Housed in a compact 57 mm x 30 mm package, Apex’s newest hybrid is provides a low noise density of ~ 5 nV/√Hz @ 1 kHz


TUCSON, Arizona, U.S.A. ––The new PA194 from Apex Microtechnology 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 ~ 5nV/√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.
