A microdeposition system (20) and method includes a head with a plurality
of nozzles (230). A controller (22) generates nozzle firing commands that
selectively fire the nozzles to create a desired feature pattern.
Configuration memory stores voltage waveform parameters that define a
voltage waveform (280) for each of the nozzles. A digital to analog
converter (DAC) sequencer communicates with the configuration memory and
the controller and outputs a first voltage waveform for a first nozzle
when a nozzle firing command for the first nozzle is received from the
controller (22). A resistive ladder DAC receives the voltage waveforms
from the DAC sequencer. An operational amplifier (opamp) communicates
with the resistive ladder DAC and amplifies the voltage waveforms. The
nozzles fire droplets when the voltage waveforms received from the opamp
exceed a firing threshold of the nozzle (230).
