GENERAL DESCRIPTION Aeroflex’s RHD5950 is a radiation hardened, single supply, 16-Channel Multiplexed Analog-to-Digital converter in a 48-pin Ceramic Quad Flat Package.
The RHD5950 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup.
It is guaranteed operational from -55°C to +125°C.
Available screened in accordance with MIL-PRF-38534 Class K, the RHD5950 is ideal for demanding military and space applications.
ORGANIZATION AND APPLICATION The RHD5950 takes 16 analog sensor signals and using 4 address inputs and an enable input, selects one of the 16 analog inputs and performs a 14-bit successive approximation analog-to-digital conversion in a nominal period of 20 clock cycles (20uS nominal).
The 14-bit digital output has a tri-state control allowing the connection of...
