Overview
WM5620L, WM5620 Production Data Sept.
1996 Rev 2 3 & 5V Quad 8-Bit Voltage Output DAC with Serial Interface Description WM5620L and WM5620 are quad 8-bit digital to analogue converters (DAC) controlled via a serial interface.
Each DAC's 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.
WM5620/L interfaces to all popular microcontrollers and microprocessors via a three wire serial interface with CMOS compatible, schmitt trigger, digital inputs.
An 11 bit command word comprises 2 DAC select bits, an output range selection bit and 8-bits of data.
Individual or all DAC outputs are changed using WM5620/ L's double buffered DAC registers and the separate LOAD and LDAC inputs.
DAC outputs are updated simultaneously by writing a com...
