General Description
The AT5510 is a single 10-bit DAC with 120mA
output current sink capability. It operates from
2.7V to 5.5V supply. The DAC is controlled via
2-wire (I
2
C-compatible) serial interface that
operates at clock rates up to 400KHz.
The AT5510 provides a power-down mode. The
power-down mode can be enabled by PD pin or
I
2
C interface. At power-down mode, the output
current reduces to 1
µ
A maximum.
The AT5510 is designed for autofocus, image
stabilization, and optical zoom applications in
camera modules.
The AT5510 is available in DFN-8 or WLCSP
package.
Applications
• Auto-focus of camera modules
• Shutters
• Lens covers
• Image stabilization
