Apex Microtechnology continues to drive the leading edge of technology innovation for high speed, high voltage power operational amplifiers that can deliver precision high voltage at fast speeds in a variety of applications were speed and accuracy are a must. The new PA194 is a refined implementation of the Apex PA94, extending slew rate capabilities by +1,000 V/μs.
The PA194 has a typical slew rate of 1700 V/μs to enable fast rise and fall times on supply voltage operation of up to 900 V, and a very low noise density of ~5 nV/√Hz @ 1 kHz. The PA194 has a continuous output current capability of 100 mA and exhibits just 4 mA of quiescent current with an integrated standby mode for increased efficiency. This amplifier is available in an 8-pin power SIP package with heat tab and can dissipate up to 30 watts.
“Designers looking to apply very high levels of voltage with precision and speed will certainly want to evaluate the PA194,” explains Apex Strategic Marketing Director Jens Eltze. “We designed this power amplifier to operate with enhanced efficiency and reliability while lowering noise density within the electrical circuitry. The end result will be an increase in overall end-system performance.”
A wide range of target applications include industrial instrumentation, semi-cap test equipment and SEM analysis tools using electron beam focusing, particle deflection and piezoelectric positioning.
Pricing, Availability and Evaluation Tools
Sample units of the PA194 are available now for qualified applications, with production volumes targeted for Q4 2018. Per unit pricing is available by contacting a local Apex sales representative or distributor. The EK66 is the evaluation kit for rapid prototyping with the PA194 and is scheduled to be available in early Q3 2018.
