WM5621L - Low-power Quadruple 8-Bit DAC

Datasheet Summary

Description

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 DAC is monotonic.

WM5621L Production Data Jan. 1997 Rev. 1.0 Low-power Quadruple 8-Bit DAC Description 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 DAC is monotonic. The device operates from a single supply in the range 2.7V to 5.5V. 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.
