MP206KP: 2-Channel Power Amplifier Print Head Driver.
The MP206 is a 2-channel high output power amplifier for driving capacitive loads such as piezo devices
used in inkjet printing applications. The amplifier provides flexibility in output drive; it can provide positive or
negative pulses to a constantly changing number of piezo nozzles. MP206 is built on a thermally conductive,
but electrically isolated substrate, delivering high power in a very compact module.
The amplifier gain is fixed at approximately 20V/V in non-inverting mode (or -15.5V/V for inverting
mode). It is optimized to achieve a 0 to 40V (or -40 to 0V) output voltage swing. A combination of internal and
external compensation allows MP206 to be tailor-fit to any of the print heads listed above, providing optimum
slew rate and ensuring stability. Auxiliary voltages (+VB and -VB) for the amplifier stage are used to
reduce the power loss in the output drivers.
