It has a built-in internal voltage reference and operates with a supply voltage range from 2.3V to 3.6V. The DAC is controlled by a signal transmit through a 2-wire I2C serial interface which operates in an I2C fast mode (400 k Hz). The VM149D is designed for applications such as image stabilization, autofocus in camera phones, and other portable devices.

Page1 Terminology Resolution The DAC resolution is defined by the power factor of 2, which defines the number of distinct digitized levels. N-bit resolution -> 2N distinct digitized levels Differential Nonlinearity (DNL) error The variation in digitized step value away from 1 LSB by any two adjacent digitized levels, gain and offset errors removed. 120m A, 10Bit Current Sinking VCM Driver with I2C Interface Version：A.003 未經授權而逕予重製、複製、使...
