DESCRIPTION
The WM2616 is a 12-bit voltage output, resistor string digital-to-
analogue converter that can be powered down under software
control. Power down reduces current consumption to 10nA.
The device has been designed to interface efficiently to industry
standard microprocessors and DSPs, including the TMS320
family. The WM2616 is programmed with a 16-bit serial word
comprising 4 control bits and 12 data bits.
Excellent performance is delivered with a typical DNL of 0.5LSBs.
The settling time of the DAC is programmable to allow the designer
to optimize speed versus power dissipation. The output stage is
buffered by a x2 gain rail-to-rail amplifier, which features a Class
AB output stage.
The device is available in an 8-pin SOIC package. Commercial
temperature (0° to 70°C) and Industrial temperature (-40° to 85°C)
variants are supported.
