GENERAL DESCRIPTION
Aeroflex’s RHD5904 is a radiation hardened, single supply, high speed, quad operational amplifier with
enable in a 16-pin SOIC package. The RHD5904 design uses specific circuit topology and layout methods
to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5904
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
RHD5904 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5904 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 RHD5904 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.
