SiTI VM149C
The VM149C is a VCM (Voice Coil Motor) driver IC with I2C interface control that is capable of programmable sinking output current. 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 kHz).| Part No. | VM149C |

Page1 VM149C 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. 120mA, 10Bit Current Sinking VCM Driver with I2C Interface Version...
