Short Circuit Tolerant Full military temperature range Designed for aerospace and high reliability space applications Packaging – Hermetic ceramic SOIC - 20-pin, 0.30"W x 0.50" L x 0.12"Ht SOIC - Typical Weight 1.6 grams GENERAL DESCRIPTION Aeroflex’s RHD5905 is a radiation hardened, single supply, differential, instrumentation, quad operational amplifier with enable in a 20-pin SOIC package. The RHD5905 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5905 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 RHD5905 is ideal for demanding military and space applications. ORGANIZATION AND APPLICATION The RHD5905 amplifiers are capable of rail-to-rail input and outputs. Performance characteristics listed are for general purpose operational 5V CMOS amplifier applications. The amplifiers will drive substantial resistive or capacitive loads and are unity gain stable under normal conditions. Resistive loads in the low kohm range can be handled without gain derating and capacitive loads of several nF can be tolerated. CMOS device drive has a negative temperature coefficient and the devices are therefore inherently tolerant to momentary shorts, although on chip thermal shutdown is not provided. All inputs and outputs are diode protected. The devices will not latch with SEU events to above 100 MeV-cm2/mg. Total dose degradation is minimal to above 1Mrad(Si). Displacement damage environments to neutron fluence equivalents in the mid 1014 neutrons per cm2 range are readily tolerated. There is no sensitivity to low-dose rate (ELDRS) effects. SEU effects are application dependant. The RHD5905 is configured with enable/disable control. Pairs of amplifiers are put in a power-down condition with their outputs in a high impedance state. Several useful operational amplifier configurations are supported where more than one amplifier can feed an output with others disabled.
