102.3mA, Current Sinking, 10-bit, I

C DAC

Preliminary

PT5661

DESCRIPTION

The PT5661 is a single 10-bit DAC with 102.3mA output current sink capability. It features an internal

reference and operates from a single 2.3V to 5.5V supply. The DAC is controlled via a 2-wire

C-compatible) serial interface that operates at clock rates up to 400KHz. The PT5661 incorporates a

power-on reset circuit, which ensures that the DAC output powers up to 0V and remains there until a

valid write takes place. It has a power-down feature that reduces the current consumption of the device

to 1μA maximum. The PT5661 is designed for autofocus, image stabilization, and optical zoom

applications in camera phones, digital still cameras, and camcorders. The PT5661 also has many

industrial applications, such as controlling temperature, light, and movement, over the range -40°C to

+85°C without derating. The I

C address of the PT5661 is 0x18h.
