GENERAL DESCRIPTION
Aeroflex’s RHD5940 is a radiation hardened, single supply, 14-Bit Analog-to-Digital converter in a 24-pin
SOIC package. The RHD5940 design uses specific circuit topology and layout methods to mitigate total
ionizing dose effects and single event latchup. These characteristics make the RHD5940 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 RHD5940 is ideal for
demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5940 takes an analog signal and performs a 14-bit successive approximation analog-to-digital
conversion in a nominal period of 20uS. The 14-Bit digital output has a tri-state control allowing the
connection of multiple RHD5940s. This provides the ability to interface many voltage readings to the
digital processor data bus. The full-scale range is determined by reference input voltages which will
typically include any ~ 4 volt span anywhere in the power supply range (nominal 5V supply). The input
impedance of the reference/span terminals is a constant 4K ohms.
Gain compression will occur near either power supply extremes but can be avoided if the references are
more than 200mV away from the respective supply terminals. The input span can be less than 4 volts at the
expense of ultimate resolution
