Wolfson Microelectronics plc WM5621L
WM5621L is a quadruple 8-bit digital to analogue converter (DAC) with buffered reference inputs (high impedance). The DAC produces an output voltage that ranges between either one or two times the reference voltage and GND. The device operates from a single supply in the range 2.7V to 5.5V.| Part No. | WM5621L |

DESCRIPTION
The DAC is monotonic. A power-on reset function is incorporated to provide repeatable start-up conditions. A global hardware shut-down terminal and the capacity to shut-down each individual DAC with software are provided to minimize power consumption. WM5621L interfaces to all popular microcontrollers and microprocessors via a three wire serial interface with CMOS compatible, schmitt trigger, digital inputs. Alternatively a two wire serial interface can be activated. An 11-bit command word consists of eight bits of data, two DAC select bits and a range bit for selection between the times one or times two output range. The DACregisters are double buffered which allows a complete set of new values to be written to the device, and then under control of HWACT, all of the DAC outputs are simultaneously updated. Ideal in space critical applications WM5621L is available in small outline and DIP packages and is characterized for operation from -25oC to 85oC.FEATURES
