fitipower integrated technology lnc. FP5503 120 mA Current Sinking 10-Bit I2C® DAC Description: The FP5503 is a single 10-bit DAC with 120mA output current sink capability. It features an internal reference and operates from a single 2.7 V to 5.5 V supply. The DAC is controlled via a 2-wire (I2C-compatible) serial interface that operates at clock rates up to 400 kHz, then the DAC control the output sink current from 3mA to 120mA. The FP5503 incorporates a power-on reset circuit, which ensures that the DAC output powers up to 0 V and remains there until a valid write takes place. It has a power-down feature (external pin power down or the I2C input control software power down) that reduces the current consumption of the device to 1 μA maximum. The FP5503 is designed for auto-focus, image stabilization, and optical zoom applications in camera phones, digital still cameras, camcorders and other industrial applications. The FP5503 has many industrial applications, such as controlling temperature (heater or cooler control), light, and movement, over the range −40°C to +85°C without derating. The I2C address range for the FP5503 is 0x18 to 0x1F inclusive. Only when the master device initiates the correct address, FP5503 generates an acknowledge condition and works normal. FP5503-1.2-August/2008 Features: ● 2.7 V to 5.5 V power supply (or unregulated) ● 120mA current sink ● 2-wire (I2C®-compatible) serial interface ● 10-bit resolution DAC ● Guaranteed monotonic over all codes ● ...
