GENERAL DESCRIPTION
Aeroflex’s RHD5910 is a radiation hardened, single supply, high speed, quad comparator in a 16-pin SOIC package.
The RHD5910 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup.
These characteristics make the RHD5910 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 RHD5910 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5910 quad comparator is intended for operation with dynamic signals on either or both inputs.
Comparison is ’continuous’, that is, the circuit functions as high gain open loop amplifiers with a digital output.
For slow input signals with small input differences the comparators can be expected to respond to small noise signals at the inputs.
Feedback hysteresis is the responsibility of the user to avoid ’chattering’ on system noise.
The comparator will accept signals anywhere in the included power supply range.
The circuit delay is specified for a half-volt single ended or differential input step of either polarity ending in an input polarity reversal of 10mV.
