Supertex's MEMS driver tooled for high voltage drive apps
The HV264 will find use in a variety of MEMS and other High Voltage Drive applications, such as driving optical MEMS and piezoelectric transducers. Versus the large amplifier array of most available solutions, the base of 4 amplifiers offers significant advantages in design layout and modularisation to engineers tackling the large mix of applications for MEMS and Piezoelectric solutions. Some areas of application are MEMs micromirror drives as seen in optical networking and communications, test and measurement, printing, component alignment, 3D position tracking and positioning such as for gaming, laser marking, small and transparent displays, biomedical instrumentation and imaging, and more. Potential piezoelectric applications include security sensors, fluid measurement, and more.
The four channels of the HV264 consist of four independent high voltage amplifiers, capable of inverting or non-inverting configurations. The outputs can swing at 9V/µs, measured with a 200V supply and a 15pF load. The HV264 operates with a 200V and a 5V supply. With an integrated high value gain setting resistor for internal feedback (66.7V/V), no external passives for feedback are needed. Internal voltage swing is designed to proceed between 50mV and 2.85V on the input, with the output ranging from 3.33V to Vpp—10V (the dc supply voltage minus 10V.)
Supertex has been a key supplier of solutions in this space, and the Company is working to expand its relationship with other key MEMS suppliers. Supertex will continue to improve its unique process capabilities, and provide increasing levels of service and value to its base of MEMS customers.
