DESCRIPTION

The WM2632 is an octal, 8-bit, resistor string digital-toanalogue converter. The eight individual DACs contained in the IC can be switched in pairs between fast and slow (low power) operation modes, or powered down, under software control. Alternatively, the whole device can be powered down, reducing current consumption to less than 0.1μA.
