SCHEMATIC SYMBOL
?
Aeroflex Plainview’s Radiation Hardness Assurance Plan is DLA Certified to MIL-PRF-38534, Appendix G.
GENERAL DESCRIPTION
The Aeroflex 11-Bit DAC is a standard CMOS R/2R Kelvin resistor network with a buffered output. The
digital inputs, D10
(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 5K and 10K respectively. The characteristic impedance of the resistor network is
approximately 5K.
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.
