at page
