RadHard-by-Design Analog Function Series

RadHard-by-Design Analog Function Series

Aeroflex announces its new line of RadHard-by-Design Analog Function Products for LEO, GEO, MEO and Deep Space missions. Our initial offerings are Op Amps, Comparators, Analog Muxes, Digital-to-Analog and Analog-to-Digital Converters.

The Aeroflex RHD series will provide spacecraft designers with a complete set of building blocks to support rapid and affordable implementation for RadHard Analog Circuit applications on space programs.

Note: Aeroflex Plainview’s Radiation Hardness Assurance Plan is now DLA Certified to MIL-PRF-38534, Appendix G.

RadHard-by-Design

All components in the RHD series utilize a consistent and proven set of design and layout techniques to achieve superior radiation performance characteristics. The products are fabricated with a CMOS process and are inherently ELDRS-free and neutron displacement damage immune up to 1014 n/cm2. The development approach to the RHD series leverages higher complexity, mixed-signal products that have proven radiation performance as well as flight heritage.

The functional variety, high performance, low power, and radiation hardness of the RHD series provides spacecraft designers a highly effective set of new tools for spacecraft communications, sensor integration, and signal processing.

 Features / Description
RHD5940 24 Pin 5962-1220701KXC The RHD5940 14-Bit A-to-D uses a successive approximation algorithm to convert the analog input signal to 14 digital output bits at a rate of 50 kSPS. The 14-bit digital output has a tri-state control allowing the connection of multiple RHD5940s.
RHD5950 48 Pin
CQFP		 5962-1220301KXC The RHD5950 takes 16 analog sensor signals and using 4 address inputs and an enable input, selects one of the 16 analog inputs and converts the signal to 14 digital output bits.
