Modular Product Design Combines Digital System Interface With High
Voltage, High Current Power Amplifier to Simplify Driver Circuitry
TUCSON, Ariz.--(BUSINESS WIRE)--Apex Microtechnology is making the design of power analog drive
circuitry for industrial ink jet printer nozzles less of a challenge by
pairing a high performance power amplifier with a digital front end. The

MP113 is a complete solution for implementing multi-pulse waveforms
required to drive a changing number of print nozzles with quality and
accuracy in large format printing applications.
The MP113 features onboard firmware that controls a dual channel
amplifier that allows the user to define the desired waveform for their
specific end system. The amplifier is rated at >10A PEAK per channel
with a voltage supply operation of 180V and up to 135V of output voltage.
“The MP113’s graphical user interface provides a simplified solution
that is easy to implement with an existing drive system or an entirely
new design,” explains Apex Strategic Marketing Manager Jens Eltze. “The
MP113 supports expanded printing capabilities including the use of
grayscale and the ability to change droplet sizes for greater intensity
which is needed to print higher resolution images.”
The modular design of the MP113 is in a broader sense its own evaluation
kit. The embedded firmware allows users to test various parameters such
as the size and speed of droplet formation and to optimize these
specifications for specific types of ink. The MP113 also is designed
with protection and diagnostic features to enhance the overall
reliability of the system.
In terms of electrical performance, the output for the MP113 is
referenced to ground and not the negative supply rail, thus eliminating
the need for a high current negative supply. A low current negative
supply (≤50mA) allows input to zero volts without violating the common
mode input range. The MP113 also provides thermal efficiency with a
power dissipation rating of up to 100W per channel.
