10-Bit Digital-to-Analogue Converter

Description

Features

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 SPI^TM, QSPI^TMand Microwire^TMstand-

ards.
