GENERAL DESCRIPTION
Aeroflex’s RHD5932 is a radiation hardened, single supply, 14-Bit, Buffered, DAC in a 20-pin SOIC
package. The RHD5932 design uses specific circuit topology and layout methods to mitigate Total Ionizing
Dose effects and Single Event Latchup. These characteristics make the RHD5932 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 RHD5932 is ideal for demanding
military and space applications.
ORGANIZATION AND APPLICATION
The Aeroflex RHD5932 14-Bit DAC is a standard CMOS R/2R Kelvin resistor network with a buffered
output. The digital inputs, D13(MSB) through D00(LSB), are buffered to drive single-pole double-throw
CMOS switches to apply either the PREF or NREF signals to the 2R legs of the resistor network.
PREF and NREF inputs can be any static or dynamic voltage within the power supply range. The nominal
values for R and 2R are 4K and 8K respectively. The characteristic impedance of the resistor network is
approximately 4K.
The voltage-output configuration of the integrated circuit can be thought of as a digitally controlled voltage
with a value of PREF-NREF with a high output impedance. The output will swing rail-to-rail if unloaded.
Applications include digital potentiometers, programmable voltage sources and a large variety of other
circuits that can be found in many industry references.
