DESCRIPTION

The WM2633 is a 12-bit voltage output, resistor string, digitalto-analogue converter. A hardware controlled power down mode is provided that reduces current consumption to 10nA. The WM2633 features an internal programmable voltage reference simplifying overall system design. A reference voltage may also be supplied externally.
