GENERAL DESCRIPTION
Aeroflex RHD5902 is a radiation hardened, single supply, high speed quad operational amplifier with enable in a
16-pin SOIC package. The RHD5902 design uses specific circuit topology and layout methods to mitigate total
ionizing dose effects and single event latchup. These characteristics make the RHD5902 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 RHD5902 is ideal for demanding military
and space applications.
ORGANIZATION AND APPLICATION
The RHD5902 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-cm
2
/mg. Total dose degradation is minimal to
above 1 Mrad(Si). Displacement damage environments to neutron fluence equivalents in the mid 10
14
neutrons
per cm
2
range are readily tolerated. There is no sensitivity to low-dose rate (ELDRS) effects. SEU effects are
application Dependant.
The RHD5902 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.
