GENERAL DESCRIPTION
Aeroflex’s RHD5901 is a radiation hardened, single supply, quad operational amplifier with enable in a
16-pin SOIC package. The RHD5901 design uses specific circuit topology and layout methods to mitigate
total ionizing dose effects and single event latchup. These characteristics make the RHD5901 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 RHD5901 is ideal
for demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5901 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 also operate
properly at power supplies down to 3.0V. 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 RHD5901 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.
