GENERAL DESCRIPTION
Aeroflex’s RHD5964 is a radiation hardened, single supply, Voltage Reference in a 3-pad SMD-0.5 Packages. The RHD5964 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5964 especially suited for the harsh environment encountered in Deep Space missions. It is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534 Class K, the RHD5964 is ideal for demanding military and space applications.
The RHD5964 integrated circuit die is mounted directly to the metal signal pad providing optimum thermal conduction to the printed circuit board bond sites.
