Description
The HS-565BRH is a fast, radiation hardened 12-bit current output, digital-to-analog converter. This part replaced the HS-565ARH, which is no longer available. The monolithic chips include a precision voltage reference, thin-film R-2R ladder, reference control amplifier, and twelve high-speed bipolar current switches. The Intersil Dielectric Isolation process provides latch-up free operation while minimizing stray capacitance and leakage currents, to produce an excellent combination of speed and accuracy. Also, ground currents are minimized to produce a low and constant current through the ground terminal, which reduces error due to code-dependent ground currents. HS-565BRH die are laser trimmed for a maximum integral nonlinearity error of ±0. 25 LSB at +25 °C. In addition, the low noise buried zener reference is trimmed both for absolute value and minimum temperature coefficient. Specifications for Rad Hard QML devices are controlled by the Defense Supply Center in Columbus (DSCC). The SMD numbers listed here must be used when ordering. Detailed Electrical Specifications for these devices are contained in SMD 5962-96755.

Can I ground the "NC" pins of HS-565BEH and HS-565BRH rad hard DACs?
Question:We are very much concerned about electrostatic charge build-up on the no connect pins. Are the "NC" inputs, pins 1 and 2, floating pins or are they internally connected to the die for test purposes? If they are floating, then we must connect them to ground. Answer: Pins ...

What is the update rate of the HS-565BEH or HS-565BRH DAC?
Question: There is not an update rate specification in the data sheet for these digital-to-analog converters. What is the update rate? Answer: The speed at which this DAC can operate depends upon the choice of amplifier used on the DAC's output and upon the output accuracy requirement ...
