GENERAL DESCRIPTION
Aeroflex’s RHD5958 is a radiation hardened, single supply, 8-Channel Multiplexed Analog-to-Digital
converter in a 48-pin Ceramic Quad Flat Package. The RHD5958 design uses specific circuit topology and
layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make
the RHD5958 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 RHD5958 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION
The RHD5958 takes 8 analog sensor signals and using 3 address inputs and an enable input, selects one of
the 8 analog inputs 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
RHD5958s. This provides the ability to interface many sensor voltage readings to the digital processor data
bus. The full-scale range is determined by reference input voltages. The input impedance of the
reference/span terminals is typically a constant 4K ohms.
