AD5805BCBZ-REEL7

Overview

The AD5805BCBZ-REEL7 is a lens driver integrated circuit manufactured by Analog Devices Inc., housed in a 32-LFCSP package. It functions as a digital-to-analog converter (DAC) specifically designed for autofocus actuator control, delivering up to 120mA output current. The device operates on analog and digital supply voltages ranging from 2.7V to 5.5V. It features a 2-Wire I2C compatible interface for data communication. The component supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated high-current output stage capable of driving voice coil motors directly
• Digital interface compatibility with standard two-wire serial protocols
• On-chip regulation supporting wide supply voltage ranges

Applications

• Autofocus motor control in mobile camera modules
• Optical image stabilization actuator drivers
• Lens positioning systems in compact imaging devices

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging configuration. Confirm the BCBZ designation matches the required lead-free and RoHS compliance status for your assembly process. Ensure the 32-LFCSP footprint aligns with your PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when direct drive capability for small voice coil motors is required without external power amplifiers. The I2C interface simplifies system architecture by reducing pin count compared to parallel DACs. Consider the 120mA output limit against your specific motor coil resistance and required focusing speed requirements.

Part Context

This part belongs to the AD5805 family of lens drivers designed for portable electronics. It integrates DAC functionality with power stages to streamline autofocus implementation. The BC grade indicates specific performance tolerances defined by Analog Devices for automotive or industrial reliability standards within the consumer electronics sector.

Replacement Considerations

Check for AD5805 variants with different thermal pads or suffixes if lead-free processing is mandatory. Verify mechanical compatibility with existing 32-LFCSP footprints before substituting.
