DESCRIPTION
The WM2613 is a 12-bit voltage output, resistor string, digital-to-
analogue converter. The DAC can be powered down under
software or hardware control, reducing power consumption to
10nA.
The device has an 8-bit microcontroller compatible parallel
interface. The eight data LSBs, the four data MSBs, and the three
control bits are written using three different addresses.
Excellent performance is delivered with a typical DNL of 0.4 LSBs.
The output stage is buffered by a x2 gain near rail-to-rail amplifier,
which features a Class A output stage (slow mode, class AB). The
settling time of the DAC is software programmable to allow the
designer to optimize speed versus power dissipation.
The device is available in a 20-pin TSSOP package. Commercial
temperature (0° to 70°C) and Industrial temperature (-40° to 85°C)
variants are supported.
