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 multiple RHD5950s. 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.
