General Description
The G2003 is a single 10-bit DAC with 120mA output
current sink capability. It operates from 2.3V to 5.0V
supply. The DAC is controlled via 2-wire
(I2C-compatible) serial interface that operates at clock
rates up to 400kHz.
The G2003 provides a power-down mode. The
power-down mode can be enabled by PD pin or I2C
interface. At power-down mode, the output current
reduces to 1μA maximum.
The G2003 is designed for autofocus, image stabiliza-
tion, and optical zoom applications in camera mod-
ules.
