Description
WM5628L and WM5628 are Octal 8-bit digital to analogue converters (DAC) controlled via a serial interface. Each DACs output voltage range is programmable for either x1 or x 2 its reference input voltage, allowing near rail to rail operation for the x 2 output range. High impedance buffered voltage reference inputs are provided for each group of four DACs. WM5628L operates on a single supply voltage of 3 V while WM5628 operates on 5 V.

Features
• Eight 8-bit voltage output DACs
