RadHard-by-Design Analog RHD5963 2.00 Volt Precision Reference and Buffered Thermometer Released Datasheet Cobham.com/HiRel March 29, 2016 The most important thing we build is trust FEATURES Operating voltage range: 3 volts to 6 volts. Radiation performance - Total dose: - ELDRS Immune - SEL Immune - Neutron Displacement Damage > 1 Mrad(Si); Dose rate = 50-300 rad(Si)/s > 100 MeV-cm2/mg > 1014 neutrons/cm2 2.00V Precision Voltage Reference Buffered Thermometer Sleep Mode (EN = 0) disables all bias generators Power at 5 volts < 7.5 mW Full military temperature range Designed for aerospace and high reliability space applications Packaging – Hermetic Ceramic Hermetic Surface Mount Power 5 Pads, .545"L x .296"W x .120"Ht Weight - 2.0 gm max Radiation Hardness Assurance Plan: DLA Certified to MIL-PRF-38534, Appendix G. GENERAL DESCRIPTION The RHD5963 is a radiation hardened, single supply, Voltage Reference and Buffered Thermometer in 5-pad Power SMD Packages. The RHD5963 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5963 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 RHD5963 is ideal for demanding military and space applications. The RHD5963 integrated circuit die is mounted directly to the metal signal pad providing optimum thermal conduction to the printed circuit board bond sites. The RHD5963 has an external enable signal (EN) which, when set low, enables a "Sleep Mode" that disables all internal bias generators and sets both the Thermometer & Reference outputs to an OFF state resulting in a reduced current consumption to below 600 nA.
