DESCRIPTION

The MS6334 is a 16-bits voltage-output Digital-to-Analog Converter (DAC) integrated class AB stereo headphone driver with volume control. It is fabricated in a CMOS process and features extremely low power dissipation, small package size and easy application. The accuracy of the matched coarse current sources, combined with the unique symmetrical decoding method, preclude zero-crossing distortion and ensures high quality audio reproduction. The MS6334 has good feature for portable equipment, these features include the low voltage operation, low power consumption, flexible power management, component less and small package SSOP20, make the MS6334 ideally suited for use in portable digital audio equipments. The MS6335 only has I2C interface, the smaller package SSOP16, QFN16 , and other functions are the same as the MS6334.
