GENERAL DESCRIPTION
Aeroflex’s RHD5903 is a radiation hardened, single supply, differential output, quad operational amplifier with enable in a 20-pin SOIC package. The RHD5903 design uses specific circuit topology and layout methods to mitigate total ionizing dose effects and single event latchup. These characteristics make the RHD5903 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 RHD5903 is ideal for demanding military and space applications.
