10-Bit Digital-to-Analogue Converter
Description
The WM5615 is a 10-bit voltage output digital-to-
analogue converter (DAC) with a buffered reference input
(high impedance). The DAC produces a maximum output
voltage that is twice the reference voltage and the DAC is
monotonic. The device is simple to use, running from a
single supply of 5V. A power-on reset function is
incorporated to ensure repeatable start-up conditions.
Digital control of the WM5615 is over a 3-wire serial bus
that is CMOS compatible and easily interfaced to industry
standard microprocessor and microcontroller devices. The
device receives a 16-bit data word to produce the
analogue output. The digital inputs feature Schmitt
triggers for high noise immunity. Digital communication
protocols include the SPITM, QSPITM and MicrowireTM stand-
ards.
The 8-terminal small-outline D package allows digital
control of analogue functions in space-critical applications.
The WM5615C is characterised for operation from 0oC to
70oC. The WM5615I is for operation from -40oC to 85oC.
