Description
WM5620L and WM5620 are quad 8-bit digital to analogue converters (DAC) controlled via a serial interface. Each DACs output voltage range isprogrammable for either x1 or x 2 its reference input voltage, allowing near rail to rail operation for the x 2 output range. Separate high impedance buffered voltage reference inputs are provided for each DAC. WM5620L operates on a single supply voltage of 3 V while WM5620 operates on 5 V.

Features
• Four 8-bit voltage output DACs
• Three wire serial interface
• Programmable x1 or x 2 output range.
• Power-on-reset sets outputs to zero
• Buffered voltage reference inputs
• Simultaneous DAC output update
• 14 pin SO or DIP package

Applications
• Programmable d.c. voltage sources
• Digitally controlled attenuator/amplifier
• Signal synthesis
• Mobile communications
• Automatic test equipment
• Process control
