DESCRIPTION

The WM2618 is a dual 12-bit voltage output, resistor string, digital-to-analogue converter. A power-on-reset function ensures repeatable start-up conditions.

The device has been designed to interface efficiently to industry standard microprocessors and DSPs, including the TMS320 family. The WM2618 is programmed with a 16-bit serial word. The WM2618 has a simple-to-use single 2.7V to 5.5V supply. The digital inputs feature Schmitt triggers for high noise immunity.
